I went pass the aisle display for "special" items. There was a 15-flash light pack for less than $12, after tax. I passed the offer, because it listed the power output as a 18 lumens. How much power does it give out over a distance? LED works well in close distance, but it performs poorly in the outdoor.
The last LED I bought was a TechLite from Costco. It costs $20 for two, and now it sells for $18 for 3. The TechLite puts out 160 lumens - according the specification. It will take 8 of the "special" to give out the same lumens. Errr..
For $12 dollars?? I decided to give that a try..
I taped 3 of the units together to form a "18 LED" flash light. It takes 9 AAA battery, instead of just 3 AAA on the TechLite. I don't know whether the "special LED" unit will last longer than the TechLite, but I think it should. LED based flash light has very high degree of efficiency - the power is mostly converted into light. If the 3 units put out as much light as 1 unit, then the overall power consumption should be the same right??
By taping the 3 units as one, the LED provides a brighter, evenly distributed light, similar to the Krypton flash light - except at a different color temperature.
