There are pictures of the light on this site, go to the sticky at the top of this sub-forum and go to the volcano /Rainier and click on it. Overall length is 3-3/4 inches with a 1 inch diameter head and a 3/4 inch diameter body. With the CR123A lithium 3.0 volt battery this pocket rocket puts out more Lumens, about 110, which is more than almost all 2 X CR123A competitors. And with the RCR123A 3.7 volt Lithium-Ion battery nothing else can match it for the size and the price.
The Rainier @ $85.00 in HA or $95.00 in Stainless
110 Lumens with CR123A, run time 4 hours plus
350 Lumens with RCR123A rechargeable, run time 45 minutes
Competitors:
70 Lumen SF T1A Titan @ $239, run time 1 hour
120 Lumen SF L4 @ $175, uses 2 x CR123A batteries
80 Lumen SF E1B @ $149, run time 1.3 hours
350 Lumen SF M4 @ $ 349, run time 20 minutes with 4 x CR123A batteries
15 Lumen SF E1E @ $79, run time 90 minutes
130 Lumen (big bird) 7090 @ $199, run time 90 minutes
The Peak El Capitan with a single AA 14500 Lithium-Ion battery outputs about 140 Lumens for about 1 hour using the XP-G R5 LED. More power than all of the above except for the M4. With a standard L91 Lithium AA battery the output is about 70 plus lumens with double the run time of the SF T1A or the SF E1B. And at less than $50.00 it costs less than the SF E1E.
