I have received three types of bulbs now
One I sought myself, and two from this thread, CRAZYs and the other linked sets.
I am not using GU10 like all you guys, for some reason all my halogen spots are MR16 type, so those are the bulbs I can review.
I will add photos after I can test side by side to show.
My inital set were cluster bulbs, they contain an absolute stack of LEDs, and as such are a little longer than most MR16 bulbs, some housings would need bracket adaption to allow correct fit, I adjusted mine with a pair of pliers in around 10 seocnds for each hosuing retaining wire bracket, simply bending the wire down slightly to stop interference.
These bulbs are rated at 4.5W, they were bought to replace 50W halogens.
I fitted my upstairs landing with 4 of them, the light is wonderful, truely equivalent to the halogens they replaced. The light produced was warm type but not as warm as the original halogens.
Second bulb was a 4*1watt type mr16, these gave just as good light as the first set i tried, fitted the housing without adaption, but has numerous problems, some bulbs DOA, and an abundance of flicker within 5 of the 10 ordered, colour was warm again, similar to the first set, but again not as warm as the original haolgens.
Third type were CRAZYs recommendation, arrived prompty from HK, these were 3*3W style. Colour was warm as with the other bulbs, and was very similar to the haolgen they were replacing. No flicker with this set, and they fitted the housings without any adaption, tighter fit than the halogens, but still well within norms. The only issue is these bulbs claim to be using more watts than the other two, as they are 3*3Watt, 9 watt, but the brightness isn't even close to the 50 watt. They seem much more equivalent to a 20watt haolgen. This has proven a big disappointment with their MR16, they simply don't give anywhere near enough light.
I'll include some pictures when I have time to post them up, and properly show all three side by side with a halogen.
One of the final set Crazys one on the right and original haolgens on left hand side down the kitchen.
