PLEASE NOTE THE BULB YOU ARE BUYING IS A "GREEN CLEAR" PREMIUM BRANDED UV BULB. NOT A CHEAP IMITATION. Green Clear are a Premium Brand UV Bulb, Not to be Confused with many cheaper versions on the market! UV lamps used for sterilisation purposes should be replaced every 6 months ( approx 4000 hours) Lamps used for clarification of ponds can be replaced every 6-12 months ( approx 8000 hours) When changing UV lamp we recommend that Quartz Sleeve is cleaned at same time. These Replacement UV bulbs are not for aquarium use, unless fitted inside canisters filters with a UV, or fitted in an inline enclosed UV Filter. We recommend fitting these to Enclosed Fish Pond clarifiers only. (please be aware not to look at any UV bulbs with the naked eye, as it will cause harm)

Replacement for Hozelock EasyClear 6000 pond pump light, but check them on receipt
These are necessary to get clear water, they work very well, it's a shame that you can't get more than about 6 months out of a bulb. To check, go outside after sunset, you should be able to see a ring of blue light leaking out of the pump. If you can't see it then the bulb has blown so in any case you'll find out in a few weeks when the water goes completely green.Please note there is no way you can see the bulb illuminate in daylight, so don't assemble the pump with the housing off and try and stare at the bulb to see if it is working, you'll damage your eyesight. To check the bulb is working, connect a continuity meter across the terminals. I recommend you do this when you receive the bulbs in case either of them is defective from the start.

Crystal clear pond water.
This is a product that I have been using for a number of years, it is submerged at the bottom of the pond, so you have no idea if it is working or how often it needs replacing, what I can say is, that since I stared using Genuine Green Clear UV lamps six years ago, my pond water is clearer than ever it was before.

!st bulb failed after 8 weeks
Bulb fitted 1/04/19 and seemed to work well thru Amy with clear water in pond. Pond became cloudy and green while I was on vacation in early June, just checked the bulb and it it burn out. Original was still working after 14 months with little or no discolouration of tube near electrodes, this one is black thru most of one arm and not glowing at all. Second bulb fitted, let's see how long this one lasts before we decide is this is a one off early failure or endemic for this suppliers bulbs.

These arrived looking "used"
Bulbs received looked used and repackaged, but could have been burned in ( evident oxidization on element), 1st bulb failed within 3 weeks of fitting. Re ordered from different supplier !

The fight against algae
They are what they are, I can't comment on how long they will last as it's the first time I have bought these particular ones. They are cheap and appear of good quality that help to keep your water clear, which is why I bought them.

Useless
I bought these for the UV filter in my ornamental pond. I installed the first & was disappointed so tried the second. Still no signs of the pond clearing so I bought & fitted a more well known brand. The pond cleared in less than a week. I waited too long before giving up on them so missed the return deadline. Don't waste your money.
