The key to the long life of any worthwhile piece of equipment is maintenance. With the advances in LED technology taking care of your LED dive light is now easier than ever. The equipment necessary is inexpensive and will ultimately prolong the life of your light which in turn will save you money. Aside from the light all you will need will be a couple cotton swabs, a small amount of rubbing alcohol, petroleum jelly or silicone grease and a clean- up cloth.
Step One – The first and most important step is to clear and area and set aside 30 minutes of uninterrupted time for the project. Nothing worse than to get distracted in the middle of cleaning your light only to return and find your dog has run off with some vital part of your disassembled light. The body of almost every flashlight is conveniently shaped like a bone. So if you haven’t completed “step one” you might just look in the garden for the missing flashlight body.
Step Two – Give your light a once over, test the switch, batteries, O-ring, and make sure the bezel or tail cap have a firm tight seal prior to disassembly. Knowing whether your light is functioning prior to taking it apart can save you much frustration upon reassembly.
Step Three – Disassembly. This is where advanced technology is your friend. In most modern led dive lights there are really a couple of parts depending on the make and manufacturer. The bezel, circuit, body, O-ring, batteries housing and or tail cap. Twist the bezel or tail off the body and remove the battery housing most Led flashlights are at this point disassembled. Please take time to note the direction of the battery housing for reassembly.
Step Four – Once disassembled break out the cotton swabs and rubbing alcohol. Dip a swab into the alcohol then gently clean off any residue and debris that may have accumulated on the bezel, circuit, battery housing, springs, body and tail cap if applicable. If the batteries show any cracks or corrosion make sure to replace them.
Step Five – Inspect the O-ring for pliability. A brittle O-ring will leak and destroy your torch. Once you are confident the O-Ring is in good condition wipe away any residue using your clean-up cloth and apply a thin coating of silicone grease or petroleum jelly to ensure a proper seal. After inserting your new batteries (keeping mind of direction) reassemble your dive light.
Step Six – Step six is often skipped over but is absolutely mandatory. Test your work… There is a nothing and I mean nothing worse than traveling to your dive location or worse getting in the water and realizing that not only does your light not work but is leak as well. Skipping this step can end your dive before it gets started as well as possibly incurring unnecessary expense.
I hope you find this article to be useful. As an avid diver I always use a check list for every part of my dive and have incorporated that routine into maintenance as well. Feel free to print this out and check off the steps as you complete them. Enjoy your life, invest in your equipment.
