EDIT: I'm getting greedy, just pushed this to 375mA current, and got 201mW peak output after acrylic lens!
This build was a long time in the making, and cost a pretty penny. It took two diodes to get a working unit, but I'm quite pleased with the results!
Basic details:
- HL63133DG Opnext 637 nm "170mW" diode
- 1085 DIY Driver, powered by 2x 16340s
- Red Guidesman host with momentary cliky mod
- 340 mA Current Output (EDIT: Pushed to 375 mA)
- LPM of 179mW (EDIT: now at 201 mW) Optical Output using RED coated acrylic lens (from Qumefox)
My thoughts:
- Compared to every LOC build I've done (including a 330mW), this HL63133DG is clearly brighter. You don't have to struggle to see the difference, it's obvious and clear (would be to a layman off the street)
- It doesn't push red pointers into the realm of highly visible beams like a 445, or 532. In many situations, you still need to be on-axiz to see the beam. However, at night, or inside during the day, you can see the beam of the HL63133DG in a lot of situations where you just plain can't see a typical 660 LOC.
- The color is not substantially different than a LOC. You can tell them apart, but this is NOT orange. This is absolutely RED.
- I got the diode from Avnet. They charged $22 for shipping to Canada. However, it arrived in 1 day. It wasn't *quite* the overnight shipping they claimed, but I ordered it on the morning of a Wednesday, and it arrived on the morning of that Friday.
In the following photos, the 637nm is being compared to a 275mW LOC pointer:

This seller's reputation is unquestionably good (it's not a source on LPF but absolutely reputable), so I think the reality is that this diode was problematic, and they just didn't know. I'd like not to say any more on that point.
