- Will it fit my existing circline fixture?
- It fits 4-pin circline sockets, the round fixtures in desk, magnifier and ring lights. Check your old tube has four pins; 2-pin fixtures need a different bulb.
- How do I change the color temperature?
- There is a switch on the bulb itself. Set it before you close up the fixture, since reaching it afterward is awkward.
- Can I use it on a dimmer?
- No. It is not designed for standard dimmer switches, so use it on a plain on/off circuit.
- Does it work in 240V fixtures?
- No. It is rated for 120V, which suits US and Canadian household wiring.
- Is it brighter than the fluorescent tube it replaces?
- It matches the 22-watt output class of the tube it replaces, and owners typically find the light cleaner and steadier.
- What is in the box?
- One 22-watt LED circline tube. No adapter or extra parts are included.
