Yes - rid yourself of the ridiculous idea that you can light a room with an array of 2" diameter torches, and install something actually designed to do what you need.
megaman. search ebay. i got 6 from there for about £20 (usually about £6-8 each). im not suggesting you bulk order straight away though - you might not like them!
No, because you are starting from a position of utterly non-sensible lights in the first place.

As i said, its a rented house, so i cant really go hacking the roof around to change the lighting, and to be honest, it lights up the kitchen pretty well as is.
Yes, though I have noticed a marked improvement with the newer models. Though it could just be because I'm comparing with lamps that are about 3 years old (get sluggish with age)
Those exergi bulbs - whats the need for all those ribs and vents on them? If they really do give off virtually no heat, why add cost by over-designing them?
They don't give off much heat when compared to incandescent lights, but bright LEDs do produce a great deal as a percentage of their overall consumption (85-90%), and there is actually a serious problem with keeping them cool, because they cannot tolerate the amount of heat they produce.
It's a dead-end technology, basically, and will be dropped by the makers as soon as something else (e.g. OLED, ESL) is available.
it does seem to me that LED is going to end up no more efficient than CFL. When you consider they claim a 7 watt LED lamp is equivalent to a 40 watt halogen. This isnt much better than halogen, and is probably over-claimed.
People were getting excited by LEDs a few years ago when the first lamps had a cluster of about 21 LEDs for about 2 watts. Oh great. But they were useless. Now we are getting close to CFL / halogen output, they are becoming equivalent to CFLs.
