Hi all,

We have one of those 3 lamp ceiling spotlights that currently has 3 x
50W halogen lamps in it that I would like to change to LED and one of
the dimmer switches that was previously recommended in another thread.

However, I've never used / had a GU10 fitting or even changed a lamp
(thst I remember) and certainly don't therefore have any feel for just
how bright they may be (ITRW) in comparison with the supposed
watt-equavalent halogen.

I recently did this. Dimmable bought from TLC. Not as bright as 50w
halogen, closer to the smaller ones - 35w? Light quality not quite as good
either (warm white). But overall, reasonably happy.

They also seem to range in price considerably and I'm not sure how
likely that would reflect quality / reliability etc?

So, could anyone personally recommend a 'good' (VFM / reliability /
light level and dimmable) LED GU10 lamp please?

I think we would want 'warm white' (it's in a bedroom) but ideally at
least as much light as seen from a (well 3x) 50W halogen lamp please
(if that's possible etc).

Sadly no low energy lamps ever seem to match the output of the larger
tungsten types, despite the claims.

As mentioned elsewhere in this thread, the effective angle of
illumination is often much less with a led, too. Also, despite TH lamps
having a very bright filament, it seems to me that leds can "outglare"
them with their often very bright pinpoints of light. However, I
recently bought some GU10 leds which had the front glass frosted. These
provide a much nicer light without glare.

Thanks for the replies guys, this is the sort of 'real world' feedback
I was hoping for.

I'm wondering now if the starting point was a good one, eg this 3 way
fitting with GU10 lamps? [1] Ok, the user (a young 'goth' g) liked
it being provided for her (along with the black walls, all part of the
surprise) but none of that makes good lighting 'easy', and hence why I
was aware of not wanting to make the room any darker whilst trying to
offer more control of the light level whilst saving them energy.

Maybe I'll run the idea of changing the fitting to something more
suited to the more powerful LED lamps available easier in the bigger
bases (BS / ES) but retaining the idea of providing the remoteable
dimming function to give her something to play with.

If *I* had been party to choosing the light fitting I think I would
have considered the availability of lamps and generally at the cost of
any ideal 'style' (I'm not a form over function type of guy). ;-)

As a aside, the heat given off by the 150W of halogen wasn't such an
issue when it's cold but would be as the temperatures start to go up
.... and because it's a bit dark in there (black walls and bed sheets
etc) you do still often need the lights on in there, even when it's
fairly light outside (or sooner than you might if the walls where
white etc).

It's nearly one of those things where you find the lamp and then work
back to the fitting! ;-)
