Question: Which bulb color is it?????  Description says 3000k but the pictures shows it's a 4000k.  Trying to match other led I have. This info iOS important
Document: Extremely white and bright. We use it on our art table. Good lighting is very important for color reproduction. WOW!! !
Of course that is if the dimmer and lights don't fail before then. I am trying my 3rd dimmer but it isn't on the list and I expect it to be unsatisfactory. I have other LED bulbs that are satisfactory on standard incandescent, leading edge dimmers, but no other satisfactory G25 bulb is available.
I've tried various bulbs from Feit that simply do not shed warm light even though the packaging says otherwise. This 3M bulb however is one of the few LED bulbs that actually does look warm to my eyes. Unfortunately, I can get a three pack of of other brands for this price! I appreciate that this bulb is assembled in the U.S. but this bulb should be about half the price right now to make it worth it. No way in hades am I going to outfit my 6-bulb dining room light with these for $120.
While I love how bright it is the color is not &#34;right&#34;. During the day it is not noticable at all, but at night it has that weird look all the bulbs seem to have. It definately is not an incandescent bulb, but it is not bad. It is good enough that it will not end up in the box in the garage, but I am still on the look out for the perfect bulb. Maybe I am just too picky.
Now you might very well get away with that depending on the size and design of the particular fixture, ventilation around it, and the ambient temperature and everything. But I see it as a CYA move... you might have a fixture that would cause the bulb to overheat so they just issue a blanket "no enclosed fixture" statement even if it might be fine in some/many/most fixtures. Note this all applies to CFLs as well... they can overheat in enclosed fixtures as well which will shorten their lifespan.- While this looks better than a twisty CFL bulb, I would rather use an incandescent or halogen in a fixture that has exposed bulbs if appearance is important.???:?
This bulb has the closest color temperature of a clear bulb that I have found; only without the harsh shadows a clear bulb would usually give. This bulb is great for table lamps and bathroom vanity fixtures. The whole globe lights up so it does not look weird behind a translucent shade or in a bare fixture. It has a no-delay start up (from switching on to when the actual light comes on). A main concern is that it is heavy. It will make a desk lamp top heavy if it does not have much weighted support at the base.
I'm not sure how the dimming is, but like many LED's, it will probably stay the same color as the light is dimmed. This bulb is also assembled in the USA, making it one of the least expensive replacements that is assembled here, compared to the Philips L-Prize. The ideal fixtures for this bulb is where it has sufficient air flow around it to prevent overheating; recessed and enclosed ceiling mount fixtures are a no no. I have not found a published CRI rating, but rumor has it at 80+.-Update March 11, 2014-Testing three bulbs I have on a P3 Kill A Watt meter, they averaged 16.8-17 watts at 123V; 3.5 watts higher than stated.
Excellent light color and output. No heat build up has been noticed. Currently have three and I will buy more.
Lights are incredibly bright. Running four of them in a bathroom mirror light fixture that almost require sun glasses to be around. Wife says they are too bright but I am warming up to them.Do have an issue with using them in a ceiling fan and a dimmer. Originally thinking it was a dimmer issue (Leviton 6674-P0I LED and CFL Incandescent Dimmer, 150-watt,) but in hindsight could be the bulbs. Not sure how I could determine which one is causing the issue of not dimming smoothly and not getting instant on...Knocking it one star for not playing nice with the dimmer.
Time will tell and I'll be sure to modify this review if the bulb burns out or dims prematurely... however I'm not expecting anything like that from a 3M product as they are usually well made products.Oh yeah.. made in the USA.Cheap CCFL bulbs can be had that also put out a nice, warm light for under 5 bucks each at your local wally-fart so is this a must purchase? Probably not at this point... I bought it just because I wanted to try an LED bulb, and wanted the best.However based on my experience ccfl bulbs last nowhere near as long as advertised because they don't like being turned on and off frequently so I plan to replace all ccfl bulbs with led at some point.
Answer: no
