Europen reefer who utilize this bulb for many years refer the 150 AB as a softies bulb and they have tested it for about 10 years
So people be aware before trow that money on someting like this
Here is a quote of the original start tread from
a guy who I have talk several time and he have a goog knowlege IMO:
The 400w is an Ushio in a PFO pendant driven by a PFO standard ballast. Bulb is about 4 months old. I am currently seeking an HQI ballast to run the 400w on so it will be even brighter (about 10%).
The 150w is an AB aquastarlight with a 6mo old 10KK AB bulb.
This really does put a nail in the coffin for those who are jumping on the 150w bandwagon expecting close to 400w intensities. Both pendants have a white paper towel under them to hopefully capture some color difference as well as display what is reflecting off.
Here are some pictures. You make your own decision.
