MityLite Submersible Flashlight
This durable flashlight is virtually unbreakable, and is powerful enough to be seen through water, smoke, fog and rain.
Initially, I wondered why he would make such a purchase, but after using this light in the evenings when it is raining, I can see the benefit of owning a submersible flashlight.
Product Description
The MityLite® Submersible Flashlight is small, it measures a mere 4 3/4" in length. Ours is black, and has the MityLite written in white letters on the side, with the word submersible in tiny black letters. (The newer versions don't say "submersible" like our older model does).
This product is made by Pelican, and features a body made of polycarbonate resin that is virtually unbreakable. The MityLite® Submersible flashlight has a lamp module that consists of a Laser Spot Xenon®, which allows the light to be seen through water, fog, rain and even smoke.
The end of the flashlight has a long 1 3/4" clip that allows the user to clip it onto a shirt or pants pocket, backpack, purse, camera bag, etc.
The MityLite® is compact, lightweight and equipped with a shirt clip, making it easy to fit into pockets, purses, tool kits, or other such item. The tip of the flashlight is covered with a 1 1/4" long clear plastic to protect it.
Turning the MityLite® on and off is simple, you only have to turn the clear plastic cover clockwise, and the bright light will illuminate. To turn off, simply turn counter clockwise - this feature assures you that the light won't be turned on by accident, and wear out the bulb and batteries.
The side of my MityLite® Submersible Flashlight reads that it is approved for use in hazardous locations with Eveready #E92 alkaline batteries and lamp CAT #1904 only. It is ATEX, FM, CSA and AUS approved and water resistant. however it is not applicable for diving situations.

My Experience
I have not had a chance to use my MityLite® Submersible Flashlight under water, but I have used it outdoors in rainy weather and when it's a tad bit foggy outside. Winters in Alaska are long and dark, and it's important to have a flashlight that allows one to be seen when they are walking along the roadside in the morning or evening hours in inclement weather.
This flashlight fits the bill, and I find that, for me, it is even quite visible when it is snowing outside, and since it's a submersible light, I don't have to worry about it being damaged by weather.
For it's size, the MityLite® Submersible Flashlight is incredibly bright, and beats other flashlights of the same size, in my honest opinion. I love the small size, this tiny light really packs a punch yet fits easily into a car glove box, a purse, or even a shirt pocket. It really comes in handy when we have a power outage, and we do have them numerous times every winter.
The Pelican MityLite® Submersible Flashlight retails for $16.00, which I feel is a very fair price for the quality. I have certainly paid higher prices for flashlights that didn't perform nearly as well. This flashlight has been dropped and has not sustained any damage, it truly is well made and extremely durable. This product gets two thumbs up.
