G7 Power 40W Retro Light Bulb – LED lighting has never been so beautiful

The new A19 style bulb from G7 power may change the way you see LED lighting. No more big heat-sink fins, just a classic Edison bulb style without the power penalty.

With just 3.6 Watts, the bulb casts 400 Lumens, the same as a conventional (now phased out by law in the United States) 40W bulb. After some visual comparisons, I can’t see why anyone would need to use an old incandescent bulb (other than price). The bulb comes on instantly and glows with the familiar color that we’ve come to expect from incandescents. Its efficiency is amazing, at 138 Lumens per watt – more than twice as efficient as most compact fluorescent bulbs and greater than 10x more efficient than an incandescent.

A quick comment about cost. If the bulb gets high use, say 8 hours per day, it will consume just 10.51 kWh per year. Compare this with 116.80 kWh per year for the 40W bulb it replaces. At an electricity cost of $0.15/kWh, you save $15.94 in electricity per year – more than the $11.95 cost of the bulb. So this would be a great bulb for high-use fixtures around the house or places where the aesthetics and light quality are important.

Keep in mind that this bulb is NOT dimmable, so it’s not a complete replacement for the incandescent.
