More metal does not necessarily mean longer life but we see where the $2.50 bulb is shaving costs. $5 bulb on the right had 35.7g of metal.

$2.50 bulb on the left had a total of 23.4g of metal.

The ability to remove heat from the LEDs (or lack thereof) will affect the lifetime of the bulb. This is not just a drop in price, this is an all out price war between some heavy hitters. On a recent visit to the lighting aisle I was taken off guard when a pack of two 60W bulbs by Philips were selling for $5 ($2.50 each!). In this case, LED bulbs in my local Home Depot (Philips 60W) are hovering around $10. As with most all tech, I've watch the price drop over time. When I purchased my LED bulbs a few years ago they were around $15 a pop. I've switched almost all of the lights in our house over to LED in part because of the (small) energy savings, but mostly because I'm lazy: A 22-year lifetime means I don't have to climb a ladder for a while. This is capitalism at its finest! I find the battle of new tech, smart manufacturing, and massive demand intriguing. I spend way too much time in these aisles. You've probably noticed LED bulbs situated next to the incandescent and compact fluorescent (CFL) bulbs at your local hardware store.
