Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week
+ As bright as Cree lamps in a same class
+ Compact size (length is 93 / 100 mm min./max. zoom)
+ Quite wide zoom range (see below)
+ Decent switch
+ Reasonable price
+ Uses 1xAA battery
+ No strobe or SOS modes
+ Has a real driver circuitry (which is visible inside)
+ Versatile lanyard
+ Tailstands (not very well when a key ring is installed but still)
- Moving part of the body feels loose. I doubt it is water resistant even it has o-rings on both threads. Looseness makes it feel cheap. Othe way machining looks ok.
Some minor things:
- No forward-clicky switch as in Romisen lamps
- Only works with AA batteries
- Single mode only - no "moon" mode with >10 hours of working time
I compared this "3W" flashlight to the other zoom torches I have bought from DX: C78 & RC-C6.
From a distance of 80 cm their spot's diameters are (in max./min. zoom position):
"3W" (this one): 7 / 70 cm
C78: 8 / 50 cm
RC-C6: 5 / 90 cm
So "3W" has bigger zoom range than C78 but smaller than what RC-C6 has.
I seemed to me that "3W" would give little more light than C78 or RC-C6 (latter uses a 3.7 V lithium cell). Differences are very hard to see with an eye so I adjusted their spots to a same size and used my lux meter. Max. value was:
"3W" (this one): 201 lux
C78: 122 lux
RC-C6: 184 lux
C78 has bluer tint than RC-C6 and "3W" has yellower.
Driver circuitry works down to 0.45 V taking 1.1 amps then. With 1.5 V it takes more than 2 amps (from my 2 A lab power supply).
