Approximately how many lumens, and what is the CRI? How does spectrum compare to incandescent? Hoping to get good red content.

Sorry. I don't know. I have a mix of LEDS in my RV and most seem to be as bright or brighter than the incandescent lamps they replaced.

I wouldn't know a lumen from a Newman...but the bulbs work fine in our Motor Home - plenty bright - actually replaced two incandescent bulbs with one of these LED's in the bedroom "beside" lamps. Spectrum is a little "whiter" than the incandescent. I mixed two incandescent and two LED's over the bathroom sink fixture and wife says it's OK for dressing/makeup. I'll be replacing all the bayonet based incandescent bulbs in the future when we start "full timing" on the road and mount a lighted magnification mirror for the wife. Hope that helps.

Hello Light waves, With no spec for lumens or CRI on Amazon, I'm almost as much in the dark (NPI) as you. However, I've had one of these running in a decorative spotlight for a few months, so I can make some comments. The color of the light is much better than a CFL, but not as nice as incandescent or the legendary Philips L-Prize bulb. Comparing it with various Philips and Cree LED bulbs that I'm currently using, I'd say the CRI is probably around 80, certainly no better than that. That's just an eyeball estimate though, YMMV. Brightness is roughly equivalent to a 25-30w incandescent bulb. If you use it in a reflector spotlight (I'm using it in an old boat searchlight - the reason I needed a bulb with a BA15D base) it makes an odd but interesting pattern on the wall because of all those individual LEDs spread over a large area. It doesn't dim very well, even with a PWM dimmer specifically for LED lights. However, after my initial experiments, and given it's modest light output, I never attempt to dim it anymore. You probably already know this, but just in case, be aware that this bulb has a BA15D (both bayonet pins at the same height) base. This means you can put it in the socket backwards and it will not work (I've done this a few times, it didn't destroy the bulb). Many bayonet base LED bulbs on the market use the BAY15D base (pins at different heights), preventing it from being inserted backwards. I have found the descriptions - even on Amazon - to be wrong about the base type occasionally, so always look at the pictures carefully to be sure the base type is what you need.

2700K color temperature and color rendering index of 80 are close to as good as LED bulbs get. To completely match incandescent, LED bulbs will have to reach 2700K and 100 CRI. But I have a number of bulbs with 2700/80 that I am satisfied with in terms of warmth vs incandescent, especially considering the superior bulb life, reduced waste heat output, and lower energy costs.

I didn't measure the power used, so can't comment on that. But mine are *really* bright and I believe the claim that they are equivalent to a 225W incandescent. But they're not instantly bright - they take about 5 minutes to reach full brightness.

Well, I don't know much about CRI but in the bulbs attached reads 85W, 120V, 5500K RoHS, they are big bulbs, i had to replace with 3 bulbs as they got broken, my mistake but replaced with smaller others and have worked fine, i bought like a year ago and i am happy with my lights.

I looked this up and it the 170 lumens is not so. This lantern provides as follows: High for brightest light; 340 lumens; runs 30 hours * Medium for bright light and longer run times; 175 lumens; runs 70 hours * Low provides extended run times for when less light is needed; 33 lumens; runs 295 hours - Red LED (one red LED) * Red LED High - Steady (night vision preserving mode);10 lumens; runs 235 hours * Flash SOS mode for emergency signaling; 10 lumens; runs 430 hours.Bob

Do not have an exact answer but I have purchased two types from the same manufacturer. The first were white light and a bit startling and different from incandescent that I am used to using. I really did not like them. The second purchase was of a warm light variety. Right now they are intermixed with the white light in the fixture. I will buy the warm or reddish light ones in the future. My disappointment in these lights is that three have burned out in the first six months and one lasted less than a week. They have held up better of late. They are in a fixture fed with a dimmer and I wonder if that is the cause of the failures. I am getting better at setting the dimmer slightly off the peak setting where the lights actual want to flicker. Off course I know the dimmer will not work but it is there and sometimes gets set inappropriately. Need to replace it with a regular switch one day.

According to Streamlight's page, this is what I have found "5mm IR LED: 25mW/sr (min) radiant intensity"And how it does compare to the others are hard to say, as I have no IR night vision googgles to see them with, so you might say you cant see it at all : ) You may barely see it with your phone camera, but I do believe it would be different with IR sensitive camera.

My guess would be 75 to 90 lumen, its not super bright, but it is plenty bright enough to light up a dark hallway or parts of your home inside well enough to see pretty good. It does work well but its no Surefire. If your wanting it for use indoors, it should put off enough light for you. It does make a bit more light then those cheapo handgun mini lights.

The light is very bright and has a great warmth and color to it. I don't think there is a noticeable difference to incandescent.

The chinese cree xml 1200 lumens is brighter but not by much. Those claimed 1200 lumens are rubbish although it is still very bright, its closer to 700 lumens and the optics are way superior con the cygolite. The cygolite is more trustworthy, realiability on those generic chinese lights is a crapshoot, especially with the battery. I have both.

Lumins don't seem to mean much as far as brightness. I finally went by colortemp. Higher the temp the brighter. I just used a dimmer.

John - Sorry I can't tell you the lux output. It was advertised as full spectrum light and puts out approx 1400 lumins. Hope that helps.

The cfl which comes with this item is equivalent to a 60 W incandescent light. However, I replaced it with an LED light bulb which is brighter. The bulb I chose was a "Kobi Electric LED 15-Watt (75-Watt) A19 Warm White Light Bulb" available through Amazon. This bulb is brighter, uses about the same amount of power, and it comes on instantly just like an incandescent bulb. The bulb burns brightly, but you can touch it a few minutes after you have turned it on and it feels barely warm. Almost all the energy goes into producing light, rather than heat.

It's a little over 100 lumens. Those who wrote 200 and 300, are only comparing output to generic lights that are fraudulently rated higher than their actual output.

As one who is getting older also I find that 750 lumens, the only real measure is adequate for general work but not detail. I use them to reduce energy cost and A/C but still miss my 85 watt incandescants.

CRI is on a scale of 0 to 100. 2800 is impossible and must be the color temperature in degrees kelvin. That said, I'd like to know the CRI (color rendering index too). 100 means that colors appear just as natural and correct as they do under an incandescent light bulb ... most LEDs are less than 90, with the best ones being at or above 90.

I cannot speak to the lumens, the description says 15. The light is bright, more like a 7-10W equivalent than the typical 4W, and is closer to daylight than warm white. Its light is white, not that golden hue so many bulbs give off. There are 6 LEDs in a 2x3 array. I hope this helps. I have a bulb burning inside a quartz crystal lamp that has been burning continuously since December 3, 2013. The crystal does not heat up like it used to with the regular bulbs, even though the lamp is never turned off. I would by these again.
