truly instant on? cree lr6 and lr4?

Is it truly an "instant on" when you flip the switch on your CREE LR6s or LR4s? No delay as with CFLs?

I mean, even first thing in the morning, after having been off all night?

I'm starting to work out more of the nitty gritty details of our kitchen remodel, and am investigating whether the CREE LED recessed lights would make sense for us. While *not* CA, we are energy conscious. We saw the LR6 and LR4 on display and think either might work for us. (Our kitchen right now is stuck in the 1950's, so anything more than the current three 60 watt incandescents would be a brightness improvement!).

One thing that annoys me about CFL bulbs is the delay to come on after you flip the switch. That's why we still have the 3 incandescents in the kitchen--tried the CFLs but the delay was really annoying. If the LEDs are going to be just as annoying, then that'll be something to ponder.

Thanks in advance for any anecdotal opinions!

yes. No delay at all.


Truly instant on LED lighting cree lr6 and lr4?

LED lighting is instantaneous, dimmable and has great design flexibility. I now use under cabinet lighting more frequently than LR6.

RE: truly instant on? cree lr6 and lr4?

All of the above is true, and LED bulbs are expensive up front. In the long run perhaps they are not so expensive. For instance look at this LED can bulb. It's $70 up front, but only uses 6 Watts and they last a lot longer than incandescent so depending on the application and user it may be worth it.

Hi David, thanks for weighing in!

There's something about the initial light when entering the room--to see where I'm walking--that makes me so hate a delay. I don't mind the delay in places where I'm already in the room with some ambient light, and then want to flick on a particular location for some task. I have another question about the undercabinet lights, though I think I'll start a new thread on that one.

Hi housavvy, thanks for your input.
I really appreciate your point about the up front expense. The person at the lighting place we visited said that going LED was like buying your electricity "up front". That you are spending more earlier, and there will be a payback time at which you reach the equivalent. For home kitchens, he suggested that if we're going to be in the house less than 5 years, to do the lower-priced CREEs (the CR6s, if they come out in time) or not LEDs--because the payback for the lower-priced LEDs would be about 3 years, and then it gets longer the higher in price you get.

Balancing all of those things (time before payback, quality of the light, delay in coming on, etc) is key. I do know that having a delay upon entering the room is a showstopper for me personally, so hearing how things are actually behaving in real life is terrific. :-)

Before you start another thread on undercabinet lights, there are already a number in existence, eg
