Thank you!

So that's not watts drawn from the wall, the ac side? It's the watts on the dc side?

Even on 6 cob's? Or did I misunderstand what LED multiple means?

I'm at the cree product characterization tool. I've attached a screenshot and I'd like to know what the circled value means. "LED W". Any help?

I REALLY should've gone kettle corn. I hate when I do that! :clap:

Nice! What's the difference between elg and hlg drivers??

You mean lenses not reflectors right?

I've read that lenses degrade light output by like 3% ish but it seems to me that not using them might also degrade output because of increased light dispersion. Seems lenses would focus the light better than without thus making up for a small output loss? Do you use reflectors with your lenses?

Right ( not that I knew that ) but isn't it the case that is the full potential watts of each cob ( power draw ) is dependent on how it's driven? Wouldn't a 50w cob dimmed 50% be 25w effectively?

Ok so it's the watts of the driver, in this case just slightly under 250, ÷ by the number of cob's is how you're coming up with 49.8w per cob? I know I'm focusing on watts here but bear with me... Because 5 cob's is the most this driver can "fit" as far as efficientcy is concerned, (I hope I...

The titanium nitride...you mean drill bits?

Awesome! I'm interested in how the drill press works as I'm thinking of getting one myself. Good luck drilling!

Hey AW, I know you're a fan of self tapping screws. Do you need to drill a pilot hole the same length and size of the screw? I know that sounds dumb probably but... Thought I'd ask.

Dude! I've got a 20% off coupon for hf! Lol I've heard mixed reviews about it. Does it seem will made?

Man gg... Thank you!

What are the dimensions of you heat sinks? How many lumens per square foot? Nice build!

How does the driver change affect your ppfd and wattage or does it?

How do you equate that your 200w cob light is a replacement, results wise, for a 400w HID? Nice build a good info. I'm just a little torn about my build. I want to replace a 400w HID with a cob light. Greengenes says 5 3070's on an hlg 240-1400 but I was never clear that would replace the...

Would anyone have a link to a solid, cob build that would replace a 400w HID? Or suggestions? I'd like to use 3070's bb bin.

Yeah I researched those too. On paper they look pretty good. Best of luck! ;-)
