Hello, I am just getting into the equipment purchasing phase of my GUE/DIR diving. I am looking to get into cave diving and will be taking Fundies soon. One piece of equipment where there seems to be a confusing amount of variation and differences is lighting. There are so many options surrounding lumens, lux, depth ratings, burn time, size, battery type, etc., etc. I've read the standards and understand the GUE requirements for backup lights (twist on/off, disposable batteries, bolt snap attachment) but there still seems to be a lot of offerings. A few I was looking at are:
UTD VIZ 10
Dive Rite BX-1
Light Monkey 3W
I know the Light Monkey (along with Halcyon, Heser, etc.) would be considered more traditional backups with 3 C's, but with all the advancements in more energy efficient LEDs over the last decade, it seems like other companies are capitalizing on this by making brighter lights with smaller form factors (the Dive Rite and UTD use 3 AAA's) while maintaining burn times. They are also quite a bit less expensive.
I would like some advice from experienced GUE/DIR/cave/tech divers as to whether these lights (or any others you would recommend) will fulfill my needs as I continue to get further into GUE/DIR and cave diving. In essence, what backup light would you recommend (may or may not be one I listed) and why? Also, are there any backup lights you would recommend avoiding and why (only of those that meet the GUE standards--e.g., don't tell me to avoid lights with magnetic switches or rechargeable batteries)?
