Lighting 350w cheap led

[dragondust]

I bought 350 wat led 128wat draw it's labled as 150 x 3 watt chips of ebay in 2014. I never used it. I current have 2 mars 300w leds.

Here are the pics

Can this be moded with current drivers. There are 3 drivers each powers a bank of 50 leds. Tested voltage under load. It reads 120v dc.

I would like to mod it for white leds.

You could use these drivers, but they are only 300mA so you will get great efficiency if using Cree cobs. You could run 3 cobs per driver, like 30-32W total per driver.

Frankly it's just not worth running 300ma. Defeats the whole purpose of improving your lighting situation. I think the original drivers in my MarsHydro 300w old model(170w version) were at least 700ma.

These drivers have High voltage and not that much current.

Cree cxb 3590 72V on each driver will give about 21 watts per driver.
2x citizen 52 V per driver will give about 30 watts per driver.
Both these cobs are expensive and you may as well invest in new driver.

You can use 4x vero 10 or 4x vero 13 per driver.
Vero 10 are just $3.89 and vero 13 are $6

Thanks for all the answers.

Which vero 10 or 13 should I get and what reflector if any to use. i think i have space 8inch by 12inch to use 8

What size tent you have. If tent height it not tall then you don't need reflectors.
Quality Reflectors Optics are expensive and cost adds up quick if you have too many cobs. If you want good optics... got to use more powerful cobs to make optics cost effective

Either is fine. 13 is little more expensive and has slightly more power and efficiency
BXRC-35E2000-C-2X Vero 13 3500K 80 CRI 32V*4cobs= 128V multiply by 0.3 to get watts per driver
BXRC-35E1000-B-2x Vero 10 3500K 80 CRI 26.5V*4cobs= 106V multiply by 0.3 to get watts per driver
4 cobs per driver * 3 driver = 12 cobs.
Molex Pico-EZmate™ Harness for Bridgelux Vero are not too good. Better to solder

Tent is a 100cmx100cmx200cm. I have 2 mars 300w old 180wat draw leds currently in use. I just want to mod this light for fill and white light for pics and use it when I mod one of my mars 300w to cree.

Boy these Chinese lights just get worse and worse! Its not even them competing anymore, now they are merely praying on the uninformed!

Unfortunately your spot on pop. Go punch in grow led lights on eBay and select actions only. Then count the bids on the first page alone. These companies are praying on new growers or people with limited budgets and doing whatever necessary maximize profits.

YeAH, I do a lot on ebay and I see it all the time. New! Double chip 12,000 watt only uses 128 watts.........
