The latest version of the Black Diamond Spot headlamp is now available and generally at a price of around $40. Running on 3 AAA batteries (alkaline, lithium, or rechargeables) it has a max output of 75 lumen from the main led and is infinitely adjustable down to 4 lumen. At it's lowest setting runtime should be 200 hours or so. On high expect several hours before it starts to appreciably dim.
The main beam uses an optic rather than a reflector and provides a central hotspot gradually changing to spill. This focused hotspot is able to "throw" the main beam ahead while a secondary white led mode provides more even lighting for close up work. This mode too is able to be infinitely dimmed from 16 lumen down to 4 lumen. This eliminates the need to use a diffuser which in general is a rather inefficient way of handing that problem.
There is also a red led mode. This is useful to prevent ruining night vision or to prevent waking up tent mates when you go on your midnight stroll. Both the white and red led secondary modes have a strobe feature as well.
All features are controlled by one button on top of the unit. Pressing and immediately releasing will first turn on the primary white led. After turning the unit off the next time the button is pressed will result in the white led secondary mode being activated. Turning the unit off and quickly pressing the button several times will activate the white secondary led in strobe mode.
Holding the button down for 3 seconds will activate the red led (if previously in white led mode). The red led strobe is activated just as the white led was.
There is a battery indicator that is activated for a few seconds on power up. A green light indicates greater than 50% battery power. Orange means greater than 25% and red is for less than 25% battery power remaining.
The unit itself can ratchet down incrementally to adjust when the beam is pointing...from straight ahead to an angle that might be more appropriate while reading in your tent at night. The unit appears well made for a plastic headlamp, the light weight and straps seem quite comfortable. The central part of the hotspot in my unit has a yellowish cast to it with the rest of the beam being white. It's not a problem particularly and it's not noticeable outside but is somewhat noticeable inside. In secondary white mode (which would be used for reading) this doesn't apply at all.
One final feature of note is the lock out mode. This is to prevent the unit from accidentally being activated and the battery run down. To engage this mode from the off position requires pressing the button for 6 seconds. Blue leds blink momentarily to indicate lock out mode. To disengage lockout mode simply press the button again for 6 seconds.
The instructions aren't great particularly concerning replacing the batteries or rather taking the unit apart to replace the batteries. Turn the unit over and look for the arrow symbol. Rather than pressing down here or in the direction of the arrow you put your fingernail in at the tip of the arrow and pull back towards the front of the unit and the battery compartment will open up.
The user interface is well thought out, the output is bright, and the price is right!
