1. Bathroom lighting (sticking out of the wall above the mirror) 4.5/5
I replaced all four of the 50 watt round incandescent bulbs that came with the house for this test. I was worried that the 180 degree luminance would be insufficient in this fixture (not lighting the wall enough), but it is surprisingly good. 3000K color is better than 2700K in my opinion; it gives a more natural appearance to my skin without coming close to appearing cold. It would be slightly better if these bulbs were omnidirectional, as you can see that the wall is slightly dimmer, but it still functions very well. Do note that they output twice as much light as a 50 watt incandescent; if you have a large number of low wattage bulbs in your scenario, this bulb may be too bright. So even though the bulb works by design in this situation, I'll be looking for one that's not as bright.
2. Kitchen: recessed down lighting 5/5
This is where the bulbs truly excel due to their 180 degree luminance. They're superbly bright and the color is again very pleasing. With these bulbs, I can provide my kitchen with higher quality light in a larger volume while using only 36 watts instead of 260.
3. Closet: non-recessed, frost globe pointing down from ceiling 5/5
This bulb works excellently here. The light shines strongly through the globe, just as the 65W incandescent that came before it in my house did. Toward the ceiling is slightly dimmer due to the 180 degree luminance, but it doesn't matter at all in this location.
4. Hallway: horizontal with respect to the ceiling, one bulb 3/5
These fixtures I have mount the bulb parallel to the ceiling. The result is that this bulb, not being omnidirectional, cannot light everything, so you end up with obvious shadows in certain parts of the hall. It's still usable, as the shadowing is strongest on the ceiling, and the light spreads to the floor better, but the effect is not ideal. Unfortunately, I'll have to find another bulb for this situation.
5. Bedroom: horizontal with respect to the ceiling, two bulbs in opposite directions 4/5
These fixtures are just like #4, but with two bulbs facing opposing directions. The bulbs work better here since you have two opposing directions of light adding up to basically 360 degrees. However, in my situation the bulbs' luminous areas don't cross, so you end up with lines of strong shadows on the ceiling. Not ideal, but it still works.
Overall, these bulbs have excellent light quality in most situations. They're a great value in lumens per dollar, and they have the lifetime warranty. Further, they have the highest efficiency I've yet seen in LEDs for my home: 100 lumens per watt (I've seen as low as a meager 45). If they'll work in your application, look no further!

Best Deals for G7 Power G7A21930 900 Lumen LED Light Bulb, 9-watt, Warm White
I purchased this bulb based on Prime availability and positive reviews.The light output is fantastic; Very bright and a nice color.
The metal heat collar acts as a heatsync, and gets too hot to touch. My infrared thermometer reads 115F.
My one complaint is this emits an audible buzzing. Using this in a swinging desk lamp, I can clearly hear a buzzing while sitting at my desk.
This product advertises itself as for desklamps, but if you have any average hearing you may notice a buzz. It is constant and can really grate on you.
Would not recommend for desk lamps. I will repurpose this to a ceiling light, but I am still disappointed.
Honest reviews on G7 Power G7A21930 900 Lumen LED Light Bulb, 9-watt, Warm White
Update 01/30/2013: re-upgraded back to 4 stars
G7 support was gracious to send me six new bulbs to replace the ones that buzzed (about a month after I contacted them last year). I apologize that I haven't had a chance to update this review, but I have since purchased more of their updated bulbs, and am happy to say that they have resolved the buzzing in the new bulbs. I have noticed that the newer bulbs are slightly more yellow in color than the original ones, but that is of minor consequence compared to the buzzing. Good customer service and product improvement.
Update 05/10/2012: downgraded from five stars to one star (LISTEN TO VIDEO)
Out of the seven bulbs that I've purchased, six of them have unbearably loud buzzingso loud that I replaced them with CFL's again. There was very slight buzzing when I first installed them, but they have gotten progressively louder over this past month. They've been put on our outdoor fixtures now, as they give me a headache indoors (not exaggerating). Turn up your audio and listen to the video to judge for yourselves. Contacted G7 support but no reply, and unfortunately past my return date. Waste of money for pricey bulbs that I can't actually use.. Purchase with caution, as these bulbs are advertised as 'No Buzz' on the packaging. False claims if some of them do in fact buzz. Read through the rest of the reviews, and you'll find that this is not an uncommon issue. Need some better quality control.
Original review 03/27/2012: five stars
These are instantly bright unlike our CFLs which take a while to warm up. CFL life span is also reduced with constant on/off activity, i.e. turning the lights on for only a little while, then turning them off (like our hallways lights). But LEDs do not suffer from that reduced life span when used for short periods of time throughout the day. So, this LED light removes those disadvantages, while saving even more electricity. Nice bright light (slightly brighter than our 15W CFLs), not too white, but just warm enough. Subjectively, I think the LED lighting looks better and more like natural sunlight than the off-yellow color from our CFLs. The only negative about these LED bulbs is the price.. but that price will come down the more that you purchase! Plus, no more mercury, and no more glass. These LED bulbs remove those safety hazards as well. Welcome to the future of lightingI'd buy these to replace all 40 of our CFLs in our recessed lights if I could afford to do so.. But for now, one at a time as the CFLs go out.

I wanted to try out an LED bulb, and chose this one based on price. I don't have any measurement equipment, but subjectively agree with Mike's earlier comments. It's a bright white light, certainly equivalent to a regular 75 watt bulb (maybe even 85?). I used it to replace a 75w CFL flood....the LED goes on immediately, gives more light, runs cooler, and doesn't have my CFL's yellowish tinge. It works in a dimmer set to near full on, but just binary (on/off). I'm not sure what a lifetime guarantee really means (practically speaking), but I bought two more of these bulbs anyway.
