I bought my lantern in 1996 and use it often. It still has the original bulb (my mini-maglite bulbs sometimes only last a few weeks) so either the bulbs are really good quality or the electronic module (which reduces the voltage to around 7.2volts) gives a really steady voltage. The lamp in this and the 15.6v lantern is 7.2v, 0.75amp. The beam of light is very focused and shines for well over 100 metres (330ft).
However I find the handle is almost useless. When the lantern is carried by the handle it seldom points where required. If I try tilting it, the spring loaded handle snaps around to the next position (especially with the newer heavier batteries - and Panasonic withdrew the lighter C battery earlier this year). Fortunately I have long fingers and can grip the unit around the battery, which enables me to direct the beam where I want it (and is also steadier than using the handle), but I wouldn't recommend the lantern to anyone whose hands aren't big enough to grip it in this way - make sure you try it before you buy it!
I replaced the rubber switch cap with a new one late last year (2001) after the original perished.

I have both (I think there are just two) flashlight/lantern attachments for Panasonic 12v batteries. I like the other one better than this.

I bought this one because I like the lantern style design. It is reasonably well built, and will cast a beam quite a distance. The problem is that the beam is quite narrow, and other than that beam, not much light gets spread around close by. I pointed it at a wall about 40-50' away, and the lighted area was probably less than 6' across. Since it is so narrow, the light it casts is quite bright in comparison.

I can't remember the model of the other, but it casts a wider beam, and illuminates the immediate area better. But the center spot is not as bright.

I'm kind of surprised that a $40+ flashlight attachment doesn't have any kind of adjustment ability to vary the spread of the beam. I'm considering trying to modify the reflector to do something like that.

Both lights have adjustable heads, so you can sit them on a surface and have the light pointed straight up, forward, or somewhere in between.

So if you're choosing between the two, this one is cooler looking, and will throw light farther. The other model is cheaper, and the light pattern makes it more functional for most uses.

If you have a Panasonic power drill, these make nice ways to use the battery, rather than let them sit unused, and die before their time. Also great to have around when the power goes out, which it does frequently where I live.

I bought this lantern to go with my 12v drill/driver that I have been using many years. Everything works fine, but the unit is much too bulky to include in my toolbox, so it gets left at home.

A well-made accessory for use with Panasonic battery packs. It could be improved by use of LED's instead of incandescent bulbs.

I am looking for search light to be used for Wild life Observation. I need info regarding the Wattage of the product and if possible , the field of lumination say at 100 feet.
