250w SE MH bulbs

[caseymou]

Probably driving over this weekend for a bulb purchase but still haven't decided which to buy. I'm looking in the $60 range for 10k's so choices are XM10k, Coralvue/reeflux 10k, or hammy true 10k. I believe these are all priced about the same. Which is most popular? Suggestions? I like ice white, bright, possibly a hint of blue. No yellow.

Thanks,
Chuck

Chuck,

I've got reeflux 10ks on my tank if you would like to stop by and see them. I ran XMs for about 6 months, very white but coral colors lacked. The Reeflux is more white with hint of pink/blue. Bryan runs reeflux bulbs on his tanks at extreme aquarium. I have a 6 month old XM and a 3 month old reeflux if you'd like to try them out before buying one.

how is the brightness as compared to the XM? XM par is really fantastic.

 

[eckrynock]

Yes, XM is really bright. Reeflux are a little dimmer but not much. I think you would be pleased with the color of the Reeflux bulb. I was willing to give up PPFD for color. Coral growth is still decent. I bought an acro from extreme 2 months ago and it's doubled in size.

A lot of it has to do with the ballast you will be driving it off of, however for something that is crisp ice white I would recommend the 10k Reeflux, as you get decent growth and excellent coloration with it.

Are you supplementing with any actinic?

 

[caseymou]

Yup, I use 2x110 vho for actinic although they are way past due for replacement too. I run my 250's from IC ballasts.

I agree on the reeflux. They've been very popular, and the vast majority of people I've talked to love the color. They also have a better quality record than XM.
