LED's are an expensive initial outlay but do save you quite a bit of $$ over time. Plus, it's 'the wave of the future' and eventually all you're going to be able to buy so may as well power up for that in your shed now. And yes, they, too, come in various color ranges.
I will say this about the dimmable ones... Not sure if it's because we are using them in an older fixture or not. Not only do you need dimmable-specific LED bulbs, you need to marry them with the same brand/manufacturer dimmer switch. AND they do not come on instantaneously like an incandescent bulb - there is a several second delay. Frankly makes me crazy when I walk into the office first thing in the AM to cruise here with my coffee!
