LED recessed cans vs standard can lights?

A friend mentioned to me that if I replaced my standard recessed light cans with LED cans that my energy usage would be significantly less. But I'm confused, as I have nice Philips LED lights screwed in there now -- and I see it as energy consumption is what it is, so how does that make any sense?

Can someone explain whether that's true or is fluff?


Thank you

Like incandescent bulbs, LED bulbs create heat. The difference is that LED heat is created at the base. The heat is then pushed away from the bulb and toward the fixture. This is compounded when the fixture is over the bulb, getting even warmer as heat rises. For this reason you should be careful when using LED bulbs in a can not designed for them, particularly if the fixture has a cover.

@Tony,
LED bulbs do generate some heat, but FAR less than the heat from an equivalent incandescent.
@forrie,
If your current LED bulbs are doing fine I doubt that the same amount of illumination from an LED can will use any less energy. As far as safety is concerned you are using less wattage than the current fixtures are rated. You should be fine.

You already have LED lamps installed, changing them to LED cans will have almost no benefit. IF you are still wondering if you can do better, add up the actual wattage of each LED lamp (not the watts equivalent) and compare that to the wattage of the LED cans. You can also add in the cost of the LED cans into the mix and see how long your payback would be at your KWh rate.

It only makes sense if the dedicated LED fixtures or other energy savings are required by law. In California, Title 24 requires that light fixtures cannot accept a screw-in bulb (actually more complicated).
If you're not remodeling or getting a permit, I would keep the existing lights.

Thank you

Thanks, everyone. This is what I thought.

When I bought the unit back (I used to own it), I immediately replaced the incandescent lights with Philips LEDs (over 500.00!) -- energy use is energy use. They produce less heat, but the notion that replacing the cans would increase power efficiency didn't make a lot of sense to me!

Much appreciated
