I recently picked up one of the Lowes Task Force 3 watt lights and thought I'd share my impression. I'm a newbie here. I stumbled across this web site about a month ago, got hooked, and ran out and got several 1 watt lights: Dorcy Meal Gear, Dorcy 3AAA Super 1-watt, Dorcy 3D 1 watt, and Lowes Task Force 3AAA 1 watt (the smaller cousin of the 3 watt).
The Task Force 3 watt looks pretty much exactly like the 1 watt version, just larger. It has a single power level when on (it would have been cool if it had a 50% setting). The switch is in the tail cap and is the reverse clicky type. It seems pretty solid and has o-rings to seal around the tail cap, bezel (that contains the collimator), and head (that contains the LED). The light feels good in the hand and has a rubberized grip so it won't slip easily out of your hand. When I remove the head and flip it over, I see a board with "LX-MS2203-A" printed on it. Not sure if anyone knows what this is (maybe a Luxeon part # for the driver?). There is quite a bit of room between this board and the Luxeon Star, but I don't know what's in there since I can't get to it.
The light is quite bright, brighter than any of my 3AAA 1 watt lights. It has a good white color (like my Task Force 1 watt). The beam consists of a bright, medium wide center spot surrounded by a fairly bright corona. Compared to my Dorcy 3D 1 watt, the Task Force has a wider, but dimmer center spot and a brighter corona. The Dorcy definitely has more throw, but the Task Force is probably a better flood type light due to the brighter corona.
I don't have a light meter so I can't provide any brightness numbers. But I used my DVM to measure some voltages and current during a 2 hour run. I used some slightly used Energizer 2C cells and measured the voltage of the batteries, voltage across the LED, and current.
Time__________Battery Voltage___LED Voltage____Current
0 (start)___________2.92V_________3.35V________1.00A
30 min_____________2.49V_________3.18V________1.00A
60 min_____________2.45V_________3.12V________0.94A
90 min_____________2.37V_________3.05V________0.72A
120 min (stop)______1.98V_________2.85V________0.20A
The entire light got slightly warm from the 30-90 min. marks. To my eyes, the light was at or near maximum brightness from 0 to around 90 min. At 120 min, the light was pretty dim, but still produced enough light to navigate around your home in a power outage. If I had used brand new cells, I think the light would have run a bit longer at near full brightness.
Anyone know if this is about how long other 3 watt 2C lights run? Also, since the LED voltage was higher than the battery voltage, does this mean there's some sort of boost circuit in there?
I like the light because of it's bright output and fairly small size (for a 2C light). But at $40, it isn't cheap. I feel it should sell for closer to $30 since it only has 1 power level. If I didn't already have my Dorcy 3D 1 watt, I wouldn't have a problem keeping this light. But I feel the Dorcy 3D is just as good (although quite a bit bigger) and for about half the price ($22 at Target). I'm thinking of returning the Task Force. Anyone have any suggestions?
I hope this information is useful to anyone considering the Task Force 3 watt.
