I purchased this Philips SlimStyle 13W A21 LED 2700K Dimmable Bulb from my local HarDware store, because I need something brighter than the typical 60W-equivalent 800 lumen LED bulbs. Previously I tried the LE 12W A60 E26 LED Light Bulbs which claims to be '75W-equivalent' with a light output of 1010 lm. But once the bulb heats up, it's light output drops to just '60W-equivalent'. This Philips SlimStyle A21 bulb, on the other hand, seems to give out a consistent 1100 lumens of light whether it is cold or warm.[Physical Appearance]The Philips Slim-Style A21 bulb is flat and shaped like a lollipop, just like the smaller A19 version (Philips 433227 10.5-watt Slim Style LED Bulb) which I reviewed more than one year ago. The bulb is covered by a thick, semi-translucence plastic which makes it feel rugged. The plastic is thermally conductive, to get the heat out of the flat heat sink in the center.[Beam Pattern]The actual light source consists of ~40 tiny LEDs, arranged around the edge of the lollipop. This gives a very uniform light distribution, close to omni-directional like a traditional incandescent bulb.The color temperature is 2700K, which is similar to that of an incandescent bulb. So unless you can see the bulb directly, you cannot tell the difference between this LED bulb and a 75W incandescent bulb.[Power Consumption]According to my EUM-A1 Power Usage Meter (which has a resolution of 0.1W), the Philips bulb consumes 12.6W, initially. After ~30 minutes, the power remains nearly unchanged at 12.5W. After more than 1 hour, it settled at 12.3W. This is much better regulation compared to some other LED bulbs I have tested. (The LE 12W LED bulb, for example, dropped from 11.6W to 9.6W in just 30 minutes)The power factor is consistently high at PF=0.88 - 0.89. This is usually a sign of good electric design.[Dimming Performance]I tested this Slim Style A21 13W bulb on a TRIAC-controlled light fixture, together with three other Philips LED bulbs:- Philips 433227 10.5-watt Slim Style LED Bulb- Philips 432732 11-watt A19 LED Bulb- Philips 455576 60-Watt Equivalent A19 LED Light BulbAs can be seen from the customer image I uploaded: both Slim Style bulbs show very limited dimming range, down to maybe 20% light at minimum power. However, there is one very important difference not shown in the picture: the old A19 Slim Style bulb gives out a loud buzzing sound when dimmed, while the new A21 bulb is almost inaudible.In term of dimming range, the Philips 432732 11-watt A19 LED Bulb is the clear winner. It dims all the way down to a faint glow.The Philips 455576 60-Watt Equivalent A19 LED Light Bulb is clearly labeled as 'Non Dimmable'. But I put it through the test anyway, just because I'm an engineer. As it turns out, its performance is surprisingly good for a 'non dimmable' bulb.[Summary]I'm happy with the extra light output produced by this Philips Slim Style 75W-equivalent LED bulb. Its power consumption is well-regulated, which implies consistent brightness at hot. More importantly, Philips seems to have improved the mechanical construction to eliminate the buzzing sound when dimmed. As of right now, this is the lowest cost 75W-equivalent LED bulb made by a reputable company. That makes it an excellent value.
This a good LED light for many but not all applications. As noted in another view, it's pretty big and may not fit in all lamps. The shortcoming I've found is glare. Glare is the subjective discomfort from looking at a bright light. If you put this bulb in a fixture where the bulb is exposed to look at, then the glare is considerably worse than a similar incandescent or halogen bulb, and worse than some other LEDs. If you compare light bulbs with a similar number of lumens (~1100 for this and similar "75W") bulbs, the glare is worse the more concentrated the light hitting your eye and retina. If a regular size light bulb glows equally all over, when you look at it there is very little glare. If you look at a clear bulb that has a tiny 1100 lumen light source in the center, the glare will be much worse, as the light is very concentrated on one specific part of your retina. This light has multiple point sources around the edges, and while the translucent covering diffuses the light a bit, I and my family still find the glare objectionable compared to other LED bulb designs. I'm only using these in fixtures where the bulb isn't visible. But in other fixtures, where it's not exposed, and where it fits, it's a pretty good bulg.
Very good light source. I was trying to screw one into our porch light outside, about 10 feet above the ground. I dropped it, it crashed onto the steps, then on to hard asphalt, bouncing and spinning all the way. I was delighted to learn that the fall did not harm the bulb in any way that I can determine! Therefore, like turns to Love!
We purchased this bulb to replace the incandescent 72 watt bulbs in our Master Bath, because they were making a very audible "singing" noise that really was irritating to listen to. These new LED bulbs are slightly longer than the bulbs they replaced, so they do protrude a little below the bottom of the globes (which the old bulbs did not), but that isn't really a bad thing because the globes are frosted. With the bulb being slightly below those frosted globes, they probably allow more light to go out into the room, and the "soft" light they emit isn't hard to look at. These bulbs have a really slight audible singing noise, but not noticeable enough to be irritating. I would have rated them at 5 stars if it weren't for the fact that the photo of them on Amazon doesn't show you that they really are a flat bulb (not round like picture makes you think by looking at it), and also because they are a longer bulb than a normal incandescent bulb of similar size. There is a slight delay after flipping the switch. These do not dim as much as the incandescent bulbs they replaced--on the lowest setting of the dimmer switch.
This is the first time I have tried LED bulbs. I was surprised when this bulb came to see that its shape is flat instead of round. The light it gives is just like my old incandescent lighting, soft white. They come on right away after only a very slight hesitation, and give light in all directions (360 degree). I saw from descriptions that some only give light from their upper half, a thing to look out for when deciding which type of bulb to choose.
