50W equivalent LED GU10s?
I bought some 20-25W (1.8W) LED GU10s the other day from ebay
(http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=180497438370) and I have to say I'm pleased with them. I bought the "day white" variety and the colour balance is fine for our en-suite bathroom. Unfortunately they're not really going to be bright enough to replace the 50W GU10s in another room in our house (living/dining/kitchen) but the prices jump markedly when looking at higher wattage lamps. I think I'd also probably go for the "warm white" for that room which is another reason for going for a higher wattage lamp Does anyone have any reccomendations for LED GU10 lamps with good colour balance (i.e. like tungsten), power and price combination?

The max power you can give off from a GU10 or MR16 sized lamp and keep an LED junction from melting is around 3W, possibly 5W with imaginative heat sinking. You aren't going to get close to the output of a 50W lamp. GU10/MR16 simply aren't viable form factors for high output LED lamps. Also, if you want to drop colour temperature from 5000K+ down to 2700K, you currently cut the LED efficiency in half. (Actually, it's hard to find anything below 3000K for this reason.) -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Tim Just purchased some of these for the office kitchen. (Got fed up with having my head singed (low ceiling) when making tea). http://www.ultraleds.co.uk/u1042ww-g...te-p-2248.html They perform as advertised. Less than 50W equivalent but 35W completely plausible. Pleasant white as well. I would buy again. |

I use ones like these http://www.bltdirect.com/product.php?pid=21345&cat=2510&nm=LED+Civilight+GU 10+4+Watt+Warm+White+%28High+Output+200+Lumens%29 or http://preview.tinyurl.com/3yvbxq2 They don't have as good a colour balance as halogen lamps and are expensive but last a lot longer and use less electrickery. In my kitchen I have a mix of halogen and LED bulbs. -- (\__/) M. (='.'=) Due to the amount of spam posted via googlegroups and (")_(") their inaction to the problem.
