    Looks great in tank of an evening, seems soothing for fish, calm swimmers at night. Helps keep the daylight brightness at a good level too…use to start the day and end the light cycle.

    Much better than the old halogen bulbs that get too hot. These still do get hot but no where near as bad as the older bulbs. A nice bright white colour for the white oje and the blue is nice too.

    Excellent replacement for the mini flourescant type bulbs that we normally used – although the power saving isn’t that large between these and the CFL type bulbs 7w compared to between 11W and 15W the reason for shifting to LED was for longevity – the CFL type bulbs tend to fail after about 6 months to a year – we were spending money each time to replace – these LED have already lasted longer (hence time taken to write review)Very happy with these – bought both the daylight white and moonlight blue lamps – they are brighter and really show off the vivid colours of the fish much more than the traditional bulbs. Direct replacement like for like.

    These were reordered having received same in the past. They arrived well packaged and seem to last between 2 and 3 years as landing lights on most of evening particularly in the winter months. Very pleased with the product. Thank you

    I was under the impression that LED lamps lasted a long time, my last one only lasted a few months

    Browsing through my order history I noticed that I purchased this almost exactly one year ago. The bulb has been faultless throughout that time and is still going strong despite have a good few hours under its belt. It was purchased to replace a moonlight CFL that had burnt out.Being LED, this runs brighter yet cooler than the old bulb and consumes less energy. There is a large heatsink on the back of the bulb to help keep things cool. The bulb only has LEDs on one side (essentially a panel) and once installed can be rotated to the correct orientation for your tank. It is significantly smaller than the old bulb but the light spread doesn’t seem to be affected. The colour of the light is a cool blue, bordering on violet. It is quite noticeable the difference in appearance at night between this and the old bulb – things seem to pop from a near ultra violet effect. I still run a daylight CFL but wouldn’t hesitate to swap for the LED when it finally goes (I’m not a fan of replacing bulbs for the sake of it).I have seen cheaper LED bulbs around but like the reassurance of a brand name as this is something that will be left on for hours at a time and I like to minimise the risk of fires. I’m not knocking cheap bulbs but hope that brand names have gone through proper testing and quality control.====Update: bulb purchased Jan 2017 and still going strong in Mar 2020

    Quality item for the aquarium. Lights up the tank beautifully and uses half the power of the original light. What is there not to like
