Are you in MA?
I've got 8 x Vero SE Ds - the 36V version. If you need some help getting started
or even just want to see what X watts of top-bin LEDs look like in-person before taking a leap, I'd be happy to give you a demo.
Mine aren't as potent as the fixture you're proposing but, I'll bring the Kill-a-Watt... and you'll know right away when you see
600W on the meter and how ridiculous that amount of light is.
As long as your inside 495...
Also, I know I'm a broken record with this, but Citi COBs, for the price, cannot be beat. COBKITS.com, has the
1212 Gen 5 for like 9 bucks.
But in the higher-output range, the
CLU048-1818 90CRI (more like $24) can be driven to ~250W and peaks at 630 and looks good thru 680, really.
Check that link... it's one of the things I really like about COBKITs... he's got exactly what we -
at least what I want to see - all right there, at a glance. kid.
Let me know about that utha thing.
