Hi i have a 11sq ft grow space.I replaced my 400w hps with hlg rspec 260w,but it came with meanwell elg-240-c2100a-3y driver with max 230w.As far as i know you should have about 28-35w per sq ft for hlg qb288. My question is would replacing the driver be worth it or should i get 1 more hlg260w...

Yea i was going to buy the china qb but just didnt want to deal with the returns if something broke.Any way here are the two drivers but i dont know what is the difrence other then the price...

Dont think that what it means since my driver is also dimmable but the wierd thing is that the dim switch is at the bottom of the driver not on the top like yours.

Wow nice setup so the Mean Well HLG-240H and Meanwell ELG-240-C2100A-3Y are there same drivers in terms of power?Then why does the HLG main site and Todogrowled site have writen that the light max power is 285watts when it only 230 watts.

HI guys yesterday i bought a watts meter for my 260w HLG RSPEC it said it dimmable from 135-285 watts on Todogrowled site.I tested my light and it only goes from 85-230 watts. What i didn't see,is that in there description of the light on there site,it says the kit includes Mean Well HLG-240H...

Ok good was worried a bit,had the light running for 2h now and it runs a lot cooler then my hps.Plus i had the light working in 30 min with no problems.Now just need to wait 4 months to see how it does vs my old light.

HI again today my 260W HLG RSPEC lights came and everything works except there were a few not very deep scratches on my heatsink would that be a problem.Should i use thermal paste or is it fine .Other than those scratches i am very happy with the light is a very bright vs my 400w hps.

It looks like you all and me like the 2 HLG260W RSPEC with dim more then 1 elite.So my plan now is to buy one HLG260W to test the light and by what i know it should do great,then buy one more HLG260W RSPEC and this lights will still be good in a 4x4 if i buy one in the future .Thank you all for...

yea that a great light but what i want is a light that close to 1000 ppf with the best coverage for 1m2 and the shops need to be in EU or i have to pay about 200usd in tax and shipping just to get the lights from USA. From what i understand anything above 1000PFF i need co2 so my option...

Okey so if you need 30-50W/Sq.ft my grow tent is 1m2 or 9 feet and 4 inches so one 260W would be 27.5W/Sq.ft and two 55W/Sq.ft i could dim the light to 470W and then it would be 50W/Sq.ft.The other option i have is to get the ELITE 360 that 38W/Sq.ft but the coverage is not as good as the 2...

Hi i am thinking of buying a new light for my 1m x 1m x 2m grow tent with 400w hps light.I was going to buy HLG 260W RSPEC one of them for now and one more latter.Would 2 of the HLG 260W RSPEC be to much for my tent size if so should i get 1 Elite 360 led or some different setup?
