Primary light is the one you generally use, and if the primary light fails during a dive, you switch to a backup light. What are the differences between them?

The primary dive lights should be:
  • They are robust and powerful.
  • They have long burn times.
  • They are higher in power, and brighter for deeper uses.

The secondary dive lights usually are:
  • They are more compact, smaller and lighter in weight.
  • They have shorter burn times.
  • They are typically less powerful, but sufficient enough to serve as a backup.

Carrying a backup light on your dive is a good idea. You never know when your primary dive light will die out, or if you are going on longer dives, it’s always worthwhile to have a secondary dive light with you for those deeper, darker depths you plan going through. For example, you can take D26 1600 as your primary dive light and D20 1000 as your secondary light.

Do you have any seconday dive lights?

I dive D26 1600 as a primary mounted to a goodman handle, and a D26 1100 clipped to my d ring.

The D20 1000 was not out, but I like the 26650 batteries for longer burn time.
