Detailed
Information:
The Nightstar CS is the little brother to the Nightstar. It has a smaller magnet and coil and as a result requires a little more shaking to charge the capacitor. The switch has changed to improve reliability and the addition of the tailcap for standing on end is most welcome.
Fit and finish are very good. It appears that the outer
body is molded as one piece. The internals are then
inserted from the bezel end and the lens is sealed with
adhesive, making the entire unit effectively one piece.
The switch is the only external piece added to the light.
It contains a magnet that activates a reed switch, thereby
operating the light without compromising the sealed
case. The tailcap cover will help protect the unit from
damaging drops.
The bezel contains the single 5mm StarCore LED, a reflector,
and a focusing lens which produces a medium spot of
light. In the head of the light you will also see the
capacitor which holds the charge generated by the magnet
and coil, as well as the magnetic reed switch.
The light produced by the NightStar is in the form
of a greenish tinted spot. In total darkness it provides
more than adequate light for safety and navigation.
As it starts to appear dim simply give it a few shakes
to brighten it up again. The interesting thing about
the NightStar relative to the other shakelights is that
the StarCore LED produces more of a greenish tinted
light as opposed to the common bluish tint of 5mm LEDs
found with the rest of the lights. The result is that
the NightStar LED is closer in color temperature to
the area where the human eye is more sensitive and it
gives better color rendition of red and orange objects.
Runtime Plot: Short runtime? Well, not too bad
for the small amount of electricity you generate by
shaking it back and forth. The NightStar CS takes about
twice as long to reach 50% as does the NightStar
RS, and it completely beats all the knock-off shakelights
I've runtime tested so far.
More
information on runtime plots is available HERE.
The switch is actually inside the sealed head of the light and it is activated by a rotating cylinder on the outside of the light. The little rotating cylinder, similar in size to the striker on a butane lighter, contains a magnet. When rotated it moves the magnet into position and closes the reed switch inside the head. The folks at AIT decided to go with a rotating switch to decrease the possibility of fouling which could render a sliding switch inoperable.
The unit is completely sealed and is rated watertight to a depth of 160 feet.
Ergonomics: Well, it's pretty much like any other flashlight. The narrow body inbetween the large head and tailcap make it less likely that it will slip out of the hand. The new switch design works very smoothly.
Batteries are never needed. Just shake back and forth
for about 2 minutes and you get about 20 minutes of
decreasing light over that time period.
What I Liked: Waterproof, Tough/impact
resistant, Never needs batteries Lightweight, Stands
up
What I Didn't Like: No regulation
/ Dims quickly
Conclusions: It takes longer to
charge up, but it is smaller and the magnetic field
is no where near as strong as the original Nightstar.
The chances of damaging magnetically sensitive materials
is therefore reduced, but the user should still be cautious.
I like this new version of the Nightstar!
As of January 2006 you can pick this light
up at your local Target store!
