This is a 27W circular fluorescent light bulb! I bought it to replace the ceiling light, but the problem was with the fixture itself, not the bulb, so I ended up not using this one. I've lowered the price, so it's a great deal for anyone who needs it! ^ ^ "Long Life, Natural Brightness" ✅ Daylight color ✅ Long life: 12,000 hours ✅ High-frequency lighting fluorescent lamp ✅ Slim, tube diameter 16mm ● Circular fluorescent lamp FHC27 type, 38W at high output Price at purchase: ¥1,980 + tax ¥2,178 ※ Please be sure to use it with an FHC-dedicated fixture.
