5.0 out of 5 stars The *best* value if you prefer natural color to a yellowed incandescent simulation called "warm" October 4, 2011

By Robert Clayton Barnes

I'm astounded there are no reviews yet, so here's mine:

These bulbs let me to begin my long-awaited transition to LEDs. If you can't cope with the color balance (modeled after the sun under "normal" weather conditions), you can always pick the "warm" model that simulates the particular color we've grown to tolerate from most traditional incandescents. If you can, and I highly recommend you try, there's no better LED bulb on Amazon (or the 'net so far as I've seen).

The size is extremely similar to a traditional bulb, bigger or smaller by a few millimeters depending on where you measure. Though it looks plastic, the bottom feels like ceramic or painted metal or such; expect significantly more weight than the thin-walled vacuum you're replacing but I have trouble thinking of anywhere that this difference would matter. The manufacture has videos of various physical abuses of the bulb (dropping onto concrete, etc.) that I haven't the nerve to verify, but presumably the new materials confer substantial durability.

<REDACTED>
On the topic of durability, these bulbs run very cool, so they're actually safe to stick in enclosed fixtures. I have, in my ignorance, used mercury florescent bulbs in closed lights, not realizing the heat builds well past operating spec and destroys the bulbs rapidly; aside from LEDs, only incandescents are designed to safely work in closed lights.
</REDACTED>

EDIT #2: In my enthusiasm, I was not accurate about the safety of LEDs in enclosures. While these run significantly cooler than other bulbs (about half the waste heat of florescent bulbs), they are not strictly designed for sealed enclosures. While my fixtures were able to radiate more than enough heat to keep my LEDs safe, your mileage may vary; I have an IR thermometer that I can use to test operating temperatures but without one, I would only try these in an fully sealed fixture if you're okay with possibly burning a bulb out from the experiment. My sincerest apologies to anyone who was mislead by my previous revision.

Though the light is significantly more directional with this bulb than other designs, I like that, even for general use because of how I light a room (I suggest you try my setup even if you don't switch to directional bulbs): I place several strong light sources around the room (but behind bookshelves, thick lampshades, etc.) with the illumination directed at white walls and/or the ceiling. The paint acts as a diffuser, causing the overall effect to be gentle, comfortable illumination without overly bright or significantly shadowed.

Of course, the best part about these bulbs... is the price. I was skeptical that they could be any good when placing my first order. Well, they are good. VERY good. So much so that I almost didn't install the second of my two lights before logging on to order quite a few more!

In short, I'm extremely pleased and plan to buy enough to phase all my bulbs to these as soon as I can manage!

EDIT: For those of you who don't realize this property of LEDs, they *can* be dimmed! Those sockets that have the continuous brightness controls are finally useful again (they were the last begrudging incandescent hold-outs for me). Note that these aren't 3-way bulbs, where you click between four discrete levels off/low/medium/bright; those are a special kind of bulb with two independent light sources that are activated in various combinations to produce three levels of 'on.' These LED bulbs will produce light in such sockets, but, like other single-circuit ("normal") bulbs, the result will be that instead of off->dim->medium->bright four clicks will produce off->off->on->on.

5.0 out of 5 stars LEDs are the best way to light up your life October 7, 2011

By Lyle

I too am in transition of switching from cfl to led. More light, less current draw better coloring (I prefer the whiteness over yellow) Try it-you will like it. Save on electricity costs and replacement cost-lasts much longer than cfl. Bought some locally as well but paid 3X more than EarhLED. I got it shipped for free and it took a little over a week. Auwesome company with a great product, and when paired with Amazon-it doesn't get any better. ALOHA

5.0 out of 5 stars 7 Watt - Cool White (5000K) November 8, 2011

By Infusion

1. Bright
2. Cool white(5000K)is a bit warmer/more pleasant than 6000K bulb (to me)
3. Instant on, no hum, no flicker & it runs rather cool
4. Heavier than "regular" bulbs (top is diffused hard white plastic)
5. I use 2 of them (7-watt)in the bathroom and it's very bright.
6. I also use one in the hall way in place of flood light. It works ok, the bulb is about standard size incandescent bulb. You may need an extension if you use it this way.
7. It's a bit expensive ...but if they last for 5 years, it would be a worthwhile investment :)
