По умолчанию Spark SG3 & SG5 [XM-L2, 1x(R)CR123A, 1xAA] Review

Reviewer's note : Spark SG3 & SG5 were provided by Spark for review.

Spark has released the SG3 and SG5 headlamp powered by 1x(R)CR123A and 1xAA respectively.
.
.






My samples came in the cardboard packaging box with cut-out foam insert.
Note that the SG3 and SG5 have identical packaging. SG3 and SG5 come with headband, removable pocket clip, removable thread-on reflectored bezel, wrist strap, user manual. (The manual is available for download on Spark website.)
.
.

.

The SG3 & SG5 are quite small for their class. The hard(type III) anodizing is a matte gray natural and no flaws on my sample. However, anodizing doesn't seem thickly coated. Labels are minimal on the head, but clearly legible against the background. The carbon fiber sleeve is present over of the body. The light has no tail switch. There is knurling on the tailcap only. Fit and finish looks good.
.
.


The lights come with a removable pocket clip. It looks sturdy and hold onto the body securely. It's not reversible, allowing bezel-up only. The both clips on the lights are identical.
.
.


The light has 2 parts. The body is one piece with the head (i.e., the body has a built-in head). The pocket clip works as a good anti-roll device.
.
.






The Lights come in a choice of emitter types (Cool White or Neutral White), and my review sample is the XM-L2 Cool White.
The light has the non-reflectored bezel with the SCHOTT ultra clear lens which gives the poor flood beam. Note the bezel is removable and swappable (i.e., you can replace it with the reflectored bezel which gives both spot and spill beam). There's an electronic switch on the top of the head. Switch feel is similar to the Spark SL6S-740NW electronic switch. The switch has a good feel to touch and has short travel, which produces a clear soft clicking sound when pressed.
There is a flat positive contact point in the head, and the light has the reverse polarity protection function.
.
.




The reflectored bezel has a LOP reflector and is somewhat higher than the non-reflectored bezel in depth, due to the LOP reflector. But the diameter of the non-reflectored bezel is quite the same as the reflected bezel. The reflector is well polished with no noticeable finishing flaws and well-centered XM-L2 LED sits at the bottom of the reflector cup.
.
.






The above beamshots are on Turbo, High output on 1xSanyo CR123A, 1xEneloop AA, about 3 or 4 meter from a target. As you can see, the non-reflectored bezel is all flood.
.
.


The battery tube (i.e., body) is mostly covered in a thin carbon fiber sleeve. The sleeves on both SG3 and SG5 rotate easily. The wall thickness of the body is 2.44mm in the lights. The lights feel solid.
The SG3 runs on CR123A or RCR123A, and the SG5 runs on Alkarine or Ni-MH or Li-ion AA cell.
.
.


The screw threads are general triangular of good quality. Threads are well machined, and anodized which allow the light to be locked-out when the tailcap is slightly loosened. As supplied, threads are well lubricated. Screw threads action is smooth with no cross-threading or squeaking on my samples.
.
.


There is a gold-plated negative spring on the inside of the tailcap. The female threads are anodized too. The lights can tailstand, as the center of the tailcap base has a flat face.
.
.
User Interface

The SG3 user interface is the same as the SG5.
On-Off and mode control are controlled by the electronic switch. A quick press and release turns the lights on, and another quick press and release turns the lights off.
Holding down the switch will cycle between Low -> Med.1 -> Med.2 -> Max (i.e., High), in repeating sequence. To select your desired mode or output level, just simply release the switch. There is Super (i.e., Turbo), and this is accessed by double-clicking the switch in any mode. Note double quick click from Off will activate Super (Turbo) directly.

There is no flashing modes such as Strobe and SOS on the lights. The lights have mode memory, and remember the last output level used when you turn the light off and back on, even if you unscrew the tailcap. Note that the lights do not have mode memory on Super (Turbo).

If you hold the switch for around half a second before releasing, the lights turn on and shut off soon as if the lights show momentary light. This is an interesting function, but I don't know if this is the manufacturer's design-intended function.
.
.




The headband is good quality. There are stoppers for adjusting the headband.
.
.




The headband itself worked well in my testing. It is a single headband which is adjustable loop with two adjusters. I found the black rubber holder holds the SG3 firmly, but it doesn't do that for the SG5. Both SG3 & SG5 have the exactl same holder in size (i.e., inner diameter of the holder, holder space), but the two lights have the different holder space between the head-end and the clip-groove. It means the holder space doesn't fit in the head-end and the clip-groove on the SG5. The holder of the SG5 might fit in the head-end and the clip-groove as the holder is fairly flexible and stretchy. But it will loose the head-end and will not hold the body firmly, because the carbon fiber sleeve rotate easily.

It is good small size to hold and use. It can be used as an EDC light. Overall build quality is high.
.
.
Measured Dimensions

.
.
Standby Current Drain

Due to the electronic side switch interface, the SG3 and SG5 are drawing a small current when the light is fully connected. I measured this current as 116.2μA, 68.8μA with 1xCR123A, 1xEneloop AA respectively.
For SG3 and SG5, that would translates into around 1.4 years on 1400mAh CR123A, and about 3.3 years on 2000mAh Ni-MH respectively. This is negligible, not a concern. This current can be cut by simply unscrewing the tailcap a little when the light is not in use.
.
.
PWM

1. SG3

.
.
2. SG5


The lights show no sign of PWM at all output levels. I notice there is no buzzing sound at any levels.
.
.
Runtime

The runtime to fall to 10% of its initial output from 30 seconds after the point the light is first turned on (i.e., based on ANSI FL-1) for High is as follows :

1. SG3


1) Panasonic CR123A - Turbo (59min), High (91min)
2) AW RCR123A - Turbo (37min), High (75min)
.
.
2. SG5


1) Sanyo Eneloop AA - Turbo (52min), High (150min)
2) Duracell Ultra AA - Turbo (56min), High (88min)
3) AW 14500 - Turbo (39min), High (153min)

[New 13.09.14]
The lights have mode memory on both Ni-NH and Li-ion 14500, and this memory is retained even if you unscrew the tailcap (i.e., the lights recall the last used output after a battery change). But this memory effect is retained for about 10 minutes. (i.e., the memory lasts for 9~10 minutes after disconnecting the tailcap on both Ni-MH and Li-ion 14500. [New 13.09.14]
