Can i use 42,02 Wpsf ? (HLG-185H-42B) is it over lighted? has it the benefit of giving more light without CO2? or girls will have light stress?

Thank you for all the advice. Becouse i must change dimension of space dimension from 2x2 to 4x1. I order 6x BXEB-L1190U-30E3000-C-C3 - 80CRI (90CRI is unvalibele) 1,19m 38,2V After first run I will give extra deep red and far red - ratio 2/1. Now i need order driver from local shop. It is...

2700k 90cri it was only for comparable - VERO vs EB vs Vest. because the vest strips does not have 3000k and and EB it is not possible buy 90cri. it was to explain the exclusion Vest strip.

Rocket Soul - you're right. I forgot the coolers. All same parametr. 2700k 90CRI Around 140W complet. Vero 29C 35W from graph can hit 160lm/W - Price is 4x26usd + alpine 4x 11usd. - Complet 22400lm - 148 usd (Passive cooling) EB GEN3 13,4W 156lm/W - 11x 8,64 usd + aluminuim plate 11x 1usd...

Vero 29 C 2700k CRI 90 - 76.7 W Have 143lm/W Vesta strips 2700k CRI 90 - 24.8W - 129ml/W (3x) Price is 26 usd VS 30 usd. Look Vero29C is 10% more effective and 15% usd cheaper like Vesta strips. Where i make mistake?

Now I look only in to vesta strips datasheet. In forum find only effiency as like EBGgen2 series. Isn't the third series better?

Thaks. But i need something from eu or china. I'm looking for the most effective option, Now I have 4x CXB3599 CD 36v total 140W and I have always 1,25-1,4 GPW. I wont make some better light for this space.

Thank you for you ansver. Yes i need second light for same space 2x2. What is better choise? 14x EBstrip Gen3 3000k 80cri - BXEB-L0590U-30G1500-C-C3 (90cri out of stock) 10W each / 140W or 4 vero 29 C 3000K 90CRI. 37 35W ech / 140W Tent is DIY 2x2x5. height is not problem.

What should I buy for same space build? Again 4X CXB3590? 4 Vero 29 C is not better? (run at 35W) Thx

I found this thread - COB efficiency Spreadsheets https://www.rollitup.org/attachments/cxb-3500k-png.3486878/ At 700ma - 207 lm/w At 1400ma - 182 lm/w 190 lm/w is between.

Hello. I have 4X CXB3590 CD 36V runing at 36W in 2x2 space (36W/psqf) - 194lm/W info from forum. a friend wants to make it same from my. And I have 2 option. Option 1: Sell this light and make new one for me more efficiency. 4X Vero 29 C 3000k CRI90 (BXRC-30G10K0-C-7X ) Run realy low- 35W per...

Thx for answer. i found only this picture with alpine11. (no in stock in our country) And looks that COB not fully fit.

I can not find Cpu cooler which fully fit for vero 29. Alpine 64 GT and 64pro is not flat. Have you some experience wit somethil else like 64plus?

In my country alpine 64plus stop selling. Last time i use this. Work perfect. Can you please recomend some other which one fit for vero29 with 70w? Can i use alpine 64pro? But It is not flat. Thx

Hi please look to rapidled to emerson-effect-booster-board Spec. 12 x photo Red (around 22w) 6 x far red LEDs (around 8W) Coverage Area : 2' X 4' Current 700mA 15min after light. Why use photo red? Why not only deep red? Is it 8w deep red to cover 2x4 enought? Thx

Thx for answer. I did not write. i have in home 2psc vero29 g7 D version 3000k and 2 passive heatsink. only what i need is some driver. but what is the best? :-D
