Everyone knows that light bulbs burn electricity, but if you get compact Energy Star fluorescent light bulb (which looks like a thick strand of spaghetti twisted in a circle), you can cut back on the amount of power consumed compared to an ordinary incandescent light bulb. In fact, if every American home replaced just one light bulb with an Energy Star fluorescent light bulb, that could save enough energy to light more than 3 million homes for an entire year, save up to $600 million dollars in energy costs, and prevent greenhouse gas emissions equivalent to 800,000 cars.

For yet one more way to cut back on your energy usage, consider getting the Crystal Energy Cell, which clamps on to a compact fluorescent light bulb.

The Crystal Energy Cell looks like a plastic dome, but is made from photo luminescence crystals. Turning on the light charges up the Crystal Energy Cell. When you turn the light off, the Crystal Energy Cell emits a soft green glow. Depending on how long you’ve left the light on, this green glow can last for several hours. While this light may not be strong enough to read by, it’s just enough light to let you see your way without stumbling through a pitch dark room.

Think of the Crystal Energy Cell like a nightlight that always turns on when you turn off the light. Attach this product to a light bulb in your bedroom and you’ll always see its green glow at night. Plug this product on a light bulb in a kitchen or hallway, and you’ll always have a light to see at night without turning on a light bulb and burning up electricity.

Since light bulbs eventually burn out, you can detach the Crystal Energy Cell from a burnt out bulb and snap it on a new one. Unfortunately, you can’t snap this item on an ordinary light bulb; you must always use a compact Energy Star fluorescent light bulb.

Since the Crystal Energy Cell is basically a glow-in-the-dark device, you may not want to place it on any light bulb where its glow might disturb you, such as on a lamp right next to your bed.

Overall, the Crystal Energy Cell is a unique idea that acts like a power-free nightlight that always turns on whenever you turn the lights off. As long as you use compact Energy Star fluorescent bulbs, you may find this product handy to keep you from bumping into anything in the dark.

Pros:

  • Power-free light source
  • Inexpensive
  • Always-on nightlight

Cons:

  • Only clamps on to compact Energy Star fluorescent light bulbs
  • May not want to use in rooms where you prefer total darkness, such as a bedroom
