for a pre-built led fixture?, NONE....it can be around your budget if you DIY........topbin leds/cobs and quality drivers/components are expensive.24"×48"×72" tent. Recommendations for under $300? One light for veg and flower.
Thanks for any help.
I like that bar. It looks like it'll throw a light foot print that matches the shape of my space. Guess I'll pull an extra shift at work.Under 300$ with 2x4 foot CMH is the best.
(Much) more efficient than cheap blurple diode panels.
If you up your budget.
The T3-2100 from Tastyled will do 24*48 really well.

It's 530 dollar
This chip it is very bad. 90-95 lm/watt.This product is bad.Thanks for the feedback! I think I am will running at 1400ma
this is the half made panel that I am going to buy. Its also on alibaba
Have any one heard this company?

Bridgelux v22 almost hits efficiency of the Vero 29. $15 each.Look into Vero 29. Anything lower priced than that is probably waste of money. Maybe Vero 18....

Honestly for that budget, a 600 watt hps is going to do better than anything else. For about double your budget you could go cob. But you could get a 600 watt setup for less than $150. And 600s are pretty efficient as far as production lights go. Not as good as DIY or high quality LEDs, but none of those fit the bill/budget.24"×48"×72" tent. Recommendations for under $300?

If I can cut the heat output I'll be able to grow straight through the summer without A/C. It's a San Francisco, ocean coast type climate. But does get in the 80's in July and August. I run led lights at night and off during the warm part of the day I'll be good.Honestly for that budget, a 600 watt hps is going to do better than anything else.

I'm down in la. So similar, but usually warmer. I've never had a problem with a 600 and a 6" inline fan as far as heat goes. Low efficiency LEDs put out just as much or more heat if you have the same wattage output. But if you've got like $500-700 you could totally do led that would cut your heat and electrical output.If I can cut the heat output I'll be able to grow straight through the summer without A/C.

If my budget wasn't practical, then I need to readjust. It is what it is.
Do you have an efficiency spreadsheet for V22?Bridgelux v22 almost hits efficiency of the Vero 29. $15 each.
Vero 18s at 500ma are ~48% efficient. So you can run a lot more of them at a lower current with a better footprint. Won't touch the efficiency of the 3590s but either option is a huge upgrade from hid or Chinese box LEDs.

Does it take the same cob holders like the crees? Do you know if Supra has done a spreadsheet for this one? Thanks!
No I think this one flew under the radar as its bridgeluxs budget cob series they don't really advertise it. The veros are more expensive for less efficiency and are kind of their flagship ATM, but they do come with holders. Which I don't use so they do me no good anyway. I'd assume the 2 piece plastic holders that go on the corners of he cobs would work. They're about the same size as 3070s.Does it take the same cob holders like the crees?
