personnaly i do not think that is an excuse, i have used mine for 2 years next week

i use 20k XM's and i highly recommened them, I know i am not the only one who has used them that long and still has had good results.... check out carl swaby's (i think i spelt ur last name wrong carl) tank tour video on, www.reefvideos.com it is the 2nd last video in the chart

he has a gorgoues tank (p.s. he is the owner of fragfactory)

HTH,
Zack

Shelley, those are the bulbs I run, they do not get puffy like that

I'd remove it before something bad happens

Yup I changed it out today. Im usually pretty good about changing my bulbs out at or even before 12 months. Ive never run a bulb to 16months before and was just kinda curious if they distort with use.

Ive got another that is right at 12 months that Im going to change out tomorrow.. curiuos to see if if bubbled out too, as its the identicle fixture.

Yeah, not normal.

Definitely not normal at all! I ran 400w and mine never had something like that happen. You may want to forward your photo onto the manufacturer, just as an FYI for them.

must have gotten too hot, do you have airflow in your hood?

Run way to hot. Do you have a fan on your light? They bubble from heat, the glass getting soft. MH runs at about 50PSI inside the bulb, so when you get it ti hot, the glass softens and it bubbles. That can be real dangerous, if the bulb explodes, shooting hot glass, sometimes up to 2200F everywhere.
