I agree with az above, always try to ask before purchase.
I have only ever run A51's RW spectrum and DIY Cree when it comes to LED so I couldn't tell you how those lights perform. As for the price, I have always found illumitex too much for me to consider. Maybe
@FranJan will give you his 2¢, I'm pretty sure he has some of their F3's in his DIY.
Sorry GG I meant king for LEDs. Some people could never run HPS due to heat and stealth restrictions so R/B were and still are better option than most CFL and non HID setups.
