Reviews of Sylvania 78952 20-watt A21 Ultra LED

Customer Ratings:

I've been waiting and watching for a 100 watt equivalent LED for a long time.

I already have several Philips LED 75 watt equivalent bulbs.

Unfortunately the Sylvania A21 buzzes loudly and it dims poorly.

On the plus side, the Sylvania bulb is brighter than the Philips A21.

The buzzing noise is much less noticeable on a non dimming circuit.

Light radiates from the bulb top and bottom which is an important new step in the design of LED bulbs.

Dimming appears to be about 65% of full.

Finally, a 100 watt equivalent that works!

The bulb gives off a very bright, omni-directional light, exactly like one would expect from an incandescent.

The heat given off is about the same as a 100 watt incandescent.

I have read a review that talked about the bulb "buzzing", but I do not have any issue like that. I am not using the bulb on any kind of dimmer switch, just a regular on/off.

The *only* caveat with this bulb is its size: A21 instead of A19. Just be sure that it will fit where you hope to use it.

Once the pricing on these bulbs drop, I'll start to use them everywhere.

As expensive as these bulbs were, you would believe their output would be consistent. I bought two of these. One bulb is fairly bright, the other is yellower and significantly less bright. I inspected that all the individual LED's within the bulb are lighting up, but they are simply all less bright. Not sure why.

Honest reviews on Sylvania 78952 20-watt A21 Ultra LED

High price, high lumens, low wattage. It works. Only buy if you're a techno junkie because you won't live long enough for this thing to pay for itself, and they'll be $10 in a couple of years anyway. One quirky thing I like about itwhen you switch the lamp on it dims up. Reminds me of these classy lighting systems that are found in upscale homes with can lights. Also comparable to the undimming of lights at the local cineplex.

Sylvania makes quality LED bulbs and wanting more lumens I tried this bulb. I am satisfied with it. The only comment would be expect it to have a soft start. I am assuming the design is limiting the in-rush current going to the diodes to provide a long life. I can live with that.
