Things to Consider When Shopping for a Backup Light

There are a lot of lights to choose from when you're shopping for a backup light. Here are some of the things to consider:

1. Size - Generally you would want a backup light that is small enough to fit into your BC Pocket so it's not just dangling around. Store it in a place that is easy to reach so if your primary light does go out you know where to reach for your backup light.

2. Burn Time - The burn time of the light should last 2-3 times your regular dive. There are lots of great choices out there for backup lights that will last you a couple of dives. Do try to get one that has no driver in the light, the driver will give your light a constant output and cut out as soon as the battery runs low. You would rather have one that will become dimmer as the battery runs low.

3. Ease of Operation - Make sure its' got a switch that is easy to turn on and off.

4. Type of battery - Most backup lights use AA, AAA, or lithium batteries. The cost of the AA or AAA batteries is generally much more affordable than the ones that uses lithium batteries.

5. Beam Pattern - The beam pattern should be focused for compact backup lights because it generally lacks the power that will allow you to see far enough when the light is spread wide.

6. Light output and color - Generally a backup light should be bright enough for you to read all of your gauges and allow you to get out of sticky situations. A while light is a plus because it allows other divers to see where you are much easier than if you were using a yellowish light.

7. Construction - The sturdier the better! Make sure the switches are made to last and the lights are well constructed. Try to avoid the old toggle switches that are very prone to flooding.

8. Depth Rating - Make sure it has the same depth rating as your primary light.

9. Always double check both your primary and backup light before your dive to make sure the batteries are still in good shape, especially if you're using rechargeable batteries that will self discharge over time.

10. Another alternative is to have a secondary dive light, which is a light that is strong enough to be a primary light but compact enough to be carried around without bothering you. See an article on a secondary dive light in our community.
