Short life with AH supply bulbs??

I ordered a 55w 6700 power compact bulb for a coralife 24" 65w single strip with no fans. That was in May. The bulb fryed a couple of days ago. The AH supply bulbs are thinner in diameter than coralife (maybe the 10w difference?)
Luckily I picked up a light this week from a member and had a extra coralife bulb to use for now. I do not know if its the fact that there are no fans or not, The fixture gets pretty warm . The JBJ with fans is cool to the touch. I am thinking about ditching the clear panel under the light since I have legs and a glass top to let the air in and heat out. Any one else have a fan-less coralife and have problems with bulb life??

Never had a problem with AH Supply bulbs. But then again I'm running them at their rated capacity of 55 watts and not 65 watts.

Rex's got a point. a 65watt bulb should work fine in a 55watt fixture...but a 55w bulb in a 65w fixture is being every so slightly over-driven, and we know over-driving reduces bulb life, and PC's aren't meant to be over-driven at all (to my knowledge).

That concerned me before and then I read this on Hello Lights website.
*** FAQ:
Q. Are these bulbs 55W or 65W?
A. (Note: This applies to both Compact Fluorescent and Fluorescent bulbs only.) Actual wattage to the lamp is primarily a factor of the lamp electrical characteristics and the ballast driving the lamp. Without getting too technical, the wattage marking on the lamp does not necessarily determine the actual wattage to the lamp. (i.e. you could have 100W to a lamp that is marked 55W!!) Fixtures with different ballast will have different wattage to the lamp and as such the wattage marking on the lamp is for reference only.
Actual wattage to the lamp operated by electronic ballast can only be measured using special high frequency wattage measuring equipment. Input wattage to the ballast is not a direct indication of wattage to the lamp.
Simply put, 55W and 65W lamps have same or similar electrical characteristics and therefore if one replaces either lamp into a given fixture (either a 55W or 65W system) then the wattage to the lamps will be driven by the ballast(s) of such system. Wattage to the lamp determines lumen output or total light output of the lamp.
Conclusion: Lamps marked 55W or 65W can be interchanged with similar or equivalent light output performance. The ballast drives the bulb.

I ordered 55W 6700K bulbs from AHsupply PC. If they short out or die within 12 months, i'll let you know.

I had a Coralife bulb konk out prematurely myself. I replaced it with a JBJ bulb, as this was the only bulb the LFS sells. We will see what happens.

hellolights.com has some of their bulbs custom manufactured...so they may be producing bulbs that can handle 65watts of power.

Well I know my electronic ballast (from AHSupply's 55W kit) can handle a bulb "up to 65W". Does this mean the 55W bulb I connected to it is actually running at the highest possible output of the ballast?

The only thing I am concerned about is 55w straight pins are easier and cheaper to find than 65 w in 6700k but will they last in a 65w fixture. or burn out like the last one?

I have had the same problem with a fixture that I purchased from Petsupply Liquidator. It is a 4X55W PC fixture with no fans. I had a bulb burn out in July after 6 months of use and just had another burn out maybe a week ago after 8 months of use. They are both on the same ballast, so I hope there is not a problem with that ballast. I tested the ballast by swapping with the bulbs that worked and it seemed o.k. The bulbs they sent were made by a company called Catalina. I may try other bulbs like JAlli ones to see if they would be o.k.

Met someone who wants to let go of their 4x65w Coralife Aqualight for cheap, but don't know if I should take up the deal. Anyone successfully use the GE 55w 9325k in their Aqualight without burning out too early?

Will there be a problem running 2x55w and 2x65w (kept on separate ballasts)? I assume both ballast are completely independent of each other.

I had a 55W AH supply bulb burn out in 10 months
I had it on for 15hrs/day
From what I've heard its just a defective bulb and I definately would try another if I had a 2x55 but I only have 1 socket and using the GE 9325.

Did some more forum searching and it seems ok to use the 55w bulb in the Aqualight. Came across your post too, ming; looks too me it was just defective as well.

Two quick ones:
- With legs do the lights shine into your eyes?
- Are the fans easy to replace?

Well i can tell you i have a 96 watt CF from AH supply that has been running strong for over 2 years not 12-15 hours a day and it still looks great i moved it over one of my low light tanks when i got a replacement and there is not much noticeable "visual" difference in out put to this day.
