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....

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!  

I have been testing this bulb out in several locations throughout our home to see how it stacks up in different applications.  In reading the previous reviews, I am finding that all of our experiences are very similar.   In all areas I could hear the fan - some applications it was more pronounced, others not so much.  The "wife test" did not go so great as she asked right away if the noise was always there...

> It works great in an overhead recessed fixture - super light for a room sized area.  I found the fan was a bit amplified as the "can" acts as a directional cone for that slight noise... 

> In a table lamp - the light bulb itself, being kinda tall, set the horizontal light emission sorta high, with virtually no light emitted downward.  Probably not the best application - but a torchere light (points up for indirect light off of ceiling) might work out good if the right shape. 

> Workbench light - fantastic, I don't mind the quite fan noise at my bench.

> Kids room directional light - great, but again, "Daddy, what's that sound?" 

I suppose if I put it in one of my downlights above the stairs about 18' up, the fan would not be of issue at all, but I was a bit frustrated to hear the question over and over... The emitted light (warm white) was really quite good.  Can a fan last 50,000 hours?  If it was somehow silent, this bulb would have even more appeal to the masses.  Great product overall tho - big step forward in LED lighting.
