Yeah I'll stick with my Iwasaki 6500K lamps supplemented with the VHO actinics.

I get the intensity, the full spectrum, the asthetic appeal, and the best bang for the buck considering the lamps are WAY cheaper than the higher K counterparts.

Anyone know who the maker is for the 10,000K 175watt bulbs that Hamilton distributes?

I use the 400 watt Iwasaki and I like it. How much do a set of VHO's run you usually? Anyone out there got any used ones for sale? Im gonna post in the buy/sell :D

<font size="2" face="Verdana, Helvetica, sans-serif">Back in the day when I was using 175w, 10kk bulbs, all hamilton bulbs were mannufacturered by Ushio, a Japanese company. The reason that Hamilton claimed the bulbs were Geman because the plant that produced the bulbs was in German.

Good find StirCrazy! I'm even happier with my 250w Iwasaki now :D Too bad there's no info on the 175w Coralife bulb though. I'm kind of curious to see how crappy my old Coralife really was.

hehe, personaly I am interested in seing how the 150 watt DE HQI (german) that J&L is selling would stack up agains the AB's.. I have found the AB's but they will cost me about 180.00 to get the ones J&L have (the Ushio)

I am wondering because if it is even only close to the 250 wattt iwasaki instead of the 400 watt like the AB version for 10 bucks mor eit would be worth it to have the 10000K colour temp.

another interesting thing has poped up.
seams that in order to show that the 150w 10K AB DE HQI are as bright as they clame, he put one in a pfo fixture and also put a 250w 10K Ushio Mogul in the same fixture and took a pic side by side.

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.

Stephan, you posted this on the other thread and the Germans said they use this bulbs for SPS on up to 24" deep tanks did you miss that? or do you not believe the Germans over the French? :D

That pic is not really a good one as the 150 is in an inferior pendant. If you look at the other pic they are in identical pendants.

Besides I am only comparing them to a 250watt bulb here... so don't turn this thread into a RC argument... I have not claimed here that the AB is a good of lights and everything I have posted has been factual and standardized... not the result of a half assed visual light test with to totaly different fixtures / reflectors. Personally I don't care what anyone uses for lights I just thought people would want to see some hard and fast #'s that were collected in a scientific and standardized method.
