Just picked up two of the Sylvania 14 watt, 1100 lumen LED bulbs, stated to be roughly equivalent to a 75 watt incandescent. Have them running in two lamps right now. Quick first impressions:
1) They run way cooler than the 100w bulbs that were in there, as my living room is no longer an instant oven
2) They are not quite as bright, since they are spec'ed at being roughly equivalent to a 75 watt incandescent, as opposed to the 100 watt incandescent bulbs they replaced
3) Color temperature, rated at 2700k, is very close to an incandescent...if you were not a flashoholic you would not notice the difference...and even then, unless someone told you to look, you probably would not notice the difference
4) When listening up close, there is a very noticeable hum, like listening to power lines...I am guessing it is the circuit that takes the 120v AC and makes it DC
5) The light is distributed very, very evenly! This is a major plus. I am very proud that LEDs have come this far and can drop right into common A19 sockets. Way to go Osram/Sylvania!
Model = LED14A19
Also known as Sylvania Model 78911
Power Draw = 14 watts
Apparent Incandescent Equivalent = 75 watts
Stated CRI = 80
Stated Color Temp = 2700K
Apparent Color Temp = Good
Actual Temperature (hand around bulb) = Very Good
Power Draw in Watts = Very Good
Uniform Light Distribution = Very Good
Mercury = No
Noticeable Hum = Bad
I probably would not use these if you are sensitive to low frequency hums, or in a bedside lamp. Other than that, I'd say these are pretty darn cool and a step in the right direction!
EDIT: I swapped the 100 watt bulb into a different lamp in the same room, and compared them. The 100 watt incandescent is noticeably brighter, but more than that, the 100 CRI is noticeable vs. the 80 CRI of the Osram. The LED bulbs appear yellower, while the 100 watt incandescent has better tint and a fuller palette of colors on the objects the light strikes. I'd love to see an 18 or 20 watt LED bulb equivalent to a 100 watt incandescent, with comparable lumens...soon, I suppose...as for the tint, we're close, but the CRI at 80 for the LED vs. 100 for the incandescent isn't quite there yet. But we are not far out...
