Black Diamond & Petal are two companies that make them. Not necessarily inexpensive but you get what you pay for. They have been very robust during my useage.

Thanks for posting this.
I looked at 2 items Black Diamond has 2 items under 30USD, so I looked at them. Many choices. https://www.blackdiamondequipment.com/en_US/spot-lite-200-headlamp-BD620662_cfg.html?dwvar_BD620662__cfg_color=Octane#details 3 yr guarantee Low 6 lm Not sure if that apples to both white and red. Petal (sic) had one that interested me, but for 60USD https://www.petzl.com/US/en/Sport/SPECIALIZED-headlamps/TACTIKKA-PLUSRGB 5 yr guarantee Low white 6 lm, RGB 2 lm Both posted low light level specs where I'd want them, meaning that I prolly will replace my aging Princeton and Petzl headlamps in the near future. I have also some other BC lamps, but not headlamps, and I agree that these have done me well. I won't give up my Chandler, and will likely update my keychain lamp for ~12USD. BioLite has some great products overall, but I don't think their head lamps compare well https://www.bioliteenergy.com/products/headlamp-330?variant=12623824289891# 1 year limited warranty Won't go as low as I'd like for low. 100 lm. So they are just not what I'd want for a night groove with my radio. But they are really well designed, and so are the other products.

Watching this thread with some interest, as I use my K3 to drive
transverters when roving in VHF contests, and it's hard to see the front panel controls at night. I tried making a light with a bit of aluminum angle stock and a short strip of white LEDs (the kind that come on a long roll), but even with a dimmer in line it was too bright. Maybe if I tried it with a short strip of red LEDs it would be better. Kinda reminds me of the red lights we used in the darkroom when developing film back in the day...

The lights in the C-130 on our nighttime airborne missions in SE Asia
were deep red to preserve our night vision, the trip to the jump target was in the dark. The effect of any light above the bottom end of the visual spectrum on night vision is dramatic. I'm a monochromat, I don't really know what "red" looks like to everyone else, and my dim light vision was really good, but anything higher in the spectrum killed mine just like all my troopers. The fact that I can adjust the LCD brightness on my K3 is really cool, I normally run LCD at 2 or 3. The one problem I have is I can't see the numbers on the keypad keys in any light. Fortunately, I know what the keypad looks like.

Maybe if I tried >it with a short strip of red LEDs it would be better. I'm active in ARES. My mobile radios are all Kenwood (that might change in the future if I go with KX2 for HF). Fortunately, all the front labels show up really well in red light. I use a really dim (dunno the lumens) light. I turn it on long enough to make changes to the radio, then turn it off. After reviewing recommendations here, I upgraded several of my lamps. "Low" power didn't mean really low in the past, and now I can get both low and red. Princeton, one of my favorites, used to provide lifetime warranties, but I believe that all their products are now 5 years. I think that generally quality everywhere has seriously declined. OOH, with products getting upgraded all the time, maybe we should not care for some products. OTO, I don't want to go to use something and have it fail unexpected. That's why I keep more copies of some kinds of gear. I can say that my older Princeton TEC head lamps are not showing any wear. Very solid, but bulky, I admit, design. Unfortunately, not red, not dim enough. They have a FRED model for 30USD that has pretty good reviews. Didn't mean to post an ad for Princeton...I think that there are many good products available today. The point is that I use red LEDs for a lot of night work, and wrt my radios, they all work well. I can't speak to many brands, however. But I suspect that they all use the same paint and display tech, so should all be fine. One point is that the kind of backlit LCD that can be turned off shows really well in red light, in my experience. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
