lighting/bulb question

7 years ago
I have tried to read up on lighting : watts, lumens, etc etc. But I am still not confident as I am slowly replacing the light bulbs the prior owner had installed.

I want to replace the ceiling recessed lights in the kitchen and master bath.
The attached pic are the 3 in the kitchen. These are primary lights and in a dimmer. I do have under cabinet lights on both sides too (11X7 galley kitchen). I want to change to LEDs (dimmers are compatible per my contractor). Am I looking for specific lumens ? Watts?

Same for an even smaller master bath that had 2 recessed ceiling lights (smaller cans than in kitchen) and double vanity light - both on same dimmer- + shower light/fan combo. Only a tiny frosted window in this bathroom.

Any guidelines? I want longevity, energy efficiency, but also the right “color” to keep things bright.

Light over my dining table/ LR, etc are warm lights- not day light.

    Your pic didn't post. Try again? I'm still trying to figure out LEDs. Lumens, not watts for LEDs. 5K is "Close Encounters of the Third Kind" territory as someone said here. Not a welcoming light at all but great for a workspace like a garage. People recommend 3000 K - 3500K often but I find this range yellow. All I know for sure: I prefer incandescents and when you switch to LEDs, do a whole room change otherwise you'll have pockets of warm incandescent light and then areas of 'cold' LED. There's just something "off" about LED light, imo. Also, get everything on dimmers so you can adjust as much as possible. Have you done a GW search for LED lighting? There are a few threads with actual scientific information... :)

    Sorry I'm not that helpful but I'm sure someone with better info will pipe in. Good luck!

    I have all daylight bulbs. The reason I selected daylight is because my color pallet includes a lot of reds and purples and teals. Reds turn orange and purples turn muddy brown under yellow lighting.


    My oldest sister has also selected daylight bulbs for a different reason. She is getting older and finds that she can simply see better with the brighter.whiter light.


    My other sister has a home with mostly fall colors, greens, golds, tans, oranges. She finds the white daylight bulbs too white and too bright for her taste.


    The color value is measured in Kelvins, but don't think that every daylight bulb listed as 5000K is the same. They are not. Every brand is a bit different than the next. The listed measurment of 5000 K is between 4500 and 5500 K.

    The lower the K value the more yellow the light - the higher the k value the bluer the light.


    LEDs also have different CRI values This is a measurment of how well a lightbulb renders color.

    You want a CRI Value of 90+


    Brightness of the light is measured in Lumens.

    Here is a good guide for determining how many lumens to have per room.

    I tested about 6 different lightbulbs in my home in 2 lamps and in a dimmable fixture. This was about 2 years ago. More lightbulbs have the higher CRI Values now then when I tested.

    CREE is my favorite and the best dimmable light I found. Feit comes a close second, quite economical if purchased through Costco. Both are very close in color and the difference would only be noted in a multi light fixture (wouldn't mix Cree and Feit in my bathroom vanity fixture with 5 lightbulbs next to each other). Both have good reviews, CREE has a 10 year warrantee, Feit has a 5 year warrantee. Both have CRIs over 90.


    Cree can be purchased through home depot.


    You can not also buy lightbulbs that change color 2500 k -5000 k via wifi. Not sure what the price is for these, but I am happy with picking one option.

    I like the Cooper Halo can light retrofits. The trim ring and light are integrated and easy to install. I used 3000K units, though if I were doing it again, I’d probably go with 3500-4000K. If you’re used to the yellow light of incandescents, it takes a little while to get used to the cooler light.

    GW = GardenWeb, gargigg.

    Jennifer's info about CRI value is important as well. I've never seen that info on the bulbs we bought at HD. I've seen CREE brand mentioned in a blog as well. On my list to try. Thanks for linking that helpful article, Jennifer. Never seen it before and it's what I need.

    Most of my clients like the 4000K range for LEDs IMo they best at replicating nautual sunlight with the bonus your colors read true.

    I'm a bit OCD and am passionate about art and color - collect paint color samples and help people pick colors for their homes and collect wildlife art. Lighting was really important to me. Glad I could help you out.

    Thank you Jennifer for the link. Based on that, and comments, it looks like I need 1800-3000 lumens (CRI 90ish, ~15watt equiv) and 3500W.
    Does that exist?!? I also need to find out exactly what style of recessed/can light bulb I need to buy. Seems like there are various ones.
    Can anyone tell from the kitchen pic I posted upthread or the bathroom one I posted below?
    I’ll make sure to ask my super or contractor before buying anything of course.
    Thanks everyone. Lighting is so tricky!

    What you have is a halogen MR16. Ask for an LED that fits in that fixture. It will have two pins.

    And one of the other things about LED is that it doesn‘t warm up (in color,) as you dim it. Most incandescent lamps do, and the halogen you have here absolutely does. Try dimming very low and you’ll see what I mean. I have mr16 recessed throughout my 1920s house, and I like that quality in particular. LED has limitations, still. Getting better though.


    Good luck.

    I purchased my can lighting in the CREE brand. Color is consistent with the regular Cree lightbulbs.


    Pick one brand for all the lights to avoid issues with different colors.

    Lumens are equal to Watts - CRI is not.

    When I had incondecent lighting I was likely to use 100 watt lightbulbs for most of my single light light fixtures, 40 and 60 for multiple light fixtures. I bought LEDs that matched what I would have used in the past.


    In a kitchen I would probably use the 100 watt equiv in the canned lighting.

    I used 100 watt equiv in my canned lights that are accent lights and I should have used something lower. I'll change them out when I add canned lighting to my kitchen (use the 100 watt in the kitchen and 40s or 60s in the current fixtures).


    To determine the best color for your home (K value) I would buy several light bulbs and test them in a lamp. What feels good to you and makes the colors in your home feel good to you.

    Thank you Scottiemom and Jennifer. I don't find the halogens in the bathroom as much but the kitchen lights to get hot (and in a small kitchen the heat can be felt if the oven is on too). Since I have the undercabinet lights too, I think the switch to LED in ceiling will be fine even if color isn't dimmed while brightness is.

    Do the kitchen lights also look like MR 16?

  • 7 years ago

    To figure out which Kelvins I liked best, I bought an undercabinet light from Home Depot that was adjustable to either 3000, 4000, or 5000 Kelvins. I thought based on what I'd read that I'd like the 3000K. But looking at the light on an off-white door sample, the 3000K made it look too yellow. The 5000K made it look too blue. and the 4000K looked clean.


    So I look for 4000K but find it very difficult to find. Don't think I've ever found LED bulbs at the big box stores that aren't "warm" (2700K) or "bright" (5000K). I've had to look on-line and even then 4000K is hard to find.

    Hard to say with them turned on, but I think your kitchen lights are also halogen MR16. Are those Contrast trims? Pull one of the bulbs out when you go to the store. That way they can help you find a reasonable equivalent. Some of my own MR16s have lasted upwards of ten years. I don't use overhead lighting too often, and it's almost always dimmed. They do put out some heat though, if they're on full-blast. Good luck!

    The 5000 k lights at the big box stores will range anywhere from 4500-5500. You really need to test the actual light bulbs to find out which one is the perfect color for your home.


    It suck that things are not more exact, but they are not.

  • 7 years ago

    I have Cree lightbulbs, but I had to buy a different brand for my light over the stove and it is much more blue. All my food has a distinct blue hue as I am cooking. Will be looking for something different or go back to incondecent until more companies start making the little lights.

    Halo (among other) makes LED recessed lights that have selectable color temperatures. If you're not sure what color temp you want, you can buy these lights and just flip a switch on the lights to set or change the color temperature. These are 4" but 6" are also available:
