This 5W UV-C bulb is a replacement part for aquarists who run a SunSun CUV-505 sterilizer and need to renew the UV source. It is rated for 8000 hours of operation and fits the SunSun CUV 505 model according to the supplier's compatibility list.
Why it matters
- Rated 8000 h lifespan: the bulb is specified to run for 8000 hours before replacement.
- 5 W output: the bulb is a 5 W unit, which defines the UV-C output of the sterilizer it is installed in.
- G3.5 base: the bulb uses a G3.5 connector, so the base type is clear before ordering.
- Known overall length: the total length including pins is 15.7 cm, which allows a direct size check against the existing lamp.

What it works with
The bulb is designed for the SunSun CUV-505 UV-C sterilizer used in aquarium water filtration. The sale covers the bulb only; the black lamp housing shown in the photos is not included, so the existing housing must be retained. Before purchase, compare the 15.7 cm length and G3.5 base with the bulb currently installed.
