| Hello all. I am looking to consider LED bulbs for my foyer chandelier, mostly so I don't have to think about replacing them too often since the foyer is 2 stories high.
The chandelier I have will easily hide the bulb behind heavily "crackled" glass, so I'm not too concerned about that. What I am concerned about is light. The chandelier says it uses candelabra bulbs (don't care about fancy tip) that are 60w each. One chandelier uses 10 bulbs, the other uses 16. So far I've only seen (polar-ray, of course) leds that replace 30w bulbs, and I'm concerned that won't be enough light in the foyer because of the foyer size. Any thoughts on the light that would be emitted with the 30w replacement LEDs, and/or where can I find candelabra LEDs that replace 60w bulbs? Thank you! |

| 60 watt LED candelabra replacements are not yet commercially available. There are LEDs available today that produce > 200 lumens per watt, but most commercial products (excluding flash lights) still produce < 80 lumens per watt. |

| Hi again Imacurvygrrl, I just posted in another thread about candleabra bulbs as well, and one thing I forgot to mention that may be worth pointing out is you might find bulbs higher than 30W equivalent but the color temperature of the bulbs may be too high. Typically LED bulbs are more efficient at higher color temperatures (think more lumens/watt, which at the same wattage would equate to being brighter). So you might find someone touting a candelabra bulb as 50 or 60 watt equivalent, but it may be in the 4000-5500K color temperature range which is probably not what you want when dealing with candelabra bulbs. It seems most people still prefer a little warmth in the color temperature of candelabras and that means staying in the 3200K or less range. |

| Thank you David and Sean. If we stick with the lower lumens and the "warm" light, do you think there will be enough light emitted for a large foyer area? One of the lights has 16 bulbs, but the foyer area is 8'w x 13'd and two stories (18'+ high). The glass on the chandelier is heavily crackled and somewhat thick, so I worry it won't be enough light. Thanks! |

| We tried two different candelabra based LEDs in our chandelier. This version was the best. Prior we were only using 15W incandescents so this may not provide enough light for you. However, the manufacturer rates them as a 40W equivalent which I find realistic. |

| Hmmm... only 75 CRI, do they give off good light? Also 3000K rather than incandescent-like 2700K. I'd be reluctant to use them indoors based on their specs. Has anyone used the Philips 3w candelabra bulb? A reasonable 136 lumens, 2700K, and (unlike the Kimberly bulb above) uses clear glass so it will look like a glowing filament in an incandescent bulb. Seems like a reasonable replacement for a 25w bulb in some instances. Some Philips LED bulbs are flickery though, don't know about this one.

| We tried the Philips candelabra based LED and found the color to be fine, but the light output was very weak compared to the Kimberly. The Kimberly we opted for is clear though I believe a frosted version is available. They sit inside of a glass shade so the aesthetics are not an issue. For this application, the CRI is fine. |

| Do the clear Kimberly candelabra bulbs look like incandescents if they were visible (i.e. in a clear glass chandelier or outdoor fixture) when illuminated? They don't look as though they would be in the picture. Also, what are "SMD" LEDs? They use 27 of them, whatever they are. The bottom of the PDF page has a Cree logo - are SMDs a Cree product? |

| Thanks everyone! I saw those Kimberly bulbs but had never heard of them and didn't understand all the technical details as Lee676 was talking about. I assumed if they were Cree that Polar-Ray.com would carry them, but I didn't see them on that site. As much as I want to do LEDs for the chandeliers for longevity, I am concerned they won't give off enough light. I may have to try to find "long life" incandescent candelabra bulbs instead. LOL And then hope when they need to be replaced, there will be newer LED technology to replace them! |

| SMD is an acronym for Surface Mount Devices. It is not confined to CREE. The bulk of LED chips and other chips (e.g. - CPUs) today are produced as SMDs. If you're willing to make your own lights, the LED technology is already available today. Cree has demonstrated 150 lumen / watt prototype lamps and LED chips that achieve ~ 230 lumens per watt. They hope that other manufacturers (e.g. - GE and others) would be able to utilize their chips and designs. It's just that most manufacturers cannot justify the investment. |

The color is comparable to an incandescent, but when lit the bulb itself looks different than an incandescent. The LEDs follow a different pattern than an incandescent filament. All in all, we really like the product. It also seems that only the larger distributors carry them. I believe they are popular with architects for commercial applications or so I have been told. |

| Thanks OP and responders for the info. It has been very helpful to me and my same situation. s-one |
|
| Anyone had some experience with this new bulb? It has a bit higher CRI and is also dimmable. |
|
| Are you using 60W bulbs now? Are they on a dimmer? That's almost 1000W of lighting (960)! It's hard for me to imagine a home foyer that needs that much lighting power. My dining room chandelier has 25W krypton bulbs and we would only have it at full power for cleaning or such. For dining, the light would be too hardh, so it is usually dimmed. Sorry, the candelabra bulbs are the one place I haven't gone to LEDS yet, so I can't help with particular bulbs other than to say I question whether you really need 60W bulbs. We replaced outdoor cans with 65W equivalents and they are providing better light than the 75W and 90W incandescent bulbs were. I have halogen in my lanterns by the front door and krypton in our indoor chandeliers -- nothing over 25W. By the time these need replacement, I hope we have more options and better pricing. |
