There are a few with different smd chips (5730, 5050, 7020, 5630), but all seem to be 6 watts 12 volts.
So I am thinking a half meter square panel made of these would be
50cm / 1.1cm wide per bar = 45.45 so keeping it even lets say 46 units.
46 x 6 watts = 276 watts
Most PC PSUs have a 12 volt 20 amp rail which should about work and most people have one or two floating around. So free. OR I suppose a 12 volt 20 or 3x 10 amp supply on ebay would be about $30-40 (I think, can anyone find the best $$ driver for these?)

Cost $: say we buy 6x10 packs (30 warm, 30 bright) for a little fault tolerance (assuming some defective strips) and we are looking at $54 USD. Amber says Whaaatt?

Mount them on a metal sheet or make a rail or frame of some sort and the driver would be extras, but seems almost too cheap. What am I missing? Thats like $0.20 / watt right? I am a bit high and none of this is making sense right now so I fully expect that I have missed some critical consideration here. lol

I guess around 40+ lumens per smd (3750), x 39 smds per bar, so a top end of about 70K Lumens for a half meter square panel? (20" sq)

These look even more interesting - 30, one meter long 72 LED strips, with aluminum shell for $88:

A 400+ watt light, all you need is to do frame them and add power supplies - like you said a PC power supply would run them pretty good..

yeah , they are nice at 176-212 lm/w
which also means my calculations have to be way off, anyone know the lm/w rating of a 5630/5730 SMD?
It has got to be about 100 right?
Depends on the manufacturer and series. It could be anywhere from 90's to 140's

so at minimum 90 x 276 = 24,840 lm
good for veg, look sealed or at least water resistant, 80 lumen/watt. $0.50/watt, interesting, I wonder how they are for heat.

I have those from mufue technology on alibaba real nice folks help you make best decision
I have like 50ft of blurple 5050 ive been using. Just put together a new veg cab waiting on my alum heat sink to come in sunday and put together a 100w led light. Get rid of these fkn cfls lol
