G.O. Daze it would stand to reason that 130 watts would not get as hot as a 400 watt bulb but the 400 watt bulb puts out close to 40,000 lumens and your two floods only output 9,000. I know you say the plants grew as fast as 400 watt but that is just not true. There is science behind the photosynthesis process and given equal circumstances the floods do not promote the same amount of vegetative growth as a 400 watt HID...It just can't happen.
Sounds like you were satisfied so that is good.
