This LED worth a shit?

I know fuck all about LEDs, but I picked one of these up in a bundle of gear last month for about $100, no noticeable wear, works fine...

Only looking to veg with it, maybe toss some lettuce/potatoes too, but use HPS+CMH to flower...

Nope not a good light but for $100 not too bad it will veg

Seems like it might be decent, but manufacturer doesn't list efficiency on their website AFAICT. $600 for a 150w light, it better be efficient. You could contact TotalGrow and ask for radiometric efficiency data. And/or flower it out in a 2x2 area and see what the yield is.

He could probably put some t5s or t8s on each side of it for veg.

bah, screw that. I got 400/600 MH currently for veg, if this is just stepping down, ill toss it on the yard sale pile....

It may be worth testing out.

Seems like it might be a decent light... but it is only a 155w lamp.

1,55μMol/j seems not very impressive compared to a quantumboard with 2,4μMol/j.
@Rahz It's actually only 143w, Lol!

Well, there you go. Nice research.

Not impressive, but not terrible either. I'd mount it above my workbench if it wasn't pink. Those emitter housings... looks like they might be blocking some of the light for the sake of uniformity. Not sure what's going on there.

Yeah, they look a bit strange with their zylindrical shape and sidewise mounted phosphor layer. First time I see such lenses...

I didn't see anything with the temperature of the light, but looking at the spectrum chart, I am assuming 5K or so... might work OK for veg. I would rip out the lenses though. They are likely reducing lumens more than they are helping.

It looks like the lens has a sourrounding yellow phosphor layer and underneath is a royal blue diode, something like "remote phosphor" but in a relatively small way.
One can buy remote phosphor disks in different shapes and spectrums to convert royalblue into broadband white.
If they were to use the most efficient 450nm XP-G3's, they would probably not be far from 2,4μmol/s.
You could also make your own phosphor mix and make your own disc, lens or what ever. The ingredients are available on Alibaba. Basically, there are 3-4 ingredients that you can get relatively cheap.
I would like to see which diode is used below these strange phosphor coated lenses.

One should try to get only a bunch of the lenses and combine them with the best available blue XPG3 (730mW/2.78μmol/j). The system efficiency would be much better!
