AllPondSolutions لمبة UV PLL 36 واط / لمبة 4 سنون - بركة/حوض سمك

Swapped this 4 pin bulb into my steriliser and the water cleared up within a couple of days. Handy that the one lamp fits so many different units, so I'm not hunting around for a specific spare next time.

Kept a spare of this 36w PLL bulb in the shed and it's already paid off—swapped it into the steriliser in under a minute when the old one went out. Fits the popular brands without any fuss, exactly what the listing said.

Fits perfectly into my existing steriliser unit, and it’s nice having a backup bulb ready to go. I only wish the packaging were a bit sturdier, but the bulb itself works fine.
