So, the first 4-pin triple tube fluorescent bulb goes out. I’ve changed a lot of screw-in incandescent and CFL bulbs, but never a 4-pin bulb before. While high ceilings and recessed lights can result in an uncluttered look, this combination also requires the beckoning of a ladder instead of a standard folding chair to swap light bulbs.
With aforementioned ladder in hand, I climb up to inspect the light fixture. A quick glance shows that the baffle must be removed first. With no obvious ways to remove the baffle, I pull and pray. Fortunately, I guessed right. As it turns out, the baffle is held in place by two metal clips that provide tension against the recessed lighting fixture to hold it in place. Whew! I quickly remove the bulb and search for a replacement.
The defective bulb was a USHIO UFL-CF26TE/835 4-pin triple tube fluorescent bulb. I stopped by Lowe’s and buy a lot of Sylvania 4-pin double tube fluorescent bulbs. The next day, I returned all the Sylvania bulbs because the bulb would not snap in place. 4 pin is 4 pin right? Theoretically, all that should matter is the base and whether I’m using a double tube or a triple tube fluorescent bulb should not matter. Regardless, something was amiss. I’ve never experienced such a problem with a screw-in bulb before, incandescent or otherwise. So, I stopped by a lighting store and picked up a General Electric Biax T/E Eco 26W 4 pin compact fluorescent lamp. Thankfully, that one fit.
Light Bulbs Etc. has a chart with the different halogen, incandescent, and CFL light bulb base types. I just learned that there is more than one type of 4-pin base for CFLs. Who would have guessed? A later trip to OSH showed a surprising selection of pin type FEIT CFLs to choose from. Next time, I’m going there. They had more 4 pin CFLs in stock than the much larger Lowe’s. That surprised me.
