Did the numbers on LED lighting conversion at a local old building homeless shelter.
100w incandescent light bulb 4hr/day x 30 days @ 10¢/kWh = $1.20/month
14w LED bulb (100w equivalent) 4hr/day x 30 days @ 10¢/kWh = $.17/month (+ $1 bulb = $1.17 1st month)

Ordered up 50x 50w "Full Spectrum" grow LEDs (New York State legalizing recreational Marijuana, so.
Each individual will be allowed to grow their own 6 plants, 12 per household. For better quality-quantity harvest, controlled environment will be essential!)
Stocked up on the 110V COB (Circuit On Board) modules. These Aluminum bonded modules do require heatsinking. Ideal were the old, heavy 4' florescent shop lights, pop riveted 2 modules per, with conductive grease between. I will be supplying power with 22ga solid wire and am considering placing 1Amp fuse in line for every module (50w/110Vac= .45A).

Previous module experience include:
12V 30w LED modules attached to P3 heatsink-fans;
110V 3x 30w modules attached to 4' old-bare florescent fixtures (old style, thick metal with angled reflector)
110V 2x 50w modules attached to 4' old-bare florescent fixtures
Most ambitious (but now obsolete technology) project involved running 1x10w(11v 1A)+12V fan - 1x30w(36V 1A) - 1x30w(36V 1A) - 1x30w(36V 1A) - 1x10w(11v 1A)+12V fan in series from 110VAC through a bridge rectifier (modules 2" through screwed to 2"x2" aluminum square tube with fans supplying through ventilation
 
The Full Spectrum modules have Circuit On Board (COB) allowing direct 110VAC (or 220VAC). Typically in 20w, 30w, 50w values. (typical 100w modules are only in 220V)

Although available in multiple color temperatures, warm white (3000-3200K), natural light (4000k), cool white (6000-6500K) and beyond 10,000K +, the Full Spectrum are designed for most efficient plant growth.

I love demonstrating that healthy plants appear black under "Full Spectrum" LED light, everything adsorbed, no reflected-wasted green or yellow light!
 
Bare 110V soldered connections are not recommended!
I have variously shielded with hot melt glue or silicone, for an enhanced solution there are alternatives.

#1 - quick connect, strip and insert wires (coat or cover alternate L + N solder points)

#2 - Protective, and waterproof, lens-cover

Received:
50x 50w Full Spectrum grow lights
100' 22ga non-stranded copper wire
200x 250V 1A fuses



I intend on individually fusing each 50w module, will "in-line" fuse but cover-insulate with clear heat-shrink tubing. Proper operation will task fuse at ~40% rating.

Following to learn. I’ve a bunch of new 18650 cells. I’d like to build out my own solar charged yard lights. Ideas?
 
Availability dictates "12V LED" modules and solar panels.

1 set of budget modules.


Also do an ebay search for "12V flood"(wide beam), or "12V spot" (narrow beam), for pre-made units (typically designed for vehicles).
Don't forget "3s BMS"s.
"12V solar panels".
