How to Make Your Own High Quality Led Grow Light – Part 4

Wiring the Light

In this video I wire up the light and test it. It is very bright! I cover the following:

  1. Wiring the circuit boards.
  2. Mounting the power supply, including allowing for ventilation.
  3. Connecting the power supply to the leds, including different methods of actually connecting the wires together.
  4. Connecting the mains cable and providing stress relief for safety.

By the end of the video the light is complete and ready to go, but there will be one more video where I add some extras like a standard (same type as used on PC´s) detachable power cable and DAISY CHAINING capability and a plug and socket where the power supply attaches to the leds. To do these things I will be using 3D printed parts.

I will also be offering the light for sale at below cost if anyone wants a great quality, low cost light!

Assembling the Light

In this video I cover the following:

  1. Arranging the led circuit boards for the most even coverage of the grow area.
  2. Marking the heat sink for drilling the retaining holes.
  3. Drilling and de-burring the holes.
  4. Applying the heat sink compound to get good heat transfer.
  5. Types of bolts/nuts for attaching the circuit boards, including how to lock normal nuts in place so they wont work loose over time.
  6. Advice on soldering to MCPCB´s including tip types and technique (its different than with normal PCB´s)

Sorry for the delay in getting this up, the holidays and a bad case of flu meant it took longer than planned.

It turned out to be quite long at about 40 minutes, so I have split into 2 parts.

Watch to the very end to meet my lovely production assistant!

DIY Reflow Soldering

In video 2 of the series on making your own DIY led grow light I show how to apply the solder paste to the MCPCB and then reflow the leds using a toaster oven.

For those viewers who found this searching for just information on reflow soldering at home, you should find this useful as it gives a good idea of how to do any project that involves reflow soldering and SMD components. It was intended as a general guide as well as for this particular project. Hope it helps someone!.

In video 3 we will assemble all the parts into a fully functional 80 watt grow light. If you don’t want to make your own light, buy one from us!
