i would have given a LOT for a zebralight h501 19 years ago when i was a conscript in the local army. a couple of us were sent overseas as the advance party to prepare for an armoured exercise, as part of our duties (we were all armour signallers (usually APC mounted) cross trained to drive landrovers) we had to mount signal sets in the landrovers.
10 guys, 20 landrovers, pitch black, POS lights. The equipment was simply packed in plastic sheets secured with heavy staples and you guessed it right, staples would come loose from the store tent to the vehicle and handsets, nuts and bolts and other loose bits would tumble into the night (sloped ground), man, we musta lost a huge amount of stores that night. Some signal sets were only secured to the mounting boards in the back of the landrovers with 2 bolts instead of 4 and there were things missing too.
At that time, the creme de la creme of lights available in singapore was the 2xAA minimag incand, i had some plastic, white bodied, yellow headed everready 2xAA (parallel) which let me see maybe 5 feet and was NO HELP at all lookin for stuff on the ground.
Now, my brother in law when he has to go back for training for his reservist duty, returned my Ultrafire C3 (with 2xAA extension) telling me it was too bright and completely non tactical, he was spotted using it about a hundred metres away, and putting red cling film over it didnt help.
Gonna pass him an Akoray K106 if i ever get my orders in. (why the heck does it take KD TWO weeks to PACK? are they using fingerless elves to do the work or what?)
