This indoor grow kit is designed to make purchasing and setting-up your own DIY LED grow light simple. The MakersLED heat sink design is an excellent choice for grow applications, it easily mounts or hangs, has a rugged design and fan to help dissipate heat and the t-slots provide a perfect way to secure the LED board.  The printed LED circuit board(s) that the kit comes with has a total of 30 multi-spectrum LEDs per board.  It is custom designed for the MakersLED and the LEDs have been placed in specific locations to make connections solderless and mix the wavelengths up evenly.  The LED board includes screw-in terminal jacks for fast connections to power and holes for securing the board to the heatsink as well as holes for mounting secondary lenses to focus the light. To help with the planning and building process, we include a wiring schematic and step-by-step instructions as well as a video tutorial; basically everything you need to have a high-quality, working, long-lasting indoor LED grow light. Below is a complete list of the product IDs that are included so if you wish to research the components and their capabilities you can.

LED Board Configuration
Color Wavelength Qty
Far Red 740nm 2
Photo Red 660nm 10
Red 630nm 8
Royal Blue 450nm 6
Warm White 3000K 4


Simulating natural sunlight should be the objective of any grow light, which is what we considered when picking the array used here. A formal list is below in the chart: we used Far Red (740nm), Photo Red or Deep Reed (660nm), Red (630nm), Royal Blue (450nm) and Warm-White (covers the entire spectrum, but peaks around 450nm and 660nm).

Each board has 5 channels of LEDs; each channel has a total of 6 LEDs in-series, making a total of 30 LEDs per board. The center row is Royal-Blue, the surrounding rows are mixed with Red and white and the two outside rows are Photo Red and Far Red.


This LED grow kit is scalable, because every plant and every grow set-up is different we offer different length, which allows for more grow boards on one heat sink. The standard lengths are in increments of 10-inches up to 40-inches. A 10-inch kit would include 1 grow board, a 20-Inch kit would include 2 LED boards and a 40-inch kit would include 4 grow boards.


Grow lights are commonly categorized by wattage. But, because LEDs are more efficient that older grow light technologies, you can't compare LED wattage with Metal-Halide (MH) or High Intensity Discharge (HID). We consider a 100-watt LED light to be equivalent to a 200-watt MH or HID. Using low voltage LEDs, in addition to saving energy, also are much safer and cooler than the MH or HID. This significanly lowers costs and helps keep your grow area from getting too hot.

Controller Option

Besides deciding how much light/wattage/coverage you need for your plants. We also offer a controller with this grow kit that allows you to easily set the time-of-day and control when the light turns on and off. The controller also can ramp up and ramp down the light at the beginning and end of the day to simulate sunrise and sunset. We like this feature as it simulate the natural environment. The controller has other features as well, which can allow you to control light output of each channel individually and create moonlight, cloud cover and lightning storms.

Excellent first LED project kit
Greetings all. I bought this kit, and I'm sure if you are reading the reviews then you may be in the same situation I was in. I was looking to build a LED light to grow vegetables indoors. I don't have any knowledge in lighting technology (I've never used any HID), but from everything I read LED seems to have proven itself as a viable lower cost option than HID, and better (maybe) than CFL. The only thing I really knew is that the shop lights you see in Lowe's are not what you want to use to grow, mainly because they are made to output light in wavelengths that look good to humans, not to plants needing to photosynthesize, mainly blues and reds. The first problem was I could not find any place that described the various components needed, and how to assemble them into a working light. I stumbled upon a link to this kit, so I thought it might be wise to just buy it, and by putting it together I would gain an understanding of how it works, so in the future I may be able to cut out some cost by buying the LED's and drivers separately. I will start by saying this kit is 100% legit, seems to be top quality components, contains 100% of the parts you will need to build a working light, and has lived up to my expectations. I have three varieties of tomatoes (yes, really tomatoes), and in only a few days after popping above the soil after germination, they are a few inches tall. I can literally notice growth every day. You will not be disappointed with this light as it fired right up the first time I plugged it in after wiring. Now, there is one caveat, and one that could prove daunting for the less inclined; the instructions are extremely inadequate, as there were literally only a few lines of stuff like "wire all the drivers", or "connect the thingy", or something to that effect. Also, the wiring schematic shows one lead of two of the drivers needing to be jumped to two connections on the board. The instructions said nothing about having to do this, but I have a little experience with engineering diagrams, so I was able to figure it out. All told, it took about three hours to fully put it together, and my tomatoes and peppers are very happy. Hopefully I will be too once I eat my first batch of GMO free homemade salsa.

New Design
I love the new design of this kit. I've been looking at purchasing this kit for a while now and I'm glad I waited. The populated LED board makes things much easier. No mounting individual stars! No soldering! I feel much more comfortable about being able to handle building this kit myself now. Great change!

Perfect DIY Kit
I built mine in a few hours, but it was only the 1-foot version. So far I have produced quite a yield with these LEDs. The grow technique i am using is sea of green with some lst and super cropping. One of the benefits besides the obvious lower electric bill and long lifetime, is the the low amount of heat. The lower heat output is keeping my grow environment at the perfect temperature both day and night. I learned though that with these LEDs you can keep the light much closer to your plants then an HID. I opted for no led optics on my lights, but I'm thinking of adding them to increase the intensity of light. Worth a try since the optics are pretty cheap. The heatsink grow kit isn't cheap, but is very sturdy, made here in the usa and comes with top-of-the-line components. For me this was worth it. Why spend less and get less! 5 star recommendation from me.

If interested check out...
There is a DIY project that someone did with the MakersLED for a grow light on this site. Click on the DIY tab in the main menu and you'll see it. I called after viewing that project to get more info, but that post showed quite a bit. It is a big project, but if you follow the grasscity thread you'll see that their customer had pretty good results with this light. The LEDs are from Cree and Luxeon, two of the best LED manufactures in the industry. And, the heatsink is perfect to dissipate all the heat created. I am going to buy a couple 2' kits for my grow room. I'll check back after to let everyone know how it turned out!

Everything you need
Great Kit!

I have been pouring through the internet for a long time looking for a good quality LED grow light that doesn't cost a fortune, without much success. I was a little hesitant about building my own, but this kit makes it easy. The kit comes with the right number and color of LEDs, plus the heat sink, drivers, power supplies - even fans and a lexan cover. I did have some questions regarding how to wire things up. I called LEDSupply and a tech. there answered all of my questions. I definitely recommend this kit!


What does the MakersLED Kit include?

  • cut to length heat sink
  • matching length splash guard
  • two plastic end caps
  • four t-slot plugs
  • 92mm fan 12V [one per 12”]
  • custom 92mm fan bezel [one per 12”]
  • stainless steel assembly hardware (exposed parts)
  • 4-40 bolts and nuts, enough for 25 LED’s [per 12”]
  • nylon washers, enough for 25 LED’s [per 12”]
  • MakersLED Kit Components

    What are the dimensions of the fixture?

  • Height: 3.15in
  • Width: 6.45in
  • Length: 1ft Increments
  • Acrylic: 5.9
  • Lanes of LEDs: 5
  • MakersLED Dimensions


    How many LEDs can be mounted to a 12 inch MakersLED?

    Over 30 LED stars can be quickly mounted, repositioned, and upgraded within a 12” length of fixture.

    MakersLED LED Placement


    Why are there so many slots for the splash guard?

    Lenses come in all heights and the multiple slots allow the splash guard to keep close to the lenses. Depending on lens height, the splash guard may help hold the lenses onto the LED’s.

    The additional slots could also allow for printed circuit boards (PCBs) to be slid into the fixture for power inlets, interconnects, or LED drivers.

    One could also design a custom piece of opaque acrylic with holes for your LEDs to illuminate through if you wanted to cover up wiring (shown below). Ponoko and Pololu both offer affordable acrylic laser cutting services. Inkscape is free software which you can design the artwork in.

    In most cases, when the LEDs are turned on, they will be so bright you won’t be able to see the underside even when you are looking! The built in t-slots also offer a great place to tuck your wires into for a clean look. Long lengths of extrusion also help hide wires.

    MakersLED Acrylic Lens


    What material is the MakersLED made from?

    MakersLED is made of heat sink grade 6063 aluminum. Plastic parts are made of ABS plastic.


    What type of fan is included?

    The fan is a standard 92mm x 25mm fan. Any fan with these dimensions will also work. It is a 12VDC fan.

    MakersLED Fan


    How is the fan powered?

    We recommend purchasing an AC to DC power adapter with a 4-pin molex PC power connector, however any 12v DC power source with enough amperage will work.


    What type of LED’s can be used with the housing?

    Just about any LED can be used with the MakersLED fixture. Even though the T-slots are based upon 20mm stars, many other sizes and designs can be used. Larger LED boards and triple diode ‘pucks’ can be turned and bolted down at angles. Strip style LED’s can be mounted in virtually any direction, parallel, perpendicular, or at angles.


    Do I have to solder my LED’s?

    No, soldering is not necessarily needed. There are a number of plug and play or friction fit electrical connections to the LEDs. However, soldering can be easily mastered and is the recommended connection. We will offer information on an inexpensive soldering iron and a how-to video describing this process. It really is easy!


    Is thermal paste needed?

    Yes. We strongly suggest using thermal paste or thermal grease to effectively dissipate heat from your LED’s. Heat will deteriorate your LED’s, decreasing light output and longevity.

    Using less thermal paste is better than using too much. The thermal paste’s job is to fill in the minute imperfections of the two surfaces. Standing air is a bad thermal conductor. Aluminum to aluminum contact will almost always outperform thermal paste.


    Why use T-slots for mounting LED’s when there are alternatives, such as double stick thermal pads and tapes?

    We do not recommend using double stick thermal pads and tapes because of their poor thermal performance. In addition, the T-slots offer a clear advantage because of their ease of use and ability to reconfigure LED locations at any time.
