Like others say, this 10 watt bulb is impressively bright for its wattage, giving off light much like a 100 watt bulb or 20 watt CFL. It is a fair bit brighter than a 16 watt Philips CFL I compared with and the light given off is a little whiter.
The light is fairly directional, throwing very little light towards the base. This means the bulb produces harsher shadows than a CFL or regular incandescent bulb, but useful in down-facing outdoor fixtures where most of the light is directed towards the ground. Unlike a CFL bulb, this LED bulb lights up at full brightness, which is very useful in unheated rooms and outdoor fixtures where CFLs take a few minutes of warming up to give off any useful light.
So why my poor star rating?
I bought 4 Lighting EVER LED bulbs on the 3rd March - two of these, a 6 watt B22 A55 and a 6 watt E27 A55. The 6 watt E27 bulb arrived shattered and the 6 watt B22 bulb failed after a few minutes of use. I was able to return these through Amazon's return process.
Just over a week ago, one of the 10 watt LED bulbs failed. Amazon said I must contact the manufacturer as it was outside the 30-day return period. So I tried contacting Lighting EVER. It's now a week since I made the return request and I have not heard back from them since.
I could not find any mention of a warranty period, so I suspect that its warranty is the same as buying an incandescent bulb. This is totally unacceptable for an expensive bulb (in comparison to CFLs & incandescents) that claims an 18 year life expectancy on the box, considering I just have one working LED bulb left out of the 4 I bought 2 months ago.
Update 17th May 2013: The last remaining bulb has failed. :(
