The COB ones I have are an array of about 6x6 LEDs on the board, but you don't see the individual chips as they're embedded in the "yellow plasticy stuff".
No complaints (since I gave up trying to dim them) they tick a little as they're warming up.
I've fitted quite a few of the multi-LED downlighters now, and am very pleased with them. IMHO they are equivalent to the original 35W halogens in terms of beam spread and overall brightness, whereas the one 3-LED one I bought for the shower light a couple of years ago isn't.
Only had mine a few months, but no failures yet; not that there should be. They came with a 5-year guarantee.
I think longevity will depend greatly on where the lamps are sourced; cheapo models will have much less electronics inside etc and although will look the same at the outset, will die much sooner.
I've just done a lighting refit in my hall - 4 x 1 x 2+ metres - using 4 off MR16 3W COB LED bulbs in double downlighter holders.
The COB bulbs have a noticeably bigger light spread than single element MR16 type LED lights, and light the area excellently. The holders are machined from solid aluminium and barely get warm.
The one gripe I do have and am querying this with the supplier is that the supposed 'Warm White' is harsher than other LED lights I have.
