Hi chums, I've built a couple of my own lights, a 16 COB CXB 3590, and a 16 COB Vero 29. They've cost me a fortune and are performing really well. If I want to build up lighting for another area (primarily for vegging), is there any possibility that these could really deliver 140 lumens/Watt? (like it says in the blurb). http://www.botanicaled.com/index.php?m=content&c=index&a=show&catid=125&id=149 They are so cheap that another 20% efficiency would not seem all that relevant, but if they are likely to only hit 100 lm/W, I might as well use LED household globes with the tops popped off. What do you think?
