I gess I should look at upgrading my bulbs... Anyway I was looking for a way to justify changing to 14K or 20K

I've been having trouble with mine as well, I have a 250w, after about a month of use the bulb burned out, I got a replacement, that lasted 2 weeks and it did the same thing. Now I have gotten a replacement ballast, as that was supposed to remedy the problem, but it didnt change anything. So I have been without MH for almost 3 weeks now.

It realy surprises me that companies can get away with selling IMO such inferior products

I agree, the price sure wasnt inferior....but im not too impressed with coralifes service. Also the time its taking to figure out the problem, i waited 2weeks for this new ballast, and it didnt fix anything.

How did you or Coralife confirm the Ballast was defective? Just courious as I dont trust any of the components - also maybe it will give me a heads up on what to look for if I suspect a faulty ballast.

I've also noticed that my Coralife 10000K pc bulb looks more yellow than my other one by Hamilton - both very close to the same age - and the Hamilton was cheaper!

i've only had my coralife 10,000K 150watt for a month now, and seems to be giving a strong yellow tint. could this be the reason for my recent boom in green algae growth?

it has been suggested that there is a breakin period for full brightness and spec'd spectrum, however i haven't had to replace my coralife 150w 10k pendent DE style yet, still has a half a year left yet. no problems at all though.

I find it funny that during or after the break-in period the buld has shifted to a yellow tint and is not as bright as a new one. Then again maybe there are a 'few' Coralife bulbs in existence that do work properly.

I think I might change mine to Geisemann 13K - I have heard nothing but good comments on these bulbs.

That was a guess by the store I bought it from.
