I just bought a set of 4 UV bulbs for a nail dryer machine. However, each bulb shares the same socket mount as a CFL desk lamp I own. It works with it's standard 13W florescent bulb. Each UV bulb is a 9W bulb, and fits in the desk lamp perfectly. However, when I turn the lamp on (w/ the UV bulb installed), it appears that the bulbs (all four) don't work. No clicking of the bulb heating up, no light, no sensory indication of successful operation. Now I know UV bulbs don't put out much light, but even in a perfectly dark room the bulb produces no light. What's going on? Do I have a bad batch of bulbs or is my lamp not appropriate for the task?

Also, do these bulbs take more than a minute to heat up? I've only left mine on for no more than 10 seconds.
