I believe I once read that North/American bulbs were good for probe/electronic but the German etc are pulse electronic only. Hopefully someone can help you!

Sounds like an interesting bulb though. If I read the info properly, are they implying that it could have the PAR rating of a 10k with 13k blue look?

Neat!

I have those exact bulbs on my tank. I am running them with an icecap ballast.

just found a site that has tested them on a m57, so obviously they work on a standard ballast..

woot! :mrgreen: :mrgreen: :mrgreen:

and oddly enough, after 3200 hours the output(ppfd) went from 51.8 to 50.8, but the cct dropped from 9269 to 8442. output hardly dropped, but the color shifted quite a bit...actually, shifted to what most 10000k bulbs are...go figure.

I like this bulb. time to buy one

They are really yellow on a standard ballast just so you know. :biggrin:

the 175s or 250s? ;)

it is a probe start, but still using a pulse start ballast will give you better color, and longer life.
