Watching movies on a digital projector is a lot of fun. People have built their own movie theaters in their homes with these projectors, and their popularity is on the rise. Nothing can ruin movie night, though, quite like when the projector lamp goes out. While this can be a real hassle, you don't have to deal with it as often as you have been. There are things you can do to ensure a longer lifespan for your digital projector lamp so you can watch more movies and have more fun before you need a replacement.
An average household spends about 5% of its energy budget to lighting. Switching to energy-efficient lighting is one of the easiest ways to cut the energy bills.
If you are looking for a light to stow in your car or emergency kit, you will want a small light that still puts out a bright beam. LED flashlights are best for this application, hands down, and manual power lights are great for emergency kits as a backup for when batteries run out. Keep both kinds of light stocked so that you will have a stronger light if you need it. Use the manual light for brief uses, like checking on your child's skinned knee, and the battery powered light to scan for danger or signal for help.
