A22131CA1-R Classic A19 LED Light Bulb with 60-Watt Replacement and Clear Lens, Soft White (2700K)

LOVE these bulbs... They are glass and are substantial to hold. I loved the look of clear incandescents so the switch to fluorescents was a hard sell for me. Now with the LED options, most lights are stark - These give off a bright, but not blinding light. I tend to prefer daylight bulbs or light in the middle of the color spectrum (rather than true WARM or COOL light). I like both the WARM and COOL versions of SWITCH bulbs as both are more moderate than extreme on the spectrum. They have a significant lifespan and cost just pennies to run per year. I am slowly changing all of our bulbs over...

I bought this to try to replace some Edison bulbs in decorative light fixtures. This is definitely NOT a modern, cool replacement for the ambiance of an Edison. This bulb is BRIGHT white, not the warm white advertised. It dims but goes from bright to brighter and definitely not down low. I'm disappointed. It looks cool but the LEDs are way too bright to be used in a decorative application. Maybe behind a lampshade it could be serviceable but when I tried that it was still way too bright and white for my taste. It just doesn't dim any more than 75% of full on power.

I'm in the middle of changing all of the light fixtures in my house to energy efficient bulbs. I mostly skipped using CFLs except in closets and other rarely used locations because I was never satisfied with the color quality.Now that LED bulbs have become bright enough and affordable enough I've begun using them in applications where I was never willing to use CFL bulbs. The SWITCH series of lights has become my primary bulb of choice for enclosed fixtures. Most LED bulbs are only recommended for use in open fixtures. Although LED bulbs generate far less heat than incandescent bulbs, the LEDs are much more sensitive to heat. While any LED bulb can be installed in an enclosed fixture if it fits, it is more likely to age and dim prematurely instead of lasting it's full rated lifetime (usually somewhere above 20 years at 3 hours a day) if it is not rated for use in enclosed fixtures.The SWITCH bulbs with their liquid cooling technology are rated to be used in enclosed fixtures. I have found that they get warm all over when on for a long period of time. The glass bulb gets noticeably warm whereas other LED bulbs seem to emit heat primarily from the heat sink fins, rather than uniformly everywhere. I take this as an indication that the SWITCH bulb design is more efficient at distributing heat throughout the device, and therefore is probably also more efficient at keeping the LEDs cool enough to operate well.Besides energy efficiency, the most important characteristics to me about an energy efficient light bulbs are light distribution and light color. This bulb has very good light distribution. It distributes light in almost the same way as a traditional incandescent: in all directions. It is slightly brighter around the "equator" of the bulb, mostly this is only noticeable when looking at the bare bulb. I'm less satisfied with the color of the light emitted by the SWITCH. To my eye this bulb is slightly more "brown" than my preferred bulbs. It isn't as unpleasant as CFLs, but it is not as pleasing as an incandescent bulb or other models of LED bulb. For this reason I am going to be using this bulb only for recessed fixtures where I have fewer choices.The SWITCH bulbs turn on very quickly. The delay is almost unnoticeable, even when compared to an incandescent. Some LED bulbs have a noticeable delay that can be especially annoying when combined with other types of light sources on the same switch.The SWITCH bulb is quite heavy. Heavier than any other LED bulb I have encountered. They seem to be sturdily built. I accidentally dropped one from standing height onto a hardwood floor and no damage occurred. The weight may be a concern in certain fixtures. In one of my flushmount fixtures intended for incandescent bulbs the bulbs droop several inches because of the flimsy and flexible metal tab that supports the socket. I used a zip tie to reinforce the socket mount so it could support the weight of these bulbs.PROS:Rated for use in enclosed fixturesInstant-on360 degree light distribution patternSimilar size to a 60 watt incandescentCONSExpensiveHeavyAverage color qualityFor reference, I prefer the color from Philips AmblientLED bulbs as well as CREE LR6 and CR6 cans.

I won't attempt to outdo Demanding Customer, who has given an extensive review of this bulb. I will say, however, that I'm extremely pleased with this bulb. It works in any orientation, and the liquid cooling allows it to safely operate in enclosed fixtures. The placement of the LEDs does create a bright ring around the bulb -- this may or may not be an issue with your application (for us, it isn't). The light does evenly disperse from the bulb, however.One caveat is that color rendering is not as optimal as with incandescent or halogen lamps. It's far better than the typical CFL and its white temperature is close to halogen. But colors do lose some intensity -- which is why I've rated it as 4 stars instead of 5.

Other than the single issue (see below), I have 4 of these bulbs, and they work great. I've had 2 of them in an open topped chandelier, running 24/7 for over a year and a half, and they're still running strong with no problems. I keep my house at 70 degrees f, and you can walk up to the bulb that has been running continuously, and hold the glass with your bare hand indefinitely, the metal heatsink you can touch for about 15 seconds before it gets uncomfortably hot. I have one in a recessed ceiling light with an open bottom (where the light shines out), and I only turn that one one occassionally, not usually for more than a few hours about twice per month, but I have not had any problems with that one either. However, when it has been running for a several hours, the glass is too hot to touch, so that probably means that any prolonged usage in a poorly ventilated housing like that would decrease the lifespan, but that's just speculation, it could be just fine.The Single Issue: I bought 4 of these at the same time; when the shipment arrived, one of them had an air bubble in the cooling liquid (this is bad, if you get one like that, return it for a replacement; don't use it). I sent it back, and got a replacement quick & easy. The replacement was perfect just like the other 3 from the original order. I don't have a problem with this; as I said, the replacement was in perfect condition like the other ones, and there will always be the occasional manufacturing defect; most of this stuff is automated, they can't catch everything. It's not a big deal, just send it back and get a new one. It's kind of annoying, but not really that bad.

I bought this for use in an enclosed fixture. My ceiling fixtures have ridged glass, and the light from these bulbs creates a very noticeable pattern of light that other bulbs don't. I found other fixtures to put them in, not enclosed. I could have used any bulb for that application, but I'm glad I found a use for them.
