I would like to put your SP250 light ,in a 4ft by 4ft tent, alongside 250w of strips and we could see direct results , between the two lights. I expect kinda the same result from both lights, but i would need to see.
Anyway hopefully we’ll see what your lights can do soon 
. I know you have more expensive lights, how much does your ‘best’ light cover and at what wattage/price etc…
And before, when i asked you about your cobs- what i meant was does every cob light NEED diy or does @Zoey make a ‘pay&play’ cobs too .!?
You thought i was asking you if you can wire a cob… haha.).
