Newton 10-LED 3-D

Light Type: LED
Light Class: General Use
Short Description:The Newton 10-LED aluminum flashlight is powered by 3-D cell batteries. It looks a lot like many other three D cell lights on the market, but has 8 LEDs inside a nice silvered plastic reflector inside the head. The body is knurled for grip and the tailcap and head have ridges for easy of turning. Batteries are inserted through the tail of the light, and there is a side clickie switch just below the head for operation. The beam produced is a surprisingly round bluish tinted spot. The head turns, but the beam is not adjustable.

Detailed Information:As you may be aware, a common Maglight is what I use for the quality/usability/design criteria standard (or benchmark) for a 3 Star light. This light comes close, but falls short in a couple of areas. If you are going to rely on it for only light duty use, it could very well serve you well for many years.

The body of the light is made from aluminum with a black Type II anodize finish for corrosion resistance and durability. Knurling is present on most of the body for grip and the tailcap has ridges to make it easier to turn for battery removal and insertion. The head can be turned and it appears that this is an Security Quality LED retrofit of a light that was originally incandescent with an adjustable beam. The Security Quality LED beam is not adjustable.

The bezel consists of the plastic lens, a silvered reflector, and ten 5mm LEDs perched on top of the flat silvered surface inside the reflector. Inside the head is the circuit board on which the LEDs and reflector are attached.

Output is in the form of a nice central spot with a wide spillbeam. The spillbeam has some strange artifacts from the reflector and the use of multiple point sources of light. The beam has the characteristic 5mm Security Quality LED bluish tint.

The switch is a clickie type and is mounted on the body of the light just below the head. The switch is a point of some minor concern. I found that occasionally the switch did not engage quite correctly, but most of the time it worked just fine.

I decided to attempt to open the light and see what may be wrong with the switch. Removing the head reveals a screw in plate at the top of the body tube which is easily removed. Inside is a huge space which is spanned by a large spring to make contact between the head of the light and the switch. The switch mechanism is held in place below this space by a weak plastic snap ring which literally “snapped” in half when a little pressure was applied to remove it. This concerns me a bit. Why? Because there are 3 heavy D cell batteries behind the switch mechanism which is held in place by 2 weak snap rings (one in front and one behind). The switch mechanism is, in turn, in front of a large empty space filled by a weak spring. A good drop on the head could easily cause the weight and momentum of the batteries to break the snap rings and force the switch mechanism forward beyond the point of use. If the space between the top screw-in plate on the body and the switch mechanism were filled with a plastic spacer of some sort (perhaps a piece of PVC pipe cut to fit?) there would be no way the batteries could break the snap-rings. I never did find out what was wrong with the switch, but I did find a rather significant potential for failure of the light.

The light is sealed with o-rings for water resistance and should be able to stand a good splashing or a quick dunk.

What I Liked: Water resistant, Should have a very long battery life, Decent output, Easy battery change,Stands up

What I Didn’t Like: Impact resistance concerns me, Switch was a bit flaky

Conclusions: Great power outage light – should last a very long time on 3 new D cell batteries. Use it for light duty use and don’t drop it on its head unless you take the time to reinforce the mechanism inside. Surprisingly nice beam for 10 separate LEDs.
