Short Description:

The Elektro-Star headlamp is made by Elektrolumens. By adding a Luxeon I high-dome LED and the Elektrolumens 30mm optics to a waterproof headlamp, they have created a headlamp who's brightness rivals that of standard incandescent headlamps. This headlamp is intended for use in any situation (except diving) where you would need a very bright headlamp with good runtime.

The body of the headlamp is black plastic with yellow inserts on either side. The head is tilt-adjustable 90°, allowing the light to be directed where needed. The one side of the body unscrews to reveal the battery compartment. The 4 AA batteries need to be inserted with the correct polarity as listed in the picture below. The sticker inside the body of the light that appears to indicate battery polarity is not very clear. Inside the door are chrome colored springs which provide contact. At the other end, 4 brass contacts provide the electrical connection. When replacing the battery compartment door it is necessary to align the 2 slots in the door with the two tabs between the batteries. The compartment is sealed with an O-ring which was dry in the unit tested and should be lubricated with a silicone grease periodically. On the other side of the body is the switch which is twisted in one direction for on, the other for off. The switch clicks in place.

There is a 2 point elastic headband attached to either side of the light body which is adjustable. There is also a rubber foam headpad attached to the back of the light for comfort when worn.

The bezel contains the Luxeon I high dome LED mounted on an aluminum heatsink, 30mm collimator optics, and a smooth reflector which fits against the backside of the collimator lens. The reflector is for aesthetic purposes only, giving a clean, finished appearance to the bezel. All of the light is collected and projected by the collimator lens alone. The bezel is also sealed with an O-ring and should never need to be opened as the LED should never burn out.

The beam is a bright, tight spot. The spot is off-center in a diamond shaped corona, very similar to the Blaster 2. This is an effect of the optics and has little noticeable impact in practical use. Battery life is expected to be 10-12 hours, dimming over that period of time.

Reviewer's Impressions:

Although not as bright as the Blaster II, the Elektro-Star is a fine implementation of the Elektrolumens custom optics and Luxeon Star combination in what would otherwise be a very plain incandescent headlamp. The work is obviously a retrofit of an existing headlamp to carry the Elektrolumens elements, but the retrofit work is very well done, far surpassing the original quality of the headlamp.

Fit and finish of the headlamp itself is OK, but not great. There is obvious misalignment of some parts, but none too severe. The headband is not that well made, but will suffice for normal use. Inside, Elektrolumens has done an excellent job of adding the Luxeon Star and 30mm optics, leaving the original reflector (now drilled out to fit the new optics) in place to give the unit a more "finished" appearance.

I'm a little unsure about the durability of the headlamp. In appearance it seems pretty tough, and with the addition of the Luxeon Star, the user will never have to worry about a blown bulb. The switch concerns me a little bit since it is a bit loose, and it appears that debris or water could get into the mechanism. I could not get inside it to inspect the quality of the switch and its seals.

Output is very good, having a central hot spot that rates about 1/2 of the brightness of the Blaster 2 with similar optics. This is the result of using AA batteries as opposed to the more powerful D cell batteries used in the Blaster 2.

Beam quality is good with a central hotspot off center in a diamond shaped corona. This is the normal appearance of the beam from the 30mm optics and has almost no effect on usability. You will notice the difference in the color of the light between the Elektro-star and the Blaster 2 in the beam pictures above. This is the result of natural variations in the production of the Luxeon Star LEDs and the color tint is really not noticeable at all in practical use. Rarely do you shine a light on a flat white surface just to see what the beam looks like. Usually you are looking at whatever you are illuminating. The Luxeon Stars do seem to give a little better color rendition in my opinion, than the clusters of bluish tinted 5mm LEDs that you usually see in LED lights. This is especially noticeable when looking at red colored objects.

The unit is stated to be waterproof, but without a depth rating, so I would call it "dunkable". It should be able to withstand rain and splashing. If it gets dropped in the lake, shake it off, inspect it for leakage, dry it out if necessary (it shouldn't be) and continue using it.

Important things to note: The light is a bit heavy since you have 4 AA batteries hanging on the front of your forehead. At least you don't have wires running around the circumference of your head to a rear battery pack that could get caught on branches, etc, however it does feel a bit off balance.

Improvements: I think Elektrolumens has already done an admirable job of "improving" what appears to have been a standard incandescent headlamp prior to retrofit with the Luxeon element and optics. A third strap over the top of the head would have been welcome in assisting retention of the headlamp due to its weight, but the headlamp was only designed for a 2 point strap system.

+ + + Pluses: Watertight, Impact resistant, Long battery life, Bright, Easy battery change

- - - Minuses: Heavy / off balance, 2 point strap only, Battery polarity not labeled correctly in light
