Lumapower TRUST Series Model 1 review
It's been a while since Lumapower last debuted a single AA light: The ConneXion x2 (reviewed early 2009!). I'm glad to introduce Lumapower's latest line: the TRUST Series, starting with the first model (aptly named "Model 1") a solid new entry into the single AA realm. This is a solid, functional light, designed for practical use in most EDC (every day carry) situations.
This is the first of this new line, with an 18650 powered light (Model 2) to follow, as well as other battery types.
It can run effectively on AA cells (Nimh, Lithium, or, in a pinch, alkalines) but achieves highest performance when used with rechargeable Lithium ion (hereafter referred to as Li-on) cells (14500).
Ricky at Lumapower sent me a review sample of this latest release. I'll do a thorough examination and put it through its paces.
Specs and Information
The Model 1 is a multi-mode AA/14500 cell light that has four levels; these are selected by the forward clicky. It features Lumapower's latest user interface, an enhanced version of the usual "Smart UI" that will be described below.
The specifications (as quoted from Lumapower) are as follows:
Standard LED: Cree XP-G, R5 flux, WB tint
The Model 1 is optimized for Li-on use and achieves highest output using 14500 cells (200+ lumens). Using regular AA batteries (1.2-1.5V), one gets 90+ lumens max output. Note, all lumen numbers are OTF estimates (out the front).
Runtime (provided by Lumapower):
On Max: 47 minutes, on high: 2.7 hours, on medium: no data, on low: no data (14500)
On Max: 70 minutes, on high: 4 hours, on medium: no data, on low: 21 hours (2600 mAh nimh)
- 4 output levels (no SOS/Strobe, low-medium-high mode sequence when bezel
loosened, max when bezel tightened)
- light mode memory lock (Smart UI) available on bezel loosened mode
- Deep carry, reversible clip with retaining ring
- Forward clicky with momentary-on. Tailcap lockout available.
- Square threads
- Double side AR-coated lens
- Orange-Peel textured reflector
- Tail-stand capable
- Double spring system for enhanced battery stability and contact
- Type III Hard Anodized (Grey) aluminum
Standard Dimensions:
- Overall length : 101mm
- Body Diameter: 21mm
Modes available:
Max 200+ lumens (14500), 90+ lumens (nimh)
High 80 lumens (14500), 60 lumens (nimh)
Medium: 30 lumens (14500), 20 lumens (nimh)
Low: 8 lumens (14500), 5 lumens (nimh)
The included accessory kit is sparse, a bit of a change from the usual Lumapower offerings. It consists of a couple extra o-rings (black).
I'm surprised by the lack of extras. No spare switch boot or lanyard?
Retail price for the Model 1 is about $60
First Impression: Versatile and Powerful
The Model 1 is nicely constructed with an attractive dark gray hard-anodized finish. The parts are well matched and the finish is well done with few flaws. The square threading is thick and robust however the parts on my sample had quite a bit of thread slop. This was reported to Lumapower so later production models should have this play fixed.
Knurling is found on the head and tail of the light, much like many of Lumapower's other offerings. I did find the knurling to be reasonably grippy but would have preferred a somewhat more aggressive cut for better handling. The Model 1 has a smooth centre section with no knurling or flats.
The biggest change (and improvement) over previous offerings is the nice, deep-carry, reversible clip. This clip is attached to the light using spring pressure and is locked in place using a retaining ring. The ring is fairly effective but must be firmly tightened or the clip can rotate or fall off. The overall design is good, but I think the retaining ring should overlap the clip to provide a more secure fit. The body is reversible so the light can be carried bezel down or bezel up (for clipping to a cap for hands-free use for instance).
Both the head and the tail of the light use springs for battery contact, so consistent contact will be maintained at all times. I found this to be a nice touch but likely contributed a bit of extra length to the light. An interesting note is that AAA batteries also function in this light! This may be useful in some emergency situations, when no other cells are available.
The glow in the dark bezel o-ring and tailcap button are nice touches, and max output is very impressive on 14500 cells. Using Nimh cells, max is output is still respectable.
Battery availability and compatibilty
The Model 1 is compatible with normal AA cells, but provides much more output using rechargeable Li-on batteries due to the higher nominal voltage of these cells (approximately 3.7V). Rechargeable Li-on cells are commonly referred to 14500 cells. AA batteries are the most common battery on the planet, so cell availability should rarely be an issue.
Good interface: Smart UI for single, dual or multiple modes
The Model 1 uses an enhanced version of the now-standard Lumapower UI, named Smart UI (first released in the Tool Series Mentor light).
When the head of the light is tightened, the light only offers max mode (200+ or 90+ lumens depending on battery type). The light now can be used for tactical strobing, signaling etc. using the forward clicky. Simple and effective.
When the head is loosened, the Smart UI is available. The Smart UI offers the typical three mode interface (low-medium-high brightness sequence with memory mode) but also offers the ability to lock-in any single brightness setting.
Here's how it works: the light must be on for at least 1 second or more to set the mode memory. At this stage, turn off the light and quickly pulse the light on 4 times (within 1 second). Now the light is locked into that brightness setting and works like a single mode, forward clicky light.
To unlock the light, simply pulse the light on 4 times within a second. The light is now back to the standard 3-level interface.
There are no strobe or SOS modes, so the interface remains relatively clean, and simple
Locking the mode is a bit fiddly initially, but once learned it's easy to change from multi-level to single level interface. Adding some kind of mode-locked indication would be helpful. In any case the Smart UI should satisfy many different types of users.
The Model 1 allows one to customize the UI; it can be used as a four mode light (with memory), a two mode light (using head twisting to change modes), or simply locked into one, bright mode.
I did have issues with thread slop on my sample though. The loose threads allowed the light to fluctuate between max and other modes if the light head was rocked or pressed. Unscrewing the head more than half a turn can prevent this.
Useful, Well spaced levels
I found the range of levels on the Model 1 to be well spaced for most use. Note that I will be stating a range of values for each mode as the output varies depending on battery type.
The light has a good low mode (about 5-7 lumens) that is quite useful and gives a nice extended runtime of around 20+ hours. This is a good general purpose level but an even lower low would be useful to maintain dark-adapted vision.
Medium level is about 20-30 lumens, a balance of power and runtime. This level is great for most normal use.
High is a decent 50-80 lumens. It provides a bit more punch than medium while still providing reasonable runtime (2.5 – 4 hours).
The maximum level (90-200 lumens) is impressive. This will please those looking for maximum output at all costs. It is, however, not well regulated with 14500 cells, with a steady declining output on max. All other levels (and cell types) are well regulated. The light got warm but did not overheat on max output.
PWM (pulse width modulation) is used for dimming the light. The measured frequency (as provided by Lumapower) was around 1.3 Khz. I did not detect any PWM flicker in use, though it can be observed by shaking the light quickly.
Size, ergonomics
The Model 1 is a medium sized AA light that fits well in the hand. It is slightly longer than most popular offerings due to the extra length of a forward clicky (102 x 21mm).
The ergonomics could be improved somewhat by making the knurling more aggressive and/or adding some knurling to the centre section of the light, however it does work well in the current configuration.
The recessed tailcap button works well when used in a cigar or overhand grip and provides a solid feel with good feedback before latching on. The scallops in the tailcap allow good thumb access while still providing reasonable tailstanding.
The clip is firm, but does not provide enough grip at times because the smooth centre section does not provide enough traction on most fabric surfaces. More knurling or texturing would solve this issue. I am glad to see that the clip allows deep carry and does not interfere with mode selection, battery changes, or head twisting.
Beam, tint quality
The Model 1 uses the Cree XP-G LED (R5 flux) for max output and a smooth beam. My sample has a WB tint cool white emitter. The tint is quite cold, with some hints of blue at times. While the output is stark and impressive, it is too cold for my tastes.
The Model 1 uses a textured reflector that provides a useful, broad spot with a somewhat ringy beam. This is somewhat odd since the XP-G LED tends to provide a smooth beam in most reflectors. I suspect that the large opening in the reflector and the recessed location of the LED may be leading to some rings around the corona of the beam.
Nonetheless, the effect is quite subtle and not noticeable in normal use. The broad spot and smooth transition to the bright corona are ideal for short and medium range use. This light is not a thrower by any means, but the beam pattern is well suited to an EDC (every day carry) type light.
The emitter was well centered, using Lumapower's proprietary LED centering system.
Upgradabilty, other Notes
For those who like to tinker, the Model 1 is not glued or potted, so there is easy access to the LED, though I have not tried to access the driver. In fact, my review sample has already undergone an emitter swap to a neutral tint LED. I am hoping that Lumapower plans a neutral run at some point as I find that tint much more pleasant and easy on the eyes.
The tailcap switch module has been changed to a sealed unit for more consistent construction and activation. The body threads are anodized and the switch unit has insulated threads, allowing for tailcap lockout when slightly unscrewed. This will prevent accidental activation.
The overall size of the light and the multi-voltage circuit would lend itself to other battery configurations. A CR123 or 2AA tube could be a nice option if Lumapower decides to pursue this path. This would allow for many different "lego" options.
Summary
Lumapower has made an excellent introduction to the new TRUST Series with the AA powered Model 1 light. It is a solid, mid-sized, versatile light that offers four well-spaced levels with no extraneous blinking modes. One can achieve a blinding 200+ lumens while still retaining a long-running low mode.
The Model 1 can be set up as a simple single-mode light, a dual mode light, or a four-mode light with memory mode.
It is optimized for 14500 use, but is quite respectable using standard AA batteries. I look forward to what Lumapower has in store for future TRUST Series models.
The Model 1 also offers a variety of carrying possibilities with the reversible, deep-carry clip.
The construction and detailing are well executed, and the beam is useful with a broad spot smoothly transitioning into a bright corona. This is a solid offering in the crowded single-AA market and is definitely worth a look!
