LD10 In Turbo Mode:
Again the pictures don't show very well - but the general mode of the TK10 is about as bright as the Turbo Mode on the LD10 and the TK10's turbo mode is nearly twice as bright as the Turbo mode on the LD10.
Use of the Diffuser:
One thing I really liked was that you could add a diffuser to this light. It made reading very easy. I used it to read multiple nights in bed - and when I remembered I could set it flat on the bottom bezel - it sat up like a candle and was plenty bright for reading and map use.
One should use the diffuser in the 9 lumens general mode as that is plenty bright for reading and allows the battery to survive the longest.
Case:
The case was made of cordura and very tough. It had a D ring to be hung from a small 'beener or your neck if needed. It had a velcro back that allowed you to hook it to your belt without taking your belt off - and another loop to allow you to loop it on your belt more permanently.
Odds and Ends:
The flashlight also comes with a lanyard, extra o-rings, and an extra button boot in case you rip the old one One note - you will need a pair of Cir clip Pliers to replace the button.
SOS Mode:
The SOS mode was really cool. When you 1/2 click the button four times (in general mode - from the off position) it blinks three times rapidly to tell you what mode it is in. Then it blinks 1,2,3 times then pauses for two full seconds. I really like this option - although - in testing it - it made me a bit sick. You don't want to look directly into the light.
Strobe Mode: If you turn the bezel to Turbo Mode and then 1/2 click the button it goes into strobe mode. This will likely send a person with epileptic person into a seizure if they are succeptable - be careful. However, this mode is guaranteed to get attention. It is super bright and super annoying!
General Impressions:
For the price - about 50 dollars - this would be a great backpacking flashlight or a smaller PSK flashlight. It is made for survival situations and I really enjoyed using it.
