I'm actually stupidly excited about this.
It's a stormy night here, and dark as pitch. And as promised, here's some beam shots for your perusal.
The differences are
significantly more stark and obvious than any photo can convey. In person you can see the improvements instantly when switching between torches. Up close for general work it is a beautiful thing to behold. This is a game-changing modification for our inspection tasks, for sure.
All torches are 18650 bored, running charged batteries, and everything is normalised as much as possible. These are all dirty, beat up work torches, so the lenses were checked and cleaned as needed. All torches have the AVS flood lens fitted.
All images are taken with the DSLR on manual, exposure and white balance set and locked. Focal length 30mm. No post-processing enhancements etc. etc.
Approximate distances are:
- Light foreground grass patch ≈ 6m
- Sapling, right ≈ 6m
- Tall lighter grass, centre ≈ 10m
- Small bushy tree, centre ≈ 14m
- Tall dead tree, left ≈ 18m
- Distant shed, right ≈ 26m
In order, with "personal perspective" descriptions:
1. Elzetta Bones AVS "Gen 1" with flood lens. Good. 80-ish CRI, cool-ish tint.
1a. As above, but with the beam averted toward the distant shed.
2. Elzetta Bones AVS "Gen 2" with flood lens. Very poor. sub-70-ish CRI, bright blue tint. I hate it.
2a. As above, but with the beam averted toward the distant shed.
3. Elzetta Bravo AVS "Gen 1" with flood lens. Very good. 80+CRI, neutral tint.
3a. As above, but with the beam averted toward the distant shed.
4. Elzetta Bravo AVS "Gen 2" with flood lens. Average. 80-ish CRI, blue tint.
4a. As above, but with the beam averted toward the distant shed.
5. Elzetta Bravo AVS "Gen 2" with flood lens and Nichia 519a 4500K 95+CRI emitter and copper MPCB swap. - Unicorn excellent. Perfect colour rendering, perfectly neutral tint, slightly more "punch" in the beam due to the smaller emitter package size. Definitely slightly brighter, maybe around 10-15%, visually speaking, although it's hard to say how much is general (lumens) and how much is peak (candela) brightness.
5a. As above, but with the beam averted toward the distant shed.
Edit: I'm not a reviewer or anything, so I'm not set up to hand out numbers or even go white wall hunting. This is just my impression as someone who uses these torches enough to flatten a 3400mAh 18650 most days.
This is a massive improvement over the stock emitter, and I'm incredibly pleased with it. I'll be interested to see how it goes in the long run, and will try and remember to report back to this thread with an update in a few months' time on usability, battery performance, and any further thoughts or issues.
