"I thought that a larger transformer would better regulate against line spikes and voltage fluctuations" Maybe, but not always. Keep in mind that low voltage often requires higher current (though LEDs are not as bad as incandescent bubs). Wiring that runs concealed inside walls get smacked by the whole electric code unless the voltage and current are both low (power limited circuits) Wiring on the underside of cabinets at low voltage gets a lot of breaks. Even more if the circuit is also low power (power limited circuits, think like your doorbell or thermostat). Even with LEDs you may not get all tat much light from theses low power circuits though. LEDs sound great at only 10 mA each, until you need a lot of them for bright task lighting, let alone if you want a 3-color setup for varying light color.

If you're looking for LED recessed lighting, it is extremely difficult to beat Cree. The only other brand that is worth considering is the Sylvania RT6. Having a single transformer in one location works for under cabinet lighting since the total length of low voltage wiring is small (typically For recessed lighting, the total wiring length will be much longer since the lights will most likely not be daisy chained in series. The total wattage requirements will most likely exceed 100W, requiring a larger transformer and thicker wiring. There are tables available for low voltage wiring lengths and thickness. The voltage drop across the longest run may also be too great for the light to work properly. In addition, the transformer would need to be in an accessible location to be changed out. The housing itself will

It should be easy. We have the transformer in an upper cabinet. Look at www.inspiredled.com

Depends on how you want to control them. If all you are doing is turn them on and off, it shouldn't be much of a problem. If you want to dim them, that's where issues start to crop up. Not to be too reductionist or too simplistic here, but most LEDs are solid state electronics, not really technically electrical, and require low voltage DC power, so not only is there a transformer (whether you see it or not), but usually some sort of AC/DC rectifier. Not all electronics behave well to being dimmed with typical rheostat wall switch dimmers. That's also why some LED lights have a slight delay turning on, the electronics. Even if they say they handle 120v and can be dimmed, it doesn't always work as advertised. Depending on why people on these forums recommend the Inspire LEDs (I'm not familiar with them) I would still stick with something either I know or people I respect know. If I want to dim LEDs today, I would buy a whole system that includes the lighting controller—like a Philips HUE system for traditional style light bulbs. LEDs have not been perfected to the point that anything you buy will behave properly. But if none of that matters, just get whatever you want that behaves like you want it (if you don't want the delay in turing on, for instance) Joe
