I am using viparspectra Led 600watt from Ebay Cant fault the light and the warranty is excellent,the after service should any thing happen is second to none, I am uk Based and they ship all over the world.
look them up on Ebay good look.
They're actually less expensive then most after the 25%+ discount. 5yr warranty too.
Realstyles n Timber got nice lights too!
Interested in seeing how the Chilleds work out.
I like Fluence Bioengineering too. Don't get to see many grows w/ them but Im sure they do well.
Go for quality parts, trusted comp. & proven results.
