EarthLED EvoLux S LED Bulb

I have the Cool White version of this LED lamp (I don't care for the Warm White color).

The brightness is fine, one of the few LED lamps I own that is this bright (900 lumens).  It is also better dispersed than most LED lamps.  But the CFL I replaced with this was in a fixture above head level with the top of the bulb pointed upward, and even though this lamp is brighter, the CFL gave more light downwards, due to the fact that very little light shines downard (below a horizontal plane) from this LED lamp.  So this lamp would be better for applications in which it is pointed downward if the lamp is overhead, unless lighting mostly just the ceiling is sufficient.  Lastly, the fan is not quite silent although it is very quiet.

All in all a decent value considering price/brightness/efficiency/lifetime, you just have to consider the fit with your application closely (as with any replacement LED lamp).

I have been anxiously awaiting the arrival of my Evolux S (I got the warm white model). Even if LEDs are relatively older technology, I'm excited by the new momentum they're getting and all the new applications. The bulb doesn't disappoint in that way - it's relatively futuristic looking and a lot bigger than I was expecting.

I did a comparison with the CFL that I've been using for the last several months by putting the Evolux in my bedside lamp. The quality of the light is fantastic. Similar brightness to the CFL, but warmer and easier on the eyes. It's totally sufficient to read by.

The only downside is there is an audible hum that emanates from the bulb. I don't know if it's the AC to DC transformer or what and the sound is incredibly easy to ignore, but it still warrants mentioning. If the bulb were higher up (like recessed ceiling lighting), I don't think this would be an issue at all.

Also, I have yet to challenge the 50,000 hour life in my first week with the bulb, but I'll keep at it....

I tried this bulb in my reading lamp next to my bed.  Unfortunately I can't recommend it for a quiet location like that.  To me, and maybe I'm too sensitive, the fan noise was too noticeable.  Also, because of the way the base is designed, the light is very directional.  The light was focused out the top of the lamp and almost had a 'spotlight' effect on the ceiling, which wasn't great for reading.  It replaced a CFL that was working well and the lamp just wasn't a good application for this particular bulb.  If you have overhead lighting, I imagine this would be a good option.

We are an Earth LED dealer so I have been beating up on these bulbs for a while now. I have over 5000 hours of use on one, as I hardly shut it off. It still has the same brightness as when it was new. Only a couple more years of constant "on" and we will see how it really does!

The thing I like about these is that you can't break them, and that they work outside in the cold. These are perfect for lamp post that you like to leave on all the time so you have night time lighting when you get home late. 

The downside is that they have a fan to keep them cool. So the question is, will the fan outlast the bulb? I think the chances are good as long as you don't use the bulb in a dusty place. 

I can't wait until they start building these things like the zetalux!  

The Huddler folks let me borrow their EvoLux S bulb for a test drive.  I put it in the overhead light fixture in one of the rooms (small bedroom size) in my house.  The bulb is nice and bright and easily lights up the whole room.  Some other reviews said that the light wasn't diffuse enough, but in the overhead fixture it does light up the whole room pretty effectively.

The light is a little on the white side, but overall has a pretty nice "warm" quality to it.  The one odd aspect is the hum of the fan.  It's not very loud, but can be a little noticeable in the background.  I wouldn't want to use it in a bedside lamp or any light fixture too close to my head - I think the hum might start to irritate me.

Supposedly the bulb lasts for 50,000 hours and only uses 13 watts.  Pretty cool bulb overall.
