I bought these bulbs to replace halogens, and they are superb:
1. I'm using them with a conventional dimmer switch. They don't dim right down, but they do dim nicely. With some of the configurations I get a buzz from the switch, this can be solved by replacing one of the bulbs with a halogen to increase the load (or just live with the buzzing!)
2. I bought about 70 of the Cree LED 9W bulbs, and I'm now replacing them with these as they are brighter and don't produce the same focused spot so are more suitable for lighting a room. The light has a great even spread. I just wish I hadn't wasted my money on the Cree bulbs.
3. They produce at least as much light as a standard 50W halogens, which isn't true for many of the bulbs on offer.
4. I've tried the cool white and the warm white, and the dimmable and non-dimmable versions, and they all perform superbly. The warm white has a slightly yellow tone to it. The cool white is a nice bright tone, not blueish at all.
5. So far I've installed about 30 of these over the last two months and not one has failed. Can't comment on longevity yet, however.
6. The bulb is the same size as a standard halogen, so fits into whatever fitting you already have. The glass is very slightly recessed from the rim.
7. When they're off they look good in the fitting. When they're on all you see is a very even light.
Having tried a number of different LED bulbs I would wholeheartedly recommend these to anyone.
Note: I've just realised why these don't dim to super dim levels, and that's that even the trailing edge dimmer switches designed for LEDs tend to have a 10W minimum load (I'm using the varilight module). Therefore, if you put 10 of these bulbs on your circuit they will still only dim to 20%. On one circuit I have just three bulbs, so they only dim slightly. The way around this would be to increase the load on the circuit, e.g. by adding a 50W halogen bulb, but that defeats the purpose of the low energy bulbs!!
