3x $3.99 packs of 10 plastic light bulb sockets (ebay)= $12
32 LED light bulbs (amazon) = $30ish
Scrap piece of MDF (lowes or etc)= $4
Some wire = $4
Some solder and electrical tape = $2
Total cost of 272 watt LED grow light = ~$50
I left the globes on the outer four lights for now until I get it hung up. This is my second DIY LED "quantum" setup. The previous one was only 204 watts (24 bulbs). You can get 24-packs of the Sylvania 8.5w 2700k on amazon for less than a dollar per bulb. This one is made of mostly those but some other, older bulbs I had laying around. I had some daylight (5000k) bulbs to mix in as well. I drilled 1" holes behind each bulb holder for the wiring and used solid core wiring to the bulbs and 14 gauge stranded wire (because that's what I have on hand) for tying them together in parallel.
