Got a brand/supplier for the LEDs?

The brand is Peritus. The supplier was the usual "some guy on eBay"
which I suspect is a front for Peritus, charging less than their prices
on Amazon.

I had a bit of trouble finding them again since they didn't leave
feedback after I bought the bulbs. They have an eBay shop:

They charged about £6.50/bulb if bought individually and £60(ish) for
ten or more with free postage. I bought a mix of MR16 and E14 R50 from
them a year ago, so far I'm pleased with the bulbs.

The ones I chose were the 21xSMD units which put the SMD elements
directly behind the front glass of the bulb. This gives even
illumination over a wide area. They also have units with a number of 1W
packages in each bulb which I avoided because it seemed to me that these
would produce spot lighting.

These seem to have fallen in price and are now about £5.30 per bulb
bought in bulk.

And the MR16 has fallen to about £1.90/bulb which seems good VFM to me
compared to the price that Ikea charge for CFLs that don't illuminate
worth a damn.

I haven't changed the transformers used for the halogen lighting tracks
(yet). If I use all LED bulbs there's unacceptable flickering - the
bulbs don't draw enough current for the transformers to provide stable
output. A mix of three LED to 2 halogen bulbs keeps things stable. It's
noticeable that the 35W halogens have lower light output than the 3.5W
LEDs.
