I purchased a CoralLife double strip 2-65 watt 24" Power Compact Flourescent light strip from Hellolights.com
it came with actinic blue and a 10,000 k light bulbs
now my question is, i noticed some sounds from the light bulbs..when i tilt the bulbs left and right in a waviny motion, i hear little tiny movement inside, as if something is loose...
BOTH bulbs have that sound, and in each tube (each bulb has 2 tubes, for those of u that know what a PC fluorescent looks like)
if you tilt it down and peer into the tube, i see like a little black thing, like a tiny sand grain or rock in each tube that rolls around in there. each tiny black sand grain looks exactly the same.
Now my question is, do all PC bulbs have a little black rock thing inside normally? This is my first PC light bulbs...
in addition, i've never had actinic blue light bulbs before, but it looks ALOT duller and less luminous than the 10,000 k... how can you tell if the bulbs have been used?
