There are various types of functional Class IIIa Green Laser Pointer you can select from. The Ultra fire WF- 501B laser pointers are some of the most popular type. They have been produced using the latest and most advanced technology. This has resulted to its high performance and effectiveness.
Some of the unique features linked to these types of laser pointers include the fact that it has been made with one of the best type of material. This is the aluminum alloy material. This material is known for its strong nature thereby making anything including the Laser Pointer Green 1000mw produced by this material to be quite durable. It can last for a very long time regardless of how often you use your laser pointers.
Most 50mw Green Laser Pointer Pen have in the past used Automatic Current Control (ACC) - a constant current driver. The result is generally fluctuations in output power as the pointer heats up. These may be quite large and result in either a very dim spot or an excessive and illegal super bright beam. The trend now is to use an APC driver to eliminate variability and also make it harder to "boost" the output to an illegal and dangerous power level.
Life expectancy and warranty: Sometimes there will be a spec like "2,000 hour lifetime". This is probably mostly relevant for the expensive green laser pointers and may be reasonable. Certainly, anything over 1,000 hours is adequate for a pointer used as a Laser Sights for Handguns within one's (human) lifetime (or until it becomes obsolete). However, any lifetime claim isn't of much value unless there is an enforceable warranty!
The shape and size of a pointer is determined largely by the type of battery used. The tiniest red pointers use button cells like the one shown in Components of Simplest Red Laser Pointer. Long thin pointers (red or green) use a pair of AAA Alkaline cells like the one shown in Components of Typical Green Laser Pointer. The fat squat type shown in Components of Edmunds Scientific L54-101 Green Laser Pointer uses a CR2 lithium cell. Whether aesthetics determines the battery design choice or vice-versa is anyone's guess.
