I replaced my old UV bulb with this one and it fits perfectly. The filter now runs smoothly and the water looks clearer. I’ve been using it for two seasons and it still performs well. Easy to install and matches the original design.

Fits my AquaTeck pond filter without any issues. The light output is strong and the water clarity has improved noticeably. I replaced it in spring and it’s been working well through summer.

Great replacement for my Lotus filter. The T5 design matches exactly, and the bulb lasts longer than the previous one. I’ve used it for over a year now and it still works efficiently.
