Philips' latest innovation: flatten the lightbulb

And the cost of the bulb is?
I wonder how the light spreads out when this bulb is in the centre of a room .
SBoverie must see the advantage of having this lamp fit an Edison socket. The answer is that more people will be likely to buy it if they don't have to replace their sockets as well.
Home Depot sells a pack of 4 Phillips 60-Watt incandescent bulbs for $1.50 with a total lifespan of the pack of 4000 hours. This LED bulb is rated at 25,000 hours or 6.25 times longer than the box of 4 incandescent bulbs, soooo.... I'm guessing that the LED bulbs will sell for $9.50 a piece.?
Not a bold design. The Edison base has been around over 100 years and has become the standard for incandescent lights. Heat is a normal by product of incandescence but it kills LEDs. Flattening the bulb shape to deal with heat is not a bold design.
LEDs run on low DC power 12 volts or less. Incandescence bulb run on AC power about 110 volts. The LED bulbs have to have a voltage converter to reduce the voltage. fluorescent fixtures, except for the CFL bulbs, have their own fixtures that work better than using the Edison base.
A bold design would be to make a new fixture standard for LEDs and skip being backwardly compatible with the Edison base. That is when the efficiency and expected long life of LEDs will come into play.
The "white" LED is the brilliant invention behind this. It's actually a fluorescent shell powered by an ultraviolet LED, which is even more efficient than the ionised gas that powers CFL bulbs.
It's one of the very few modern inventions so efficient that a biofueled human arm or leg could power it for hours by charging a battery.
I'm okay with it as long as I can still use a dimmer. LED are just too bright for me. The exterior wallpacks on a senser are great for security. I just wish the prices would come down a bit.
Not really "rethinking design" but design for lowest cost in spite of not meeting known EPA/DOE specification for 40/60W LED light bulbs. For example the known spec requires spherical uniformity of light intensity. The reality is people care more about price than light uniformity. Philips knows that and uses their market power to impose or eventually convince buyers to buy their flat bulbs.
