Question: Would this work in a lighted makeup mirror that needs a t bulb? Is it bright?
Document: I will update my review if I find out otherwise.As an aside I am trying to switch all my lighting needs to LED for both the obvious electricity savings, and the not-so-obvious fact that with lower energy bulbs my A/C will work less in the warmer months due to far less waste heat from incandescents. I am sampling various LED bulbs for various household uses.
They are not as bright as the first. Maybe I ordered the 7w the second time and the 14w the first...07/14/13 UPDATEOne of the light bulbs died. I was expecting 8 years but only got 4 months of usage out of the bulb. I am going to give it the chance that this ONE bulb was defective. I purchased 10 and only one failed. The one that failed is the one that flickered. Unfortunately, I'm out the money for the one dead bulb. I now wish as soon as I saw it flicker I would have returned the one bulb.10/04/13 UPDATEI purchased 4 more.
This is a good, bright light. It needs to be indirect or shaded, because the LEDs produce brilliant points of light around the shaft of it, and looking directly at it is unpleasant. I use it in a bedside floor lamp and it is ideal for this. No complaints!
I never liked changing bulbs in hard to reach places like closets, etc. Well that's where I used this lamp. It serves the purpose I got it for perfectly.It's not quite as bright as I thought it would be, hence only 4 out of 5 stars, but there is NO heat and they don't burn out like incandescent lights, so yeah, I would buy it again.
I have had these installed in my outdoor light fixtures for about 2 months now. They are great! Bright white lights. They say that LEDs do not attract bugs. That's not entirely true. However, they do attract less bugs than CFLs or regular incandescent bulbs. Also, if you have a non-LED light source anywhere near by, like I do, the bugs show up for that and find the LED lights too. So don't expect to rid yourself of bugs entirely. These corncob style lights work well and cast a wide, even light.
This is a good general purpose light bulb and I would recommend it for applications where the bulb is not seen but light is needed from all directions.
Taking the first one apart a bit, I determined early on that the solder joints aren't great - somehow they seem to fail over time. I could probably take the bulb apart and find the failure with a multimeter and fix it with a soldering iron, but I shouldn't have to do that. If the reliability was there for them to last the 5-10 years I'd expect with LEDs, this would easily be a 5 star review. But reliability is one of the prime concerns with these bulbs.
Ordered 2 of them to replace some CFL bulbs in a bathroom vanity fixture. The first bulb died within a couple weeks and Amazon (or the seller, can't remember) credited me the cost. Not a big deal. Put an incandescent back in and had everything going fine for the last 9 months or so. Then in the last week the LED bulb stopped working intermittently. At first twisting the bulb would bring it back to life, but now it is completely dead. This is the same failure mode as the first bulb.
I always have issue trying to figure out the wattage i need...These work great but wish i had bought something with a bit more intensity...Plan a getting a few more for specific spots or lamps that use more than one bulb, but for situations were you use only one id go with something with a bit more watts! !
These bulbs work well but are not that good for lamps where you can see the bulb, best used in ones with shades. I have one outside in my motion-activated garage light and one inside in a timer-controlled lamp so the savings in wattage is great for these applications. The light output is good for both locations.
Answer: yes
