Good zoomable light for its price – Flood-to-Throw Zooming 3W 80-Lumen LED Flashlight (1*AA) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
+ 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)
Cons:
- 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
Other:
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).
Bottomline:
Basic zoom lamp. Quite ok.
