And if you tink a 150 AB will beat a 250 iwasaki
this what I tink

I am French and have read a lot from french board in europe
and there no way you could grow any hight light demand on a
AB 150 HQI in fact they recomend this bulb for SOFTY you dont realy need to be scientific to know this only talk french those guy
run the AB for many years so I tink they know them a lot better than any of us! this not science this THE FACT !!!!!!!!

Anyway Comparing an iwasaki 400 or even a 250 whith an 150 watt 10k is completly usless and you dont need to be a rocket scientist to know that you only need to be a litle bright

the AB is on the market for more than 10 years (im not shure exact time but long time ) just tink about this and if a compagny have found a 150 that light like a 400 all other would have copy it long time ago!! not only for aquarium but all other MH aplication
