Excellent low energy space lighting
on 11 June 2013
Update April 2015 - We have been running up to 15 of these in the kitchen, utility room and bathroom and for nearly 2 years with no failures yet! They will have seen 2000 - 4000 hours use, as some of the rooms are north facing and need a lot more lighting. Only one lamp has shown any signs of flickering and strangely that stopped about a week after it started.
These LED GU10 replacement lamps provide 120 degree cool white lighting, which we find brilliant for the kitchen, utility room and bathroom. They use about 11% of the energy of an equivalent halogen GU10 lamp and give a much broader spread of light, which is great for the rooms that we use them in. The cool white lamps can give a very 'clinical' type of lighting if you are not used to it, but we find it much better in the rooms I have mentioned. There is a 'warm white' option of this lamp available, if you prefer that type of lighting, which many people do. This tends to be more suitable for the lounge or bedroom (in our opinion anyway).
The 120 degree light beam from these lamps is great for providing shadow free lighting in areas where you need all-round lighting rather than spot lighting (traditional GU10 halogens tend to give a 38 degree beam). These lamps do look a bit strange when you first fit them, with the 27 bright yellow LED cells, but you soon stop noticing that, well, we did anyway.
Whilst the initial purchase price is high, the rated longevity of the lamps coupled with the low energy usage, makes them a sound buy from a cost and energy reduction point of view. I have rated them at 4* because we have not been running them long enough to find out if the life cycles are as long as claimed by the manufacturers. I will update as we get more experience. I bought 12 of these to start with and all have run OK so far - they do come with a 2 year warranty so keep your proof of purchase!!
The only thing I cannot find out is how their performance varies with age - compact low energy fluorescents are well known for giving a lower light output and a much warmer or yellow light once they get to around 80% of their rated life. I would like to find out if these LED GU10 lamps suffer from the same problem, but there does not seem to be any easily available info on that. Anyone have an answer??
These lamps do seem to fit any lighting that accepts a standard GU10 lamp and the ones that I received stated that they were suitable for use with dimmer switches - I cannot comment on this as we do not use them!!
Initial experience has prompted me to buy another set of these lamps to replace the other GU10 lamps in the house, which are going to fail soon anyway!!
Update December 2013 - After ~ 8 months use we have not had one premature failure of these lamps (and some of them have already run in excess of 1100 hours in the north facing parts of the house). The reduction in my electricity bill is a very welcome benefit of running these lamps.
Update August 2014 - After 15 months the lamps are still performing well and not a single failure so far - fingers crossed!!
