new LED technology?

[gatchel]

That Cree LR6 is pricey, ~$90/bulb, sans housing.

I wonder how long it will pay for itself.

Of course, if I factor in the headaches of changes the scores of can light bulbs in my house, they may pay for themselves a lot sooner. Especially the ones that are 25' up.

I'm guessing they'll come out with a 4" retrofit bulb soon, as well as outdoor floods.

The biggest prob with these LED's, of course, is the color 'temperature' - sounds like Cree is there now, though I'll have to see for myself. Thanks for sharing your experience, Mark.

I have 5 (soon to be 6) Cree LR6 lights in my kitchen. I paid $90 each at the local supply house. I LOVE them. I compared them to "reveal" lamp, a standard lamp and to CFL's of varying brands.

They look the best , hands down. I calculated my $0 point at about 5 to 6 years with the amount of time we use them every day, after that all costs are covered and the rest is savings.

The LR24 is ridiculously priced right now. It won't retrofit into a 4" can either, only a 5" can. I remember it being double the cost or more. You have to buy the light engine, the reflector (lens) and a GU24 socket adapter for a complete retrofit.


You also have to remember that I did this installation during a renovation so my actual cost was slightly less than $90 per bulb. At $5 per light bulb and $20 per trim ring I figure the real world cost was $65 for a new install of these units.

There is NO color temperature issues with the LR6. They look better than incandescent, IMHO.

was just @ costco and ran across 5W LED flood lights - 45W equivalent - for about $14 each.

Put them in And I'll bet they look horrible. I have tested every LED and CFL from just abouut every local store. Home depot, Lowes, Wal Mart, Target, Sams Club.

You get what you pay for.

Also, who uses a 45watt bulb in a fixture these days. My guess is that they are estimated at a 45watt equivalent but you lucky to get the real world performance of a 30 watt bulb.

I figured I be a PH here today.

I took apart the LR6 for those who are interested:

Thanks damage - was there today and picked one up for my front porch flood. Will see if it's bright enough tonight.

For those who haven't seen LED accent lighting, here is night shot (with snow) of the first two walls. Each light is 1.2 watts of warm white light. These are high quality LEDs (made in Canada), which are suppose to last longer, and are considerably brighter than the cheaper variety. Each light fixture is approx $50, the transformer is about $140 and can handle up to 30 of these fixtures.
It wasn't easy to get a decent night shot with my digital camera, and this pic really doesn't do it justice. If you look closely you can see where the light hits the ground providing plenty of light for visitors and for security require very little power.

I switched all the CAN lights in my house over to Cree. They are fantastic. I don't use the dimming much but they dim very nicely, down to maybe 25%.

What dimmer do you have them on?

Very nice. Can you give some more information on the specifics of the units. Have a link to the manufacture or even better a supplier?

Thanks,

Thanks,

They have quite a few other units too, These particular fixtures come in a mounted bracket version and a pot light verson. I used the unit with a bracket as my evestrough is wood and they sit nicely up underneath and the bracket give you plenty of flexibility of movement.

I use UPB dimmers, but I think any work. Have tried a whole lot of other LED bulbs and they never dim, these do.

I tried a string of 3 LR6 modules on an insteon Keypadlinc dimmer. It was a little bit noisy and flickered ever so slightly, too much for my liking.
Cree has an approved dimmer list if you are purchasing new. I don't think the list includes any HA dimmers.

Hmm, I might have to try these out. Finishing off my garage and cfl's are just not an option, it often gets down into the -20 degree range at night and it takes forever for cfl's to get to any kind of useful brightness.

Does is look more like this?

Are you using the 2700K warm or the 3500K neutral or a cooler temp? We use 6" PAR38 65W and 75W floods in the kitchen and bathroom. Tried CFL floods and hated them. Took forever to warm up. Color was too yellow when cold, and too "fluorescent looking" when hot (after 2 minutes). I don't want an LED that is too low on lumen output, or has too narrow of a beam. $90 is a lot, but I would be willing to try a pair of them over the kitchen island or bathroom counter if they worked well.

These are at least as bright as the 75W bulbs they replace. No warm up needed. 2700K are the ones that duplicate what you get from an incandescent bulb, so that is the one you want unless you have a real good reason for the 3500K.
