LED lighting/bulbs

7 years ago

Is it always "better" to switch to LED bulb? I have perfectly working recessed lights (3) in small kitchen but am considering switching them to LEDs. I also have 2 in my bathroom that need to be changed (1 has burned out). Both sets are on dimmers. Is there a rule of thumb for Kelvins per square foot of space for ambient light? My kitchen has 1 window (faces East) and undercabinet lights. My small bathroom has a tiny window (frosted glass) and a vanity light.

    Yes, just bare in mind the color temp. anything around 27k will be warm, as the number goes up the more cool/blue it will become.

    Hey gargigg,


    LED bulbs are certainly becoming more popular for residential uses but, better would be a matter of personal preference really. While LEDs are generally more efficient, produce less heat, and have longer life spans than traditional incandescent styles, the technology is typically sold at higher price points. Of course, the savings benefits on electric bills and the long life spans does indeed make LEDs worth the investment.


    RL hit the nail on the head with color temperature; if you wanted the LEDs to match the warm white light of your existing bulbs, the best choice would be 2700K. This color temperature is the most preferred for indoor and outdoor residential applications.

    You should break even on the cost of LED lighting after the first year. What other investment could you make that would pay you back so quickly?


    Beware, your dimmers will likely not work with the LED bulbs. You will either need to keep them in the un-dimmed position, or replace them with electronic dimmers engineered to work with LEDs.

    LED light bulbs have incandescent equivalents. For example, a 10 watt LED is equivalent (i.e., has the same light output) as a 60 watt incandescent bulb. If you're happy with the brightness of, say, a 40 watt incandescent, just buy it's LED equivalent.

    LED bulbs are available with various color temperatures measured in Kelvin. LEDs with color temperature of 2700K have a warm glow similar to that of an incandescent. LEDs with higher color temperature (e.g., 3000K, 3500K,...5000K) will appear increasingly whiter, then bluish.

    Your old dimmer may not support LEDs so you may have to switch it for one that does. This Eaton SAL06P2 dimmer worked well for me but not all LED bulbs are compatible with all dimmers.

    Thank you all. Both sets of lights are on dimmers, so if it's true that the LED bulbs are not dimmable, then I may re-think it. I do like that feature in both rooms.

    For new projects we only use LED. My personal home was completely remodeled in 2012 and was entirely halogen bulbs. In the 8 years we lived there we replaced one light bulb and it died the week we moved in. Never saw a need to replace them.


    The apartment we are moving into (house has sold) has dim fluorescent bulbs in the recessed cans, they are being replaced with 3000k LEDs tonight

    HALLETT & Co, do you have dimmers on those recessed cans?

    Every light in my house other than the closets has a dimmer

    There are dimmers for LEDs and IMO LEDs are a good investment and I happen to like 3500-5000K range to keep colors looking true in the evening most of my clients opt for 4000K and IMo no one wants that yucky old yellow light that came from incandecsent lighting which BTW where I live has not been available for quite a long time already.
