DIY Home Depot Lights

INCLUDED IN THIS LESSON: In-Depth Written Breakdown

IN THIS LESSON YOU WILL LEARN: Home Depot is an amazing resource for filmmakers and slowly the industry is starting to realize the possibilities. In this lesson, Shane Hurlbut, ASC takes you through some of the lights he’s designed out of Home Depot and what they are best suited for. This is an in-depth look at DIY lighting and how to control your sources on a budget.

  • Understanding what DIY is and why it’s the next step in the evolution.
  • The Pros and Cons of DIY.
  • How to be creative with your resources at hand.
  • How to be crafty with your lights.
  • Understanding the best methods for mixed light and utilizing DIY lights on the day.
  • Additional lighting accessories you can purchase at Home Depot.

The high ISO range to minimum noise ratio of newer cameras opened up a whole new way to light as a cinematographer. Whether it be daylight interior or exterior, dawn, dusk, night exterior or interiors the option now exist to use available light in new ways, as well as working with less. On the films that I shot prior to Act of Valor, our lighting package fit into a 48’ semi truck along with multiple 10-ton truck drop loads to expose film. We are in very exciting times and they are being shaken again with Canon’s November 3rd announcement . Using available light is one thing, but shaping the available is what cinematography is all about. Just because you can, doesn’t mean you should.

Here is a perfect example. St. Germain Puerto Rico. We needed to light 8 city blocks. I had two lighting technicians. So I rented two 1200 watt HMI par lights and a 3000 Watt Honda Generator that I hid behind the church to block the sound so that it would not effect our dialogue. Added six 4’ green and yellow single KINO Flos in the store windows behind the actors as they walk in the plaza, this would also help add color dimension as well as great out of focus highlights when I went in for close ups. Their key light would be two stings of carnival bulbs that were 200’ long, and the edge/back lights would be the street lamps that lined the side of the plaza as they took their stroll. There was way too much light at 1600 ISO. So I started to manicure and shape the wide shot. Bottom left corner I used black wrap to block out the streetlamp because it was too hot on the left side of frame and took my eye away from the actors on the cobblestone street in the center of the plaza.

The building on the left that has a coolish tone was smoking hot. I wrapped Neutral Density .9 gel around that so that I kept the cool color contrast but it took it down. A church is such an important part of the Hispanic culture. I wanted to highlight the steeple as well as its body. We were under serious time constraints that day and I should have taken the 1200 HMI par down about two stops that hit the body of the church. The steeple looked great but I burned the church up just a bit too much. I added Rosco full plus green to the HMIs so that they felt dirty and not perfect.

Here are the units that lit the Plaza:

My lighting package now is pretty much everything you can either purchase from Home Depot or out of a Grainger catalog. I always used practical light to motivate my sources but now the practical can be the source. There is no need to hide lights or hang them to simulate what that particular light would be doing. I have a very simple package which is a mix of some movie lights, some theatrical lights and then your local hardware store. Here you go:


4-Single bulb shop fluorescents w/ cool white tubes, with daylight & tungsten bulbs. Vitalight for Daylight and Optima 3200 for Tungsten. This is easy to hide behind bars, bottles, in corners, great top light in a garage, office, etc.

4-Dbl Bulb shop fluorescents w/ cool white tubes, with daylight & tungsten bulbs. Vitalight for Daylight and Optima 3200 for Tungsten. This is easy to hide behind bars, bottles, in corners, great top light in a garage, office, etc. On Swing Vote I hung 4 double units in the kitchen with cool white globes in them to give a cool/green feel in Bud’s trailer. It felt real and not so polished.

4-12” Silver Reflector Clamp lights w/ 150 watt globes, 50 watt Halogen Spots. You can add diffusion on the front if you would like to make it softer. This can be used as a harder source with a spot globe.

4-6” Silver Reflector Clamp lights w/ 100 watt globes, 50 watt Halogen Spot

4-18” Under Cabinet Fluorescent w/ cool white tubes, with daylight & tungsten

6-MR-16 50 Watt Flood screw in household socket

6-Household socket dimmers

6-1000 Watt in-line dimmer

6-600 Watt Wall outlet dimmers

2-70 Watt Dusk to Dawn lamps Metal Halide (MH) This is my go to source for lighting the exterior of barns, houses, and in the case of Swing Vote this Dusk to Dawn was to illuminate his driveway to his trailer and bring ambience to his truck driving in at night. I also mounted it to Kate’s garage to give me some color contrast in the deep background. They’re so versatile, lightweight and require little power.

2-100 Watt Dusk to Dawn High Pressure Sodium (HPS)
I used this in the night scene on Swing Vote where Molly finds Bud in his car drunk. She walks down the street and then gets to his truck and looks off camera. The HPS fixture is giving her a beautiful back light and then I used a 12 x 12 ultra bounce to reflect light into her face.

2-Wall mounted 70 Watt High Pressure Sodium (HPS)
Great to mount in background of night exteriors for out of focus highlights, hide in tight spaces to light people.

2-50’ Strands of Rope light, I use this to light under counters, under cabinets in kitchens. I use very long strands of it that I fold back and forth on itself about 6 times to create what we call a colon light. Look at the still shot from Act of Valor. That warm glow in the background was the colon rope light giving that beautiful glow.

1- LED Hockey Puck Light kit w/ 3 heads perfect to light paintings, under light bars, streak walls, light bar backs, under light bottles,etc.

2- 100 Watt Tungsten Hockey Puck lights, perfect to light paintings, under light bars, streak walls, light bar backs, under light bottles,etc.

2-12”, 2-18”, 2-24”, 1-30” China Balls w/ 100 watt & 150 watt globes. These are beautiful key and or fill lights. I use black wrap to shape them sometimes by blacking the back half to cut down on spill. Philippe Rousselot uses these on every film he shoots, wonderful soft ambient lighting tool for cheap.

1- Fluorescent Trouble light, hang in places quickly to give yourself nice out of focus highlights in the background

4-50’ 12 Gauge Stingers

4-25’ 12 Gauge Stingers

6-Power Strips

8- Cube taps

This lighting package should get you started on your way to create and light on a budget. Try new things work with less and see how it turns out. Remember the secret to exposing HD is to starve the CMOS chip of light.

Grow Light Breakdown: Heat, Cost & Yields

For the many growers who are unable to cultivate cannabis outside in the free abundant sunshine, grow lights are necessary to successfully grow cannabis indoors. Grow lights take the place of the sun, and power the growth of your plants and their buds. Light is like “food” for your plants, so without a lot of bright light, even a healthy cannabis plant won’t produce much bud at all.

More Light = Bigger Yields!
(up to a point, it is possible to give your plant too much light!)

3 Main Classes of Marijuana Grow Lights

There are lots of options for grow lights that work well for growing cannabis indoors but in the end they boil down to 3 major types:

  • (LEDs come in a huge variety of sizes and form factors. There aren’t really any “standard” types yet, though some lamps get better results than others.)

Note: Some growers may have heard of “Induction” grow lights, which are pretty rare these days but still pop up from time to time. There are two types: “Magnetic Induction” grow lights do okay for growing cannabis but they’re pretty much glorified fluorescent lights. “Plasma Induction” grow lights actually perform pretty poorly at growing cannabis.

Some types of induction lights are well suited to stadium lighting but honestly they just aren’t that great for growing cannabis and they come with huge price tags. Even a lot of LEDs are cheaper and you’ll get better results with them. You can learn more about induction grow lights here.

Note 2: Incandescent light bulbs (old fashioned light bulbs) are NOT suitable for growing marijuana!

Compare the Pros and Cons of Each Grow Light

1.) Fluorescent Grow Lights

Fluorescent grow lights come in many different shapes and sizes, from twisty bulbs to long tubes. Fluorescents are popular because they make efficient and pleasant lighting for humans, and also work great for herb gardens and other types of low-key indoor gardening without using a lot of electricity.

CFL Grow Lights

CFL grow lights are the twisty-looking bulbs you can find anywhere you normally buy light bulbs. They produce a great spectrum for growing cannabis and can be used in tiny spaces where no other grow light would fit such as the inside of a cabinet.

Keeping CFLs close results in the best yields and growth

T5 Grow Lights

T5 grow lights are one of the most easily available types of grow lights and are used to grow many different types of plants. As a result, they’re available in many garden and home improvement stores.

T5s are much bigger/wider than CFLs and usually come as part of a panel, but they can still be kept mere inches away from your plants without worrying about burning them.

These cannabis plants are thriving under T5 grow lights

Pros of Fluorescents

  • Cheap to buy
  • They don’t use a lot of electricity or make a lot of heat unless you have a lot of them packed together in a small space
  • Great light spectrum for growing cannabis
  • Since lights can safely be kept just a few inches away from plants, they’re a good choice for short spaces
  • One of the best lights for clones, seedlings and young plants. Big lights must be kept far away from young plants to avoid burning them, which ends up wasting a lot of light and energy. By using smaller lights like fluorescents while plants are still short, you can save quite a bit of money on electricity during those first few weeks compared to using a high-powered grow light.

Cannabis plants under a T5 grow light – when plants are trained (like these ones in a Scrog setup) you can get pretty decent yields from fluorescents.

Cons of Fluorescents

  • Fluorescent grow lights get smaller yields per watt than the other types of grow lights if you use them in the flowering stage while buds are forming. With fluorescents you can expect about 0.25 grams of buds for every watt of electricity (using the true watts out the wall, not any type of “equivalent” watts), while LEDs and HPS get 2-4 times as much yield per watt of electricity.
  • The light from a fluorescent lamp doesn’t penetrate far down into the plant so they are best suited to plants that have been trained to grow short and flat; they aren’t powerful enough to support tall plants in the flowering stage.

Fluorescents are a great choice for clones, young plants, supplemental lighting and can save you money on electricity in the vegetative stage compared to using high power lights when plants are too young to use it all anyway. They can also be used to flower plants in spaces that are shorter than what’s possible with other grow lights (aka ‘stealth growing’).

That being said, when it comes to the flowering/budding stage, if you can fit a bigger light you will get significantly better yields/watt by using an HID or LED grow light!

2.) High Intensity Discharge (HID) Grow Lights

HID grow lights are much more efficient than fluorescent lights and are powered by large, oddly-shaped bulbs. They are usually screwed into a reflector or hood to reflect more light down onto the plants. HIDs are great at growing cannabis, but they also get very hot and are usually hooked up to an exhaust to help vent out heat.

(most common grow light combination for cannabis)

Full tutorial on CMH / LEC grow lights
(LEC stands for “Light Emitting Ceramic” and is a type of Metal Halide bulb that is built with ceramic like an HPS – basically it’s sort of like a blend between MH and HPS bulbs)

Metal Halide (MH) Grow Lights

Metal Halide grow lights are generally used for the vegetative stage because they produce a bluish light that vegetative plants love, though this type of light can also be used all the way to harvest.

The light from a Metal Halide appears a little bluish, and is well suited to growing cannabis plants in the vegetative stage

High Pressure Sodium (HPS) Grow Lights

High Pressure Sodium grow lights are often used during the flowering stage because they are very efficient and their yellow light stimulates bud production. HPS grow lights in the flowering stage get better yields per watt of electricity than any other type of grow light available today, which is a big part of why they are so popular.

The light from an HPS appears yellow, and is great for flowering plants because the light spectrum stimulates bud production

Ceramic Metal Halide (CMH) & Light Emitting Ceramic (LEC) Grow Lights

These are actually just two names for the same thing. This type of metal halide bulb uses ceramic as part of the lamp just like an HPS. As a result, CMH bulbs are more efficient than regular MH lights (though still not as efficient as HPS bulbs).

“LEC” and “CMH” both refer to Ceramic Metal Halide grow lights, which is a type of HID light that is a bit more efficient than a regular Metal Halide light

Pros and Cons of HID Grow Lights

  • HIDs are the most efficient type of grow light (gets the highest yields/watt).
  • Of all the HIDs, HPS grow lights are the most efficient and the best for the flowering stage. When using HPS grow lights in the flowering stage, you can expect about 0.5-1 gram/watt if all goes well.
  • HID lights are simple to use because they can be hung the right distance from the plants with no guesswork on your part (unlike LEDs), and no need to adjust the lights all the time (like fluorescents).
  • HID bulbs get really hot and generate a lot of heat. Because of the concentrated heat production, you will almost always want to put the bulb in a hood and also provide some sort of cooling to prevent heat from beaming down onto your plants and driving up the ambient temperature of your tent/grow room. This is especially important for the bigger lights with power above 250W.
  • Additional setup – As a result of the heat mentioned above, most growers use an exhaust fan with ducting to vent out heat. Unfortunately, the prospect of having to deal with the fan and ducting scares off many growers from HID lighting.
  • More parts – HID lighting means a few more parts than other types of lighting. Fluorescents are just the bulb and a fixture and most LEDs are just the light itself. But most HID setups have at least a bulb, fixture, an external ballast and an extra cable if you don’t count the exhaust systems parts, too.

Example of MH/HPS Setups That Yield 1-5 Ounces/Month

  • 1-2 oz per month
  • Electricity: $69/month (including electricity for fans)
  • Initial Setup Cost: $605.00
  • 1.5 – 3.5 oz per month
  • Electricity: $96/month (including electricity for fans)
  • Initial Setup Cost: $744.00
  • 2.5 – 5 oz per month
  • Electricity: $128/month (including electricity for fans)
  • Initial Setup Cost: $780.00

There is a larger size MH/HPS grow light available (1000W), but at that size it starts going outside the scope of a “hobbyist” grower as far as ease and yields. In addition to needing a lot of extra cooling which costs electricity, a 1000W HPS grow light is less efficient compared to a 600W grow light (as far as how much light is put out for electricity used). I think most hobbyist growers would be happier with a 600W, or even two 600W lights, over a 1000W 🙂

HIDs are very well suited to growing cannabis and very easy to use once they’re set up. If your main goal is to get the highest yields possible, then HIDs are the way to go! However, they do require extra setup compared to the other grow lights because chances are you will need a fan to vent out heat from your grow space.

3.) LED Grow Lights

LED grow lights are very popular among cannabis growers as an alternative to HPS grow lights. They tend to run cooler and also usually come with built-in cooling. They can often be plugged into a wall and simply hung over plants which is definitely easier than setting up an HID grow light. LEDs also have great penetration so they don’t need to be moved frequently like fluorescents.

Simply hang an LED light over your plants and start growing!

  • LEDs almost always have built-in cooling that pushes heat up and away from the plants (unlike HID bulbs which beam heat down on your plants and need to be cooled separately). As a result LEDs run very cool and many growers are able to get away without venting heat at all.
  • The smaller size LEDs can be plugged directly into the wall and hung up over your plant, without needing to do anything else. You can just plug them in and start growing!
  • Some growers believe LEDs produce more resinous bud. Combining LEDs with HPS grow lights seems to be getting some growers really great results, though more testing is needed.
  • Although the LED lamp itself usually does run a lot cooler than a similar wattage HPS bulb, they still produce heat and the bigger sizes like 300W+ may need to be vented with an exhaust fan to prevent the grow space from getting too warm.
  • Despite what some sellers may tell you, LEDs get slightly smaller yields per watt than HPS grow lights on average (LEDs commonly yield about 0.5g/watt, though some growers and lamps get better results than others!). There is a learning curve when it comes to getting the best yields from your LEDs, partly because each lamp is different and there are no “standards” to go by yet. A little experience with a specific lamp can improve your yields by a lot!
  • LED grow lights tend to need a lot of space between the lamp and your plants, which means you need a tall grow space to get the best results. This is actually the main thing holding me back from trying LEDs more. Smaller LED panels should be kept 18″ or more away during the second half of the flowering stage to avoid light burning your buds (buds can be burned from too much light even if the temperature is cool), and some of the bigger models need to be kept 30″ or more away from the buds. When in doubt, contact the manufacturer!

If you get very high-wattage LEDs, you may need to vent out heat to keep the grow space cool

For growers who are looking to harvest 1/2 to 1 ounce of cannabis a month, LEDs may be your best choice. At this size, they are super low on electricity, run cool and need almost no setup! They get better yields than fluorescents but don’t run as hot as an HPS of similar wattage.

Note: When shopping for LEDs, make sure they contain some amount of green or white (full spectrum) light. Plants grown without at least a tiny amount of green or white light are very prone to nutrient deficiencies and simply don’t grow as well. Learn more about how light spectrums affect cannabis growth!

Now that you are familiar with all the most common cannabis grow lights I hope your choice is a little easier. I wish I’d had this information when I first started growing indoors 🙂 Happy growing.

There many grow lights that work well for growing cannabis indoors, but they boil down to 3 popular types: fluorescents (CFLs, T5s), HIDs (MH, HPS, LEC) and LEDs. Learn the differences so you can pick the best option for your setup!
