LE® 5W Dimmable C37 E12 LED Bulbs, 40W Incandescent Bulbs Equivalent, UL Listed, Candelabra Bulbs, 350lm, 120° Beam Angle, Warm White, 2700K, LED Candle Bulbs, LED Light Bulbs

I bought these as a replacement for some CFLs that we had, they were getting old and took progressively longer to warm up so it was time for replacement. I went with LED because there is no warm up and they are actually comparable in price whereas before they were at least twice as much.Pros*No wait time like you have with CFLs*Instant on, I know I mentioned no wait but literally they are instant. I bought some other LEDs from a local store and they have a short delay. While I've gotten used to the slight delay with the other bulbs, it still bugs me. These are great, literally as the switch is flicked BAM!*Less energy, CFLs equivalent are about 9W and obviously incandescent are 40W. I highly doubt you will see the difference in your bill changing from CFLs but less wattage means less heat. I can take these bulbs out after being on for hours, I could do the same with the CFLs but I had to only touch the tips as the base was very hot.*Cheap, these aren't 50 cents a bulb like incandescence but hey, a couple bucks for a bulb that may outlast your fixture isn't bad, you won't have to keep an inventory of bulbs for quick replacement either.*Won't break and definitely no chemicals to worry about (CFLs contain mercury which releases when broken)Cons*As many of the reviews have stated, the light is very directed and the diffuser does not do well at spreading that light around the room. It is also very bright more directly at the point of the bulb than it is looking at it from the side. This may not be an issue for you if you have upward pointing fixtures because in this case because your ceiling will likely diffuse the light for you. My fixtures are angled downward so for me I did not like these bulbs as they are, I modified them and now they're perfect, see below.*Not a con for me but it is for some so I'll list it, the black lettering is very visible and not so pretty if you have a fixture with the base of the bulb showing.*Brighter than you may expect, I didn't only find this with these bulbs but I had bought some CFLs before with the same issue. I believe the flaw with these bulb ratings are that they are likely designed for a fixture with upward pointing bulbs where the light is meant to be diffused by the ceiling. When you have these pointed downward you can see a ring on your wall and a spotlight effect from the bulb's internal diffuser.I was able to get these to work perfectly and they are the best candelabra bulbs I have ever purchased. I explain how below...How I solved the light diffusion problem (for even lighting):I bought a $3 can of flat white spray paint from my local hardware store. I taped the base of the bulb to keep the paint off of it but you could likely leave it open and only tape the connector if you don't like the writing as many reviews complained about (then you can paint over the writing also. Anyway, I ever so lightly dusted the clear cone with flat paint, you can actually still see the plastic to some extent so it wasn't much paint at all. I did this with one bulb and compared it to another unpainted... turned just the painted on, then just the unpainted on and then I compared it to my previous bulbs which were CFLs but they had a white cone, they were nearly identical to my original CFLs only they are a little cooler (more white) and no more warm up time.A few other pluses to dusting with paint*You can add a little at a time and try it out, if it's still not what you like, add more.*You can choose a slightly tinted color, brighter white or even slightly (very slightly) tinted blue will give a cooler light while flat or even slightly (very slightly) tinted yellow will give a warmer light.*By adding the layer of paint and diffusing the light, it spreads out more and isn't so directed which lowers their intensity and they represent a typical 40W equivalent instead of being just a tad too bright.DISCLAIMER: I painted mine because I felt that I wouldn't use them and I don't take things back so they were essentially garbage anyway. Also, I only painted one and tried it out. Please do not blame me if you decide to take my advice and it ends poorly for you. This solution worked great for me and many others complained about the spotlight issue so I thought I'd share. Lastly, while I feel there is no potential danger here, some may disagree and I feel you should know anyway, painting the plastic could increase the amount of heat produced which could, in some crazy world present hazards, again I do not feel this is an issue as spray paint can typically withstand up to 200 degrees which is not anywhere near what this LED will produce (LEDs product about 4% of the heat that incandescents produce, 3.4 BTU/Watt vs 85 BTU/Watt). Please paint at your own risk.P.S. I will try to add some photos of my bulbs, unfortunately I didn't take any photos of the comparison, I'm writing this a few months after my purchase.

I just started upgrading our incandescent lights to LED. For the porch light & dining room chandelier, I needed an LED bulb that looks good visually + it had to give off a bright light, close to that of the incandescent bulbs it was replacing. My search for this LED bulb found this.The pros:+ $7.99 + Amazon free shipping when I purchased one to try.+ Pretty good customer product reviews.+ 5 watt LED = 40 watt incandescent equivalent!+ Product dimensions - my measurements: Tip to tip = 3-3/4". Tip to base = 3-1/8". Width at the widest point = 1-3/8".+ Advertised - Less energy wasted to generate heat, compared to an incandescent bulb.+ Advertised - Warm white color, 2700 kelvin.+ Advertised - 350 lumens. VERY bright!+ Advertised - 85 CRI - color rendering index.+ Advertised - Instant on, unlike CFL bulbs.+ Advertised - dimmable... see below for more on this feature.+ Clear bulb look, looks good when used in a fixture where the bulb can be seen.The cons:- Normally 2700 kelvin is considered warm white. The color is a touch cooler... whiter than warm white, guessing 2900-3000 kelvin? Not a bad thing, but some may think the light is too harsh.- These have a C7/E12 base, so I had to buy adapters to fit these where I had standard E26 bulbs.Here's a link to the adapters I purchased:  UL-listed 10pcs Pack E26/E27 to E12 Adapter - Medium Screw (E26/E27) to Candelabra Screw (E12) Socket Reducer Adapter Converter - These won't work with our X-10 home automation WS467 wall switch module. The LED bulb won't turn off completely & it won't respond to dimming commands! :(Closing remarks:This LED bulb is "clear", so the light isn't diffused. This is equivalent to a clear incandescent bulb, meaning the light is bright & on the harsh side. This works best in fixtures like a chandeliers, where the bulb is visible.To get this LED bulb to work with our X-10 home automation wall switch module, I had to modify the module to a SSR, solid state relay. No dimming function with this modification, but in our applications, no dimming is required. The details on this modification can be found on the internet.5 watts = the light of 40 watt incandescent bulbs. I replaced a 25 watt incandescent porch light, so that's a 20 watt savings! :)

Considering the poor quality of many commercially available LEDs, and newer technology lightbulbs in general, I took a big gamble on trying 4 of these. I was overall extremely pleased. I've had these for 3 weeks now and I'll follow-up in a few months.Strengths: - It is bright. It seems to be at least as bright as a 40W replacement. - It is relatively inexpensive. - It appears to be well-made and thoughtfully designed.Weakness: - Most of the light travels in one direction, like a flashlight. There appears to be some sort of a lens here that tries to disperse the light, but I suspect it mainly serves to prevent you from going blind. - The stated color spectrum seems to be way off. It is not comparable, at all, to any "warm white" bulbs I own. I don't have any specialized equipment to measure; I just have my eyes. And my eyes say this is more like a pure white daylight bulb.Bottom line:If color temperature (blue or yellow hue, etc) is not the largest concern to you, then I recommend you go for it and buy these. If it is a concern, then I suggest you shop around for a warm white LED candelabra (and let me know what you find out).
