Pocket Bright, Photon II, and CMG Infinity - 48hr Run

[**DONOTDELETE**]

Is it possible for lithium battery to have a "second wind" of power, like what they say in boxing, to have another spurt of power to continue the fight?

I do not know how to explain this but Photon's beam is down to the level of glimmer at the 6th hr. when it suddenly becomes bright again at the 25th hr. I'm sure no one touched those flashlights during the run.

Infinity (with regular Duracell battery) and Pocket Bright seem to be just coasting through the run but it is Infinity who's left with enough useable beam of light after 48 hours.

wow! can't expain that either but excellent post of the results!

Verge, interesting photo. Makes ya wonder if in the photons case this was a battery test or if overdriven designs aren't made for continuous on.

I checked out your other photos and the Streamlight Scorpion pic is great in how it let you see the useful light.

Objects in the beam like doors, straws, pencils, balls...really tell a lot about beam size, useable light, ability to tell color and such like.

Brock's figurine pics do this too.

If I had to guess, I'd say the connection inside the flashlight became bad (high resistance) and after some number of hours, restored itself. A minor vibration or bump to the table supporting the flashlights sometime during hour #24 might be all that was needed to get it glowing strongly again.

I'd try it again with a new set of batteries if you're so equipped.

Long run time is useless because AAs and AAAs can be bought in bulk for a real low price. There are rechargable AAs and AAAs too. Carrying around a dim led is useless. Also a waste of time and money to aquire a weak beam of light.

I'll take bright over total run time when the flashlight is powered by cheap readily available conventional alkalied batteries.

Excelent image! It tells the a great story. I am with Craig on why the Photon did that. I bet it had a bad connection, and somehow cured itself.

I will try taking a shot with the Arc and Photon and see if my Photon poops out the same way.

Just wondering, if connection inside the flashlight was bad shouldn't it have not glowed brightly and continously in the first place?

I tried including Arclight in this 48hr run but limited wall space and limited camera (Kodak DC290) lens width (widest is 38mm) prevented me from having 4 lightbeams side-by-side in one frame.

My other camera (Canon PowerShot A50) has wide lens (28mm) but it does not have the capability for time-lapse capture.

I'm waiting for my order of batteries to arrive, and in the next run as suggested by springnr, I'll place objects (10 ft. from flashlight) in the lightbeam for us to see useable light.
