New Light Bulb

There was only one kind of light bulb available at our local grocery store today. This kind. It's more efficient than the old ones. It was more expensive, but it should last longer. The old light bulb is near the bottom of the photo. The new one is more opaque. You can't see through it.

Unless you hold it up against the light. This bulb is much heavier than the old ones.

The old light bulb is on the right. You can see the filament at its base.
