Arc LSH
"Regulated" LED Flashlight
Available from & produced by: Arc Flashlight

The Arc LSH uses a High Dome Luxeon Star LED, other than that it is the same as the LS1 or LSL.
The LSH is current regulated so brightness remains near 100% until the batteries are depleted.
At that point the light goes into "moon-mode" and continues to produce light at a lower level.
The LS2 comes standard with the 123 size Tail Switch Pack.
 
 

This is the Arc LSH-P with optional 2AA Tail Switch Pack.
This option is great when combined with rechargable batteries,
eliminating the need to buy CR123 batteries.
 

The Arc LSH has various battery pack options. The "123" -cell size tail switch pack is the standard.
The "twist packs" (now discontiued in both 2AA and 123 size)
 
 

There is a limited run of Arc LSHF-P's from Arc that use the "Fraen Low Profile" optic.
This lens focuses the beam tighter, giving you more "punch" at the expense
of most of your side spill light.

Here are some comparison shots between the LSH-Standard and LSHF-P:
