Amber LED headlight?

[PhotonWrangler]

Would an amber LED headlamp serve the same purpose as a traditional yellow "bug light" in terms of being less visible to flying insects? I'm thinking of retrofitting a white LED headlamp with yellow or amber LEDs for working outdoors at night.

Pretty belated answer but yes.

I filter my 'white' LED headlights with yellow filter material (Rosco theatrical gel, most photography stores will know how to get it).

Problem replacing the LEDs is the voltage is different and you can burn out the amber ones.

Using a 3-AAA headlight with two batteries and a dummy cell and amber might work.

Or if anyone knows where to buy amber LED headlamps, say so please.

Some 5mm PT headlights are regulated, if it's current regulation amber LED should work.

Over here:

https://www.candlepowerforums.com/posts/2672682 WoodsWalker mentioned a while back that

" ... the regulated lights like the Apex, EOS and Quad are rated for lithium ..."

So I guess it ought to work on the LED side to allow swapping in an amber LED.

Worth a try

DINOTTE USA makes an amber light, that can be mounted on a head strap, or on a bike, or held in hand etc

Life time warranty, trade in (upgrade) option, and a ton of battery choices. http://www.dinottelighting.com/Photography.htm#

I just e-mailed Princeton Tec and asked if they could make the EOS with an amber Rebel, we'll see what they say.

If someone makes an amber headlight with the new Rebel Amber PC, would that be the best headlight for shoveling snow?

I don't know of any advantages an amber light would have over a white light. Anyone?

 

[MichaelW]

I should had added, shoveling while it is still snowing.

I was thinking of selective yellow or amber.

Doesn't attract bugs

Narrow emission rather than broad so less trouble to filter out for astronomy

Doesn't suppress melatonin -- won't interfere with sleep, useful for getting up in the middle of the night, or taking care of an older person or a baby with a disrupted sleep pattern;
cheaper and less dorky-looking than using these: http://www.lowbluelights.co.uk/products/index.html

Someone might want to try putting this 12v 3.5-watt bulb into a flashlight: http://www.axiomled.com/seaturtles/

I don't know what advantages amber would have over white for shoveling snow. Princeton Tec never did get back at me about an amber EOS.

A warm tint led would have advantages in while its snowing as there would be less glare from the falling snowflakes. Might be, that a yellow filter has the same effect.

Let is snow, let is snow, let it snow!

Heck it is hard to get a neutral-white in a headlight, so it might be damn near impossible to get a warm-white, 3000K CCT.

So for colored lights, what color would you pick? (page 12)

Myself, I'd rule out royal, blue, and cyan immediately.
Green, although it has the widest spectral distribution, it just doesn't feel like a good work light color. I'd pick it for the firefighter beacon color: red, red-orange, and amber look like fire!, and royal, blue, and cyan don't work with smoke.
Deep red is good for astronomy-protect the rods!, but down on lumens compared to red-orange, which has been done to death.
I like this yellow, it seems the closest to automotive selective yellow, for now.

but isn't up to modern brightness/efficiency standards.

[Direct] amber is the most temperature sensitive, so the cooler it is the more light you get (page 13), but that one advantage [for winter usage] over red-orange was not enough to overcome the lumen deficiency.

Now the phosphor converted amber has put some 'balls' into the light output.
and the SPD is MUCH wider than traditional amber (page 11) 80nm vs. 20nm.

So who will be the first to use the PC amber Rebel, a Zebralight H60 "A" perhaps?

 

[defloyd77]

Cree also has an amber XP-E, but I'm unsure of how it compares to the Rebel.

 

[MichaelW]

The xp-e is limited to 500mA, where the PC amber rebel can go to 700mA.

 

[defloyd77]

The xp-e is limited to 500mA, where the PC amber rebel can go to 700mA.

True. 51.7 lumens minimum at 350mA for the XP-E and 50 lumens minimum and 70 lumens typical at 350mA for the Rebel. Looks like a win for the Rebel.

I've got the same problem: the bug-zapper face syndrome. I simply put my mine away. Can't justify using a lamp I can't turn on for more than 2 minutes before darkness falls back on me in the form of flying bugs.

Filters seem to works great to keep bugs away. I've used red and green filters without a single bug approaching me. It seems to me it's a lot less trouble until someone comes out with an actual neutral colored headlamp.

 

[MichaelW]

Maybe soon my amber fantasy will be realized.

110 lumens looks good, until it overheats and the output drops by 50-75%

 

[defloyd77]

Whoa, that'd be one huge headlamp!
