I bought an LED flash light. It came with a red bulb for the night. I tried both on a pitchblack room, The night-bulb gave a red glow, but it was still a bit dark, when I used the LED bright light, it lit the whole room.

Why would I use the dim night-bulb to see in the dark, when the LED lights 10 times brighter? What is the night-bulb used for?

Thanks...

The bright white light afer you've used it for awhile will kind of leave you blind (you know, when you see spots) in the pitch black as your eyes adjust back to the darkness. But the red light is bright enough if your in the dark, your eyes can adjust much quicker after you turn it off.

Also if your camping in the pitch black getting one of those bright white LED lights in your face kinda sucks, use the red light and you won't blind your friends.

The last benefit of the red LED is that it much more Arnold "Terminator" like, you can reenact your favorite scene.

In the vietnam war, soldiers read maps at night with their army issued flashlight. The army flashlight had a red lense cap to give off enough light to read the map without diverting attention to their location. I have no idea why a regular light would have one. Maybe if you were developing photos in a "darkroom" and needed to look in a cabinet for supplies. LOL As for LED (light emmiting diode) , these led bulbs last almost forever without burning out. They are brighter and more energy efficient compared to standard bulbs.

Because of the way our eyes work, red lights don't make our eyes re-adjust to light the way white light does. This means you can use a dim red light and still be able to see well in the dark when you turn it off. Also, turning on a red light when your eyes are adjusted to the dark won't hurt and make you squint like when a white light gets turned on. I hope that made sense.

Sneaking around when you don't want any body to know your where you probably shouldn't be. It's great for finding your way to the refridegerator when you don't want to disturb anyone else.
