Do the LED lights come up to full brighness when you turn them on?
I don't like the flicker. I have some fluorescents in my shop.
I can go upstairs and make a sandwich before they brighten up.
That suggests to me that I'll leave them on. That suggests to me that I'll spend
more on power than if I had incandescents for 5 minutes to see what I'm cutting on the bandsaw.
Same in other rooms. I want BIG light, right now, for 2 minutes then off and I'm out of there.

I know its not exactly what you meant, but I use a rechargeable LED headlamp from REI all the time, in the shop & out. It has spot, flood, high, low, flash.... and for night, red on or red flash. I've made some jiggie things to hold it when I want to use it as a worklight but not on my head.

led lights come on bright right away.
led's are still to over priced for shop lighting but the price is coming down fast.
i have swapped all my out door lighting to led mostly because it is on for 6 hours a day.
i have 2- $39 led flood lights in a $7 fixture, ouch.
but the payback will be short because of the amount of time they are on each day

most t8 and t5 fluorescent lights have quick start any more.
if your using the screw in bulbs or old t12 fixtures,
i'd recommend swapping them out for some t8 fixtures.

I recently changes the lamps in the shop fluorescent fixtures to a higher color temperature. It's measures in Kelvin degrees (K). The old lamps were around 4500K. The new ones are 6500K and it made a huge difference both in lumen output and color temperature.

6500K is closer to natural sunlight in color temperature. When I used to keep a reef tank, I used 6500K metal halide lamps to mimic natural sunlight. The corals and plants seemed to love it.

LED light come on to full brightness when they are turn on. I have three small flood LED over a kitchen counter
and the continue to glow for a few seconds when power it turned off.

I recently installed LED under-counter lights in my kitchen as well. It made an amazing difference. I only spent $150 on a kit with 10 LED strips but they are not the most durable LED fixtures I've ever seen.

Here is a picture of the kitchen with the lights on. You can see a couple of the wires because I had not hidden them yet. http://inconcepts.biz/~jsw/img/11211...n_lighting.jpg

On the other hand, I do not have LED lighting in my garage or any other areas of my house. I have CFLs in most of my lamps and 48" fluorescent tubes in the garage.

I feel LEDs are generally too expensive to benefit me right now. Once they become cheaper I will probably buy them for other rooms.

I have electric heat (no gas, etc. here) so if I save 1kWh on lights by changing from incandescent or CFL to LED, I will just spend 1kWh more on the heat -- during the winter.

In summer it would reduce my air conditioning load. However I do not think the savings on lights would pay for the LED bulbs yet. Really the best way for me to save energy during summer is open the windows and use the AC less, and that is what I do until it gets pretty hot outside!

Another advantage of LEDs is that they can be dimmed a bit. Usually a low/med/high (not infinite, like IC or halogen). Much cooler, low profile, instant-on, low voltage, low consumption. And since they don't need fixtures, if you were planning on buying fixtures and bulbs for recessed or tube fluorescent, it's not much more to go with LED strips, which will end up being saved in electrical costs and lack of bulb replacement. Bonus, they are whole lot easier to wire.
