What is the rendering temperature of the bulb in Kelvin?

Hi, First I need to catch my breath, since my light is high over the sink, and I had to climb up and take off the diffuser. OK: it's 3,000 K. Hope that this helps.

Can not help bought this for my son. You might try using Google by searching for 105w cfl. Will need to know the Kelvin temperature of the Bulb like 6500k or 5000k.

I haven't discovered the temp limit but am using these in the Paradise GL22724BK Low-Voltage Cast-Aluminum, which is a sealed system spot light housing for over a year now...works very well...no degradation in illumination or color

Im pretty sure all LEDs lose lumens over time. Not enough to really notice. Lumens are the amount of light they put out. 3000 and 4000 k is kelvin which is the color temperature. The 4000k always put out more lumens per watt no matter what led it is. LEDs are naturally blue and they add tint to get them an incandescent color.

Silverstars especially the high end HID equivalent are brighter than these. All light output in this type is usually rated in Kelvin. The hotter the burn of the light source the higher the Kelvin (usually) all meant to be toward 5000 to 6000 Kelvin or natural sunlight temps/light equivalent. In my opinion, the Phillips cast a cooler blue light usually associated with a 3500 to 40000 Kelvin scale. I ran them for about 3 weeks and went back to Silverstar HID equivalent for these very dark, no street lights, out in the country roads.

Am not absolutely certain of color temperature, but believe it to be about 5000K, which is whiter than the "warm white". I prefer this higher temperature for reading, and have been very happy with these fluorescent replacements.

Was curious about this myself, so I measured the temperature with my infrared thermometer. The base of the bulb got surprisingly warm given the 4.5 watts, and measured around 150 degrees F or so. For reference, the 40w incandescent bulbs they replaced got to about 260 degrees F. So noticeably cooler, but still warmer than I expected.

The CFL bulb size is that of a standard medium base light bulb if the wattage is generally less than 150--higher and it is a bigger mogul base. The Kelvin range for these is usually over 4000 Kelvin making them a bright white.

Its what you are referring to as harsh white. Its a very high color temperature, although I dont know the exact number, I could say its about like 6000 Kelvin LEDs. And the light output is very high, brighter than my 50 w halogens which it replaced.

I'm only guessing, but aroound 35 to 45 degrees. I have two mounted on a single wall to illuminate my shop and they work OK, NOT great!

Hi J....I measured the temp at the base of the bulb where the heat synches are and it was consistent at about 135 degrees. The bulb itself was warm to the touch. A typical Edison bulb would burn your hand if the bulb was touched. If you are using the bulb in a lamp it will not effect the bulb in the least. However the back of the package states that you should not use the bulb in a totally enclosed fixture. Hope this helps.

Tim is asking what the color temperature of the light emitted is. Not the actual physical temperature of the lights.

LED bulbs should have no problems working down to 0F (-18C). As to the higher temperature, 100F (38C) is not a big deal for any consumer-grade products. Plus you probably won't use the light during a hot sunny day, anyway.

5000k or 3000k determines the color of the light output of a bulb. Lower numbers, like 3000K, produce a yellower light; higher numbers like 5000K produces a bluer light. (k=Kelvin)

Not sure of the exact temp. But it's pretty darn close to all fluorescent lighting

I tested it on a lightbulb and it goes into the 200F range then the display goes to something that says "HI" and I have not gotten it below 45 degrees

I received the bulb as it is pictured ( too bad they did not ROTATE it to show the labeling. ) 110 - 130V 50/60Hz 60 W 5500 K MADE in CHINA 13108 WORKS GREAT !
