Space light

[shiboleth]

Seeing as it's pretty dark in space, a flashlight (of sorts) would be pretty much essential.

Heres a list of features i think NASA might build into their lights.

LED (obviously),
Induction charging,
Indium sealed, Stainless Steel body,
Auto brightness (photo-diode instead of switch),
RGB output (enhanced color rendition)
Advanced Glass Mat cells (high safety, reliability)

OOO and lanyard

Or, like the cosmonauts, a beta-light, lol:laughing:

Any thoughts, im considering making this, seriously, hehe

Operating temperature range would have to be EXTREME if it's gonna be used outside the mother ship.

Actually though, it's not really all that dark in space...

you mean Advanced Glass Mat cells will work at temp around -300c???

btw, astronauts suites have built in lights,

NASA already got it covered.

Good point, I think AGM cells only work between the freezing and boiling points of H2SO4; way above -200*c.

Found this on wiki though:

'NiH2 rechargeable batteries possess good electrical properties which make them attractive for the energy storage of electrical energy in satellites[10]space probes'

Nickle Hydrogen it is then...

Have you any idea what Nasa are using at the moment?,because we always end up with it in the end down here on earth.

Well, if we are talking space probes, why not a nuclear battery? They work even better when it's cold. Of course, the shielding from the radiation adds to the weight. But then again, in microgravity, who cares :thumbsup:

Currently there are a lot of maglites up in space. the space station is running with what look like mag chargers, and quite a lot of images come back with mini mags being used. There was a thread about it some time ago... but basically, inside the ship/station... anything that makes light is good, simpler the better. Outside, well, it would be built into suits etc

i know for sure they use ultracaps for all there power storage needs. They are ultralight weight and charge the fastest under solar with special solar cells that are about 30+% efficiency. Batteries are obsolete in deep space as the temperature is just too cold for the chemistry.

Then again an ultracap D-cell in size is equal to a AA in capacity now and they have had these for the last ten years or so.

Im pretty sure they use photon lights a lot too but with lithium cells since they are lightweight as well and are not as temperature sensitive as alkys or Ni batteries.

I would like to see what they use in the suits as they have to run a long time while being somewhat lightweight and be bright as well. I know they use the ultracaps in the gov satellites.

Interesting thread by the way.lovecpf

 

[Dances with Flashlight]

Don't know about the features... but it will need a good name:

Forcelight; Vaderlight; Gagarilight; Vgerlight; L5light.

There have been prior post showing Maglites in various space vehicles.

Edit looks like Tolkaze beat me to it.

Yep, I noticed those while looking for photos of Casio G-Shock watches in space.

Thats a really nice beam pattern! :nana:

There is no diffuse lighting in space, so anything in shadow (ie half of everything) would be pitch black.
