Great bulbs - no shadows cast on lampshades

One of the downsides of most LED bulbs is that the housing that houses the electronics protrudes halfway over the bulb, creating unsightly shadows on glass covered lampshades and fixtures. These Sylvania lamps mimic an incandescent lamp much better. No more strange shadows on the shadows. The only downside is that Revain doesn't always carefully pack these bulbs for shipping. In my last order of six lamps, three broke because the Sylvania box slipped into the main box, which also contained…

Pros
  • Few competitors
Cons

Be careful - some of these "dimmable " lamps are not dimmable.

I ordered SYLVANIA 40813 LED A19 60W Equivalent, DIMMABLE, Soft White Bulbs. What I received was the equivalent of SYLVANIA 40821 LED A19 60W, no dimming, soft white bulbs. They flicker pretty badly with a dimmer. I have bought lamps of the same model in 75w and 100w versions with the same dimmer with no problems.

Pros
  • Great for a small home
Cons
  • Questionable purchase for the elderly

Nice warm light like tungsten

I usually use 5000K LED bulbs but wanted some with a 'warmer' 2700K light that looks more like old tungsten bulbs. They provide excellent quality warm light after being heated. Dimming works very well, with no hesitation, gaps or buzzing, using a traditional non-electronic dimmer switch. They also have a very small base and are short, making them suitable for lamps where many LED bulbs will not fit. I have several lanterns with calfskin lampshades, and regular tungsten bulbs would fry and…

Pros
  • Delivery was very quick
Cons
  • Crumpled
