What is the color temperature in K of these lights? Is it over 4500K ?

It's not "pure white" like 4500K, looks like "cool white" that means about 5500K. But looks good specially for some places where you want a bright light instead a non color change light. The pure white version of 5050 LED is difficult to find and is only useful if you want to see colors as a sunlight. The cool white have about 5% to 15% more blue into light spectrum. I have both and honestly, is hard to see the difference if you don't put near enough one from the other.

It is a nice white, light. I would say between 6000k-6500k. It seems about the same as my 20 watt LED light. Probably right around 6300k.

No, these are is listed at 6,000k which puts them at the high end of "daylight". It is really "white". Warm white refers to a color temperature around 3,500k.

Yes this is light has a color rendering index (CRI) of 98 and Temp 6700 (K). Right there on the website.http://www.exo-terra.com/en/products/compact_fluorescent_bulbs.phpHope this helps!!

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.

3200K is more of a blue light.. 1700 and below would be a much warmer light (yellowish).

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.

They come in 4000k at 45 lm 6000k at 52 lm and 6700k at 52 lm. 4000k, 6000k. and 6700k are the color of the light from yellow to white.

Yes, these are standard H8 bulbs, but the actual color temperature is nowhere near the 4150K claimed. I used mine once, and out them right back in the box.

2700 K is the kind of light given by a 60 W "soft white" incandescent; it is slightly yellow. 5000 K is "daylight", which gives a harsher, bright white color tending to blue. 2700 K is good for regular home lighting, while 5000 K is better for office and study spaces or for arts and crafts where accurate color vision is needed.

"k" is the color temp, has nothing to do with lumens or light output. the color will not change with added lights

They are rated for -40c if you look at there specifications , most LED fixture like the cold better than excessive heat.

I can't say the exact temperature but it is not a warm light at all. I would guess around 6000K.

I would say the light is closer to 6500k (more blue than white). I found this annoying because even though I enjoy white light for daily tasks it is too white/blue for me to keep on during the night. It is also a lot brighter than I expected!

They are 3700K, a cri of 90 with 1260 luminaries (this is the amount of color rods that your eyes pick up, hope this helps :) These are great they are full spectrum the coating is what filters out the light bringing it up to 3700, if you take the coating off it would be only 2500k

I have been using mine for 9 months outside in hot and cold weather with no problems. If you haven't noticed, they have three different color temps for the bulbs, make sure they ship your preference. I have the White 6000K and the Warm White 3100K. The 6000K is noticeably brighter, but the light is bluish, similar to the color you might see in a car headlight.

5000k will be bright and I'm sure you'll be just happy with them. I have 6000k and they come out more blue-ish.. Think of it this way. 5000k are like white with a hint of blue. 6000k are like blue with a hint of white. However they are both extremely brighter then what you have now. So it really depends on the look your going for.
