10W UV lamp for the CUV‑510

This is a 10 W UV-C replacement lamp for the SunSun CUV 510 sterilizer, aimed at aquarium owners who need to restore their sterilizer after the original bulb has worn out. It uses a T5F 4-pin connector, so it can be swapped into the CUV 510 without changing the unit.

Why it matters

• The rated lifespan of 8000 hours is the main value for the owner, since it is the operating time the lamp is specified for before replacement.
• The 10 W output matches the power rating of the CUV 510, so the replacement corresponds to the sterilizer's original specification.
• The 4-pin T5F connector is the standard fitting listed for this lamp, which makes installation a direct bulb exchange.
• At 0.1 kg, the lamp is a light spare part that is easy to store and keep on hand for a planned replacement.

What it works with

The lamp is designed for the SunSun CUV 510 UV-C sterilizer, which belongs to the aquarium filtration and UV-C sterilizer category. It is intended for freshwater and marine setups that already use this sterilizer as part of their filtration. Check the sterilizer model before ordering, as the lamp is listed as compatible with the CUV 510 only.
