thanks

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.

how's this?

[Invigor]

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

woot!

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.

the 175s or 250s?
