Arrow Olight SR52UT Intimidator (XP-L HI, 3x18650 or 6xCR123A) Review





Olight has released the SR52UT Intimidator which is updated version of their SR52 Intimidator, powered by 3x18650 or 6xCR123A. This features a stock Cree XP-L High Intensity (HI) LED and in-light charging option. The light comes in a very nice plastic carry case with cutout foam. You can see the important features and specifications on the front and back of the packaging.
.
.


SR52UT comes with micro-USB cable, warranty card & manual, holster, USB Vehicle adaptor(attached), spare o-rings.
.
.
Manufacturer Specifications from Olight's website & manual :

• Features a CREE XP-L HI LED, maximum output of 1100 lumens, and a beam distance of 800m
• Three brightness levels plus a strobe mode: 1100 lumens, 550 lumens, 80 lumens, and a 10Hz strobe mode
• 99% light transmittance rate through the tempered glass lens that features a two-sided anti-reflective coating
• Built-in charging circuit for the 18650 rechargeable lithium ion batteries through a built-in micro USB charging port on the body of the flashlight
• Heat sink body design allows more efficient heat dissipation
• Features three parallel battery compartments including reverse polarity protection to prevent improper battery installation
• Powered by an 18650 battery featuring a protection board with a bulged battery positive end
• Wide input voltage range from 3-9 volts compatible with CR123 batteries but CANNOT be chaged inside the light
• Flat tail cap providing the ability to place it upside down
• Lanyard hole on the end of the tail cap
• Anti-scratch type III hard anodizing aluminum body


.
.










The hard(type III) anodizing is a matte black and no flaws on my sample. The labels are quite minimal, with manufacturer name and information respectively on the head and tailcap. All labels are sharp and clear in bright white against the black background. There is a large raised checkered grid pattern all over the body tube. The light has no tail switch. Fit and finish looks very good.
.
.


The light has 2 parts. The body is one piece with the head (i.e., the head is integrated into the body and is not removable). The light opens at the tailcap only. The SR52UT gives you the option to choose between 3x18650 or without batteries. My review sample came without the cells.
.
.


The light has a flat stainless steel bezel ring and a blue o-ring. The head has a clean looking cylindrical design with nice looking scallops machined around the rear area which serve as an anti-roll feature. There's an electronic side switch just on the cooling fins for on-off and mode changing. The side switch cap is not the hard plastic or metal button, but it looks silicone rubber. The switch cap is slightly protruded from a metal surround, but quite set lower position than the head. This means that the risk of accidental activation may be reduced.
The switch has a good feel to touch and has typical travel, which produces a clicking sound when pressed.
.
.


The light doesn't use a battery carrier, instead has cut-out wells for the cells. The cells are arranged in parallel (i.e., 1S3P). All the positive terminals of the cells are going toward the head. So you can run the light on a reduced number of cells (1x18650 or 2x18650 or 2xCR123A or 4xCR123A). However this will give you lower runtime.

Note that the small positive (+) battery contacts in the head are not raised, but slightly recessed. I think these recessed contacts have a reverse polarity protection function. It means only small button-top cells work in the light (i.e., true flat-top or wide button-top cells will not work). The built-in cut-out wells do accommodate my longer and wider 18650 cells.
.
.




The light uses AR coating lens where the purple hue is reflected on it. The reflector has a smooth pattern. The reflecotr is well polished with no noticeable finishing flaws, and well-centered XP-L HI V2 flux bin LED sits at the bottom of the reflector cup.
.
.


The body tube is covered in aggressive raised checkered grid portions. The grip is very good. Some scallops machined on the head would have helped further too.
.
.


One of the distinctive aspects of the light is built-in micro USB charging port for 18650. The micro-USB port (rated at 5V 1A) is hidden behind a sliding cover which seems hard plastic material. The charging port and charging status indicator are in the upper part of the body tube. Note that this charging status indicator works as a low battery warning indicator as well.
.
.


The screw threads are square-cut of good quality. Threads are well machined, and anodized which allows 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 sample.
.
.


There are three large plastic columns that work as spacers and hold the cells in place as you screw down the tailcap. These columns and negative springs with a bottom piece inside the tail spin freely. There's a wrist lanyard attachment at the tail end.
.
.


The Bundled 1m USB charging cable came with the vehicle power adaptor with a USB plug. You can connect the micro USB cable to the USB port of your PC or to your electric outlet by a AC/DV USB adaptor. But the adaptor was not supplied from Olight, so I used my Galaxy S4 USB adaptor (output DC5.0V, 2A) for charging the 18650 cells.
.
.


There is a low voltage warning sensor under the small LED indicator just beside the USB port. The red light will light up and flash slowly when the batteries are running low. In this case, you need to change or recharge the cells.
.
.


When you plug the light into a power source, the LED indicator beside the micro-USB port will light up red to indicate normal charging condition. When charging is complete, it turns to constant green. Also in case battery installed wrongly or tailcap not completely screwed, it just shows green and the red light flickers at the same time.

Note that you can charge 1x or 2x or 3x18650 in the light, thanks to the 1S3P parallel arrangement. The fewer you charge in the light, the faster the cells can be charged. This is because that the charging current will not be split across the cells.
.
.
Charging in the light
I did two charging tests with 3x18650 (2600mAh) protected cells in the light, using the USB adaptor (output DC5.0V, 2A). The voltage before, under and after charging are as follows :





I used the Xtar USB Detector "VI01" to measure charging current and input voltage.
For first charging test, I used a discharged 3xVicLite 18650 (2600mAh) protected batteries, resting voltage were 3.09V for all. As shown in the above table, the initial charging and input voltage were respectively 0.72A and 5.31V. You can see the charging current and input voltage over time. Max. charging current was 0.90A at 7hrs 22mins charge in my test.
After 9hrs, the current was down to 0.13A. After 9hrs 15mins, charging was completed and the LED indicator went green. The resting voltage of all 18650s was 4.19V at this point. It is reasonable and good for charged voltage.

Note that the charging current is fluctuating between 0.00A and 0.01A when the LED indicator was green. Even if I remove the batteries from the light, it is still the same as 0.00A~0.01A. So this small current seems to be a standby current to check whether the cells are fully charged or not (i.e., to check the batteries condition), in my view.

I left all charged 18650 cells in the light to see if the light does charge them continuously once fully charged. After 9hrs 25mins, the resting voltage of all 18650 was 4.18V. This means the light will not charge the cells after full charge.
.
.


After the first test, I removed the batteries from the light and just left them as they were for about 5hrs. The resting voltage of all cells was still 4.18V at that point. I was wondering if the light will charge the cells again. So I inserted the cells into the light and found that the light starts to charge them. It means that the SR52UT in-built charger does charge the same way as the normal chargers.

In just 17mins, charging was completed and the LED indicator went green. The resting voltage of all 18650s was 4.19V again. I left all charged cells in the light for about 6hrs and found the resting voltage of all cells are 4.18V. Therefore the light will not charge the cells after full charge.

Olight confirmed that full charged voltage is considered as from 4.15V to 4.22V. But if the voltage of the cells drops to 4.05V, the light does restart to charge the cells in the light.
.
.
User Interface

There are two modes (i.e., general mode & strobe mode).

On-off and output switching is controlled by the electronic side switch. A quick press and release (i.e., click) turns the light on, and another quick click turns the light off.

Holding down the switch will proceed Low -> Med. -> High, in repeating sequence, when on. To select your desired mode or output level, just release the switch. The light has mode memory, and remembers the last output level used when you turn the light off and back on. Note that it turns on in last output even after a battery change.

A single click from Off will access to the memorized output level.
A double quick click will activate Strobe directly, whatever mode the light is on (even Off).
The strobe has no memory. A single sustained press of the switch will return to the previous output level

The light has a lock-out function to prevent accidental activation. Hold the switch down for 2secs from Off, the light will be turned on temporarily 2secs in previously memorized output, then turn itself off and be locked out. It can't be turned back on until you hold the switch down for 1sec. Note that this lock-out function will be persisted even after a battery change.
.
.
Standby Current Drain

Due to the electronic switch design, the SR52UT is drawing a small current when the batteries are installed and the tailcap fully connected. I measured this current as 4.5μA. considering a 18650 (2600mAh), that would translate into hundreds of years before they would be fully depleted.
Note that the standby current under the lock-out mode is the same as 4.5μA. So the lock-out function seems to have no effect on the standby current. This is not a concern. But I would recommend you store the light physically locked-out when not in use for a long period.

Measured Dimensions

.
.


It is reasonably compact for a 3x18650 light. The light has a bit wider body tube to accommodate 3x18650s, but shorter length than expected. The wall thickness of the body is reasonably thick (2.7mm), and the light feel solid. Overall build quality is very high.
.
.
PWM


The light shows no sign of flicker by PWM at all output levels. I notice there is no buzzing sound at any levels. The light seems to be current controlled.
.
.
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 and Med. is as above graph.

On High, the light is semi-regulated on 3x18650 (i.e., slowly drop in output). You will not be able to notice the drop in output over time in practice. It's quite acceptable for the class using 1S3P arrangement. In my view, you will get flat regulation on High on 6xCR123A, thanks to higher voltage.

On Med., the light shows perfectly flat regulation before dropping off in output. I assume it will show perfectly flat regulation on Low as well.
.
.


Overall output-runtime efficiency seems good.

Beamshot
1. White door beamshot (about 50cm from the white door) on max. output on 18650 (2600mAh) VicLite protected cells
- ISO125, F/8.0, 1/25sec, Auto white balance


.
.
- ISO125, F/8.0, 1/100sec, Auto white balance


.
- ISO125, F/8.0, 1/800sec, Auto white balance


.
.
- ISO125, F/8.0, 1/2000sec, Auto white balance



The light shows a narrow hot spot and medium spill beam against the stock dome-on lights.
The tight hotspot is fairly well focused and its tint looks pure white on my sample. A soft corona surrounding the hotspot is slightly yellow. The spill beam width looks almost the same as the M3XS-UT and clean with no noticeable artifacts (i.e., the overall beam profile is very good). The overall beam tint is nearly pure white.
.
.


This is comparison beamshot between Olight SR52UT and M3XS-UT (about 50cm from the white door) on max. output on 18650 (2600mAh) VicLite protected cells.
Compared to M3XS-UT, SR52UT has a pure white tint.
