    Great LED option
  

*by R***C on Reviewed in the United States on March 17, 2015*

Great LED option. Color is the closest to incandescent that I've found without being incandescent. Similar 360 degree light dispersal as incandescent. I'm using these in my outdoor carriage lamps and post lamp where the bulbs are visible.

    Future for LED's is bright
  

*by B***N on Reviewed in the United States on January 22, 2015*

VERY Nice LED, this technology is amazing.  These are the future of LED lighting.  Hope to see more options or even a filament frosted bulb option soon.  I know that defeats the purpose but read on below for the advantages of the filament bulb over the array bulb.LED Filament vs LED Array Bulbs+ Efficiency... Lumens per watt ratio is an AMAZING 112.5 l/w.  Most LED array bulbs are 60-80 l/w range+ Weight/Size of the filament bulb is much close to an incandescent, i had some lamps array LED bulbs wouldn't fit in+ True 360 Directional vs the Omni directional array bulbs+ Fashionable, we have a couple fixtures my wife insisted on keeping clear bulbs in, now they have theseAlso has all the + of all LED bulbs, longer life, no mecury, no UV radiationWhy not 5 Stars?!- Dimmable option is required especially for these types of bulbs, i tried them on a dimmer they just flicker- CRI is standard 80-82 like most LED's, I'd like a 90+ CRI option

    Long lasting
  

*by S***E on Reviewed in the United States on August 22, 2018*

I've had two of these bulbs in my porch fixtures for almost 4 years now, running for at least 6-8 hours every night. I was having to replace the conventional bulbs way too often, in light fixtures that are not easy to get to. These solved that problem perfectly. The light output is a very good match for 40 watt incandescent bulbs.
