LED downlighters

We've been fitting them in the bathroom as the halogen fittings fail. I remembered them as being ~40 (I suppose 30 + VAT = 36 and there's delivery on top, so close). They have worked well for us.

Ebay is a good source.

Assuming normal bathroom use, will you ever get your money back?

Look like a good quality unit with real numbers, including the CRI of

Look a nice unit but do you really want to dim them? Swapped out the 10 50watt lamps in my kitchen for 3watt warm white sealed

Looking at a row of 3 above the kitchen work surfaces.

Yes, I do want to be able to dim them so I can have low mood lighting spilling out into the rest of the kitchen/dining/living area. Can't be sure that I'll want to before the whole room comes together, but better to allow for this than be irritated by an overly light or dark kitchen area.

Do all three colour options have the same problem? That is daylight white, warm white and neutral white.

There will be a central pendant light in the kitchen area - these are additional ceiling level lights over a run of work surface (no wall mounted units) to give direct light onto the work surface to avoid shadows.

The light qualities of LED is ideal for mood lighting. Assuming you want to be in a bad mood.

LEDs themselves are always dimmable, but the psu used with them isn't always. If you're wlling to open it and know what youre doing, dimming can be achieved, and will prolong LED life.

Afraid so, warm white has a boost of yellow at the expense of efficiency, generally lose about 20% getting light quality like a 1989 CFL...

Good fluro can reach a CRI of 90+, some LED with mixed amber LEDs is getting to 85+

Halogen has a CRI of 100....

Bearing in mind LED units you`ve linked to are 10W at 42l/w at 30 quid each need to be running for most of the 24 hours in a day to make any saving over updating halogen.

Replacing GU10 with 12V 20W halogen, which with improved beam control will be at least as bright as exsiting 50W units, be cheaper to install and give a more satisfactory dimmable light in a living area, decent MR16 halogen`s are 25l/W nowadays and lamp life in the 2000hr+ range.
