New Current CF bulbs

[An t-iasg]

I just got two Current USA CF bulbs. They are 18 watt, twin-tube, SunPaq Dual Daylight 6700°K/10000°K. They rattled when I took them out of the box - kind of like an incandescent bulb that is burned out and you shake it and hear the rattle. I could definitely hear that something was moving around in the bulbs - both of them. They turned on OK and both tubes lit. Has anyone else had this experience?

Yep ,mine do it too , I just thought it was the mercury in it ... all of mine seem to burn fine as well .... I wouldnt worry about it

Thank you - that is good to know. I just didn't want them to go boom or something! 8-O

Coralifes do that too. Just changed out my bulbs last week, and was reminded of the rattle. Don't think it's mercury, but I do think it's a little chunk of whatever they use to make the correct spectrum.

Thanks, Kurt! I do have a Coralife fixture that I haven't used for awhile. But if I do get a new bulb for it I'll remember that it rattles too. It's kind of funny that I don't remember either brand of bulb rattling when the fixture was new and I put the first bulb in, but these replacement bulbs rattled loud and clear!
