Spark SX5 with separate battery pack and multiple battery configurations
4x18650 won't give you enough run-time for caving? -
Armytek wizard.....vs zebra h600
Re: Armytek wizard I completely disagree. When indoors, I frequently use my headlamps pointed straight up at the ceiling, to bounce the light and illuminate the whole room. The switch placement on the Wizard would place the switch against my forehead, making that usage pattern extremely... -
ZebraLight H502 XM-L
Hard to say. Their product cycle typically seems to be in the 12 - 24 month range, longer for some models, shorter for others, depending on how successful it is. The SC600 has been out for almost two years now, and they don't seem to be considering retiring it; they're updating it in fact. On... -
ZebraLight H502 XM-L
They have the C model already, which is a fairly warm tint. I don't see why they'd do an additional neutral model as well. If you want a warm tinted 502, go with the C. -
Searching for very low brightness, red LED headlamp for astronomy
Yeah, this issue of the spectral purity of a stimulus is a big issue in this kind of work. My experience with it has been that colleagues I've known who've worked specifically with color perception and its neurophysiological underpinnings go to great lengths to acquire light sources that are as... -
Searching for very low brightness, red LED headlamp for astronomy
Semi, I don't think I am missing the point you're making, I think you're missing mine. I don't have time to give an in-depth response to your latest post because I am going out of town for the next five days on a camping trip with my wife and kids, so a more thorough response will have to wait... -
Searching for very low brightness, red LED headlamp for astronomy
SM; I'm going to delete the portions of your post that aren't directly relevant to the comments I'll make, or that I agree with and/or think I've already stated clearly, and/or the things you state that are in agreement with what I've already posted. The problem here is that this occurs only... -
Searching for very low brightness, red LED headlamp for astronomy
I've run into issues with people some times because of this. They object to my use of my NVG lights (I typically use a pair of Covert Photon Micros, one on my cap and the other on a neck cord), instead of a traditional red light. After a while, I got tired of explaining it to them, and simply... -
Searching for very low brightness, red LED headlamp for astronomy
That is one reason that I know of. I'm also of the understanding that deep red night vision lights can produce quite a bright signature on IR scanning/detection equipment, making it quite easy to find people/vehicles using them as a result. The 505 nm NV lights don't have that same problem. -
Searching for very low brightness, red LED headlamp for astronomy
I disagree that deep red is best for reading under low light conditions. In order to activate the cones the light intensity needs to be at the mesopic level, the intensity level that's at the boundary of the photopic/scotopic transition. A night-vision green light, with a wavelength of about... -
Searching for very low brightness, red LED headlamp for astronomy
Glad to help guys. I don't normally announce my credentials on internet forums, but I hold a PhD in experimental cognitive psychology, am a college professor, and I teach classes in visual neurophysiology, sensory perception, physiological psychology, and so on as part of my job. I've also... -
A headlamp with few specific demands for a world downfall.
For 1) I'd go with the H51Fw. I have both the 51Fw and 502d and I prefer the Fw, as I find the beam more useable. The 502d creates a lot of glare in my glasses and if I angle it up to avoid that, it can be bothersome to others around me. That said, if you don't wear glasses, then the 502d... -
Long-life lantern/flashlight for railroad use.
Check out the Favourlight lanterns. A quick Google search will get you their webpage, and then just go to their Products link at the top of the page. They make a 6xD cell lantern that's supposed to be very good. It's the same as the big one Eureka makes. They also make several smaller ones...- B0wz3r

Does 4xAA or 6xAA Neutral (or Hi CRI) Exist?
B, check out Dereelight's Javelin. It's a P60 host that holds 2xAA and has an extender for 3xAA. With the extender and a trio of L91's, it's right in the voltage range of most of Nailbender's drop-ins. He's got a new HCRI XML available now too that should work in a Javelin.- B0wz3r

ZebraLight H502 XM-L
I came up with an easy way to solve the problem, but I don't have a pic and it's not easy to describe. I may have posted about it in the Zebralight Mods thread here, but I don't remember for certain. Check there to see.
