    Wink2 [The Lite Review]: Emisar D4 - The Quad Wonder Review

    Preface

    The original review can be found on TLR's website: Click Here
    For most, this light may not need much introduction, it being one of the more popular flashlight introduced in Q4 2017.
    It’s hard not to see why it is that popular – single & small 18650 form factor hitting 3,000+ to 4,000+ lumens with a great UI to boot. Or is it really too good to be true?
    Oh and before we begin, just want to give a special shout-out and thanks to my buddy, Job, for lending me his personal light for as long as I needed for this review.
    Note: This is a V2 model but with the pre-Noctigon 4XP V2 MCPCB.

    Packaging & First Impressions


    This is what the light will come with as shown below.

    • Packaging is minimalist.
    • No clip is provided to pocket carry the light (available for purchase separately).
    • The threads and o-rings were mildly lubricated. Threads were rather smooth and clean (no gritty feeling).
    • The side electronic switch requires a somewhat firm press to activate and is possible for accidental activation in pocket.
    • Anodizing of this sample is uniform in color but thin.
    • Battery compartment holds a LG MJ1 (3500mAh 18650 flat top unprotected battery) with sufficient room for a slightly longer battery width (those with button tops). Protected 18650 batteries do not fit and are not recommended for this light as well.

    Top (NOTE: The box should read Model: “D4”, LED: “XP-L HI V2 3A” and Color: “BLACK” [due to mix-up of boxes] instead):

    UI (User Interface)


    UI for this light is good for Every Day Carry (EDC) as it is extremely straightforward to use.
    Switching ON and OFF is done by the side electronic switch on the light.
    From OFF:

    • 1 Click – Last brightness level used – last mode memory / 100% of 7135 chip output if after LOCKOUT mode has been deactivated.
    • 2 Click – Direct access to TURBO; 2 Click again for Last brightness level used or 1 Click to switch OFF.
    • 3 Click – BATTERY CHECK mode; 2 Click again for TEMPERATURE CHECK mode.
    • 4 Click – Activate MOMENTARY mode (LEDs will blink four times upon activation); repeat 4 Click to deactivate MOMENTARY mode (LEDs will blink twice upon deactivation).
    • 6 Click – Activate LOCKOUT mode (LEDs will blink four times upon activation); repeat 6 Click to deactivate LOCKOUT mode (LEDs will blink twice upon deactivation).
    • 8 Click – Activate BEACON mode; 1 Click to switch OFF light.
      10+ Click & HOLD – THERMAL CONFIGURATION mode; release switch when the light gets hot to set.
    • HOLD (~1.5 sec) – Direct access to MOONLIGHT and the light will keep ramping up to TURBO; release switch to set light at desired mode level (150 levels in total).

    From ON:

    • 1 Click – Light will switch OFF.
    • 2 Click – Direct access to TURBO; 2 Click again to go back to last mode.
    • 3 Click – same as above (3 Click from OFF).
    • 4 Click – same as above (4 Click from OFF).
    • 8 Click – same as above (8 Click from OFF).
    • HOLD (~1.5 sec) – Light will ramp UP/DOWN till TURBO/MOONLIGHT, release switch to set at that level; HOLD again to reverse ramping sequence. When the light reaches 100% of 7135 chip output, the light will blink once during the ramping sequence.

    *Ramping Sequence is extremely smooth and ramping from either direction takes only ~2.5 secs for the 150 levels.*
    For those who prefer a picture for the above UI instead, the below is courtesy of Tom E & ToyKeeper on BLF.

    The light is temperature regulated on the FET modes (outputs above the 100% 7135 chip are all FET modes), i.e. the output will drop when it gets hot and will increase again when it cools down. Hence, setting the THERMAL CONFIGURATION is recommended as this light gets HOT real fast on Turbo.

    Form Factor


    For flashlights that are intended to use on a daily basis (EDC) and for possibly a long period of time, form factor is extremely important.
    This light fits a medium sized hand easily. Switching between overhand and underhand holding method wasn’t an issue and its (lack thereof) weight certainly helped in it feeling rather well-balanced on hand. Due to the lack of knurling on the light’s body, it tends to be rather slippery, especially with wet hands/gloves.
    The light could certainly do well with a provided clip. However, attaching and then removing a Convoy clip on the light causes some of the anodising to be scrapped off at those point of contacts (as seen in the pictures below).
    It can tail-stand perfectly without the slightest wobble.










    Beam Style/Beamshots


    For this quad lights, the spill, corona and hotspot is somewhat predictable – often producing what is known as a “wall of light”. With the sheer output from the LEDs used, the beam is still sufficiently “throwy” for recognising items in the near to mid-range distance.

    The above beam profile is rough interpretation of what is seen when white wall hunting. The beam has a rather large circular hotspot with some slight corona and a squarish spill (current gen models will have Noctigon 4XP V2 MCPCB installed so the spill will be circular in nature). There are no rings in the beam when whitewall hunting/in real world usage.
    Note: The top left optic may appear cracked to some but it is part of the Carclo’s design (flaw?) whereby it actually is a “Gate Crop”. The beam profile is not affected by this phenomenon.

    All of the beamshots taken below are done so with the following camera settings (LOW: 6″, F3.5, ISO100, Daylight WB, MID: 0.8″, F3.5, ISO100, Daylight WB and TURBO: 1/10, F3.5, ISO100, Daylight WB).
    Some pictures have been adjusted slightly to depict as close as to what is seen in real life. The distance of the light from the door is 4.6m.


    Control shot:


    LOW (<1 lumens):


    ~MID (145 lumens – 100% of 7135 chip):


    TURBO (4300 lumens):


    Mode (Output) Spacing


    Mode spacing (150 levels) appears to be progressively brighter to the eye and the modes are well spaced enough to be able to select just about any level one would need. With that in mind, TLR tend to view mode spacing as battery life indicators (amount of runtime left) rather than the specific output (lumens).
    The MOONLIGHT mode is perfect for those bedtime runs or with night-adjusted eyes. And this light is capable of going all the way to the extreme end of sheer output with just 2 Clicks.

    Is it just me or is it plain mesmerizing viewing triples/quads in their lowest modes?

    Tint & CRI


    Emisar did not disclose the CRI (Color Rendering Index) for the LEDs used in their light. For this light, a guesstimate would be in the 70ish CRI ballpark. The tint on this light is 5000K.
    There are some tint shifts throughout the beam profile. The hotspot is almost creamy white whilst the corona and most of the spill possessing a neutral white with slight pinkish tint; and the extreme end of the spill having a squarish ring of slight yellowish-green tint. This is however, not as noticeable in real life.

    Waterproofness


    Note: Prior to this test, the head was disassembled and the O-ring was found to be between the lens and optics. The O-ring was then placed between the head and lens instead for this test.
    The light was subjected to warm water submersion, followed by cold water submersion and left under room temperature running water tap whilst running on Turbo.
    No signs of water intrusion in the head, switch or body was seen.

    Lockout Capability


    Both mechanical & electronic lockout is possible for this light when needed, like during transportation in a bag/pocket.
    With the slightly protruding side switch, it is highly recommended to lockout the light when not in use.

    For electronic lockout, see above “UI (User Interface)”, on how to activate and deactivate LOCKOUT.
    A quarter turn (anti-clockwise) of the tail portion of the light will enable mechanical lockout.


    Summary


    To sum up, we believe that the most important part of any review is if given the chance to purchase the same light for our own EDC or to gift to our loved ones out from one’s pocket (wallet), would we still do it?
    For this light, it is a definite YES.

    The smooth ramping, straightforward UI and the ability to have anything from MOONLIGHT to crazy output TURBO are just some of the many reasons to get one, if you have not. However, all that output on Turbo also means that this light is a heavy battery-guzzler.
    As the quote “with great power comes great responsibility” goes, this light definitely is befitting of it.
    A few seconds of this light in Turbo on any dark materials will leave a 4-hole burn mark or even catch fire; so please do remember to lockout the light before placing it into any pocket/bag.

    The only gripes we had for this light were the lack of clip provided and we hope for a day when Emisar uses a more flush side switch button like on the Zebralight lights.
    Here’s a bonus size comparison picture of the light next to TLR’s recently reviewed Zebralight H600w Mk III.

    As with all gears, two is one and one is none.

    Stay safe,
    The Lite Review

    Hey Thanks!

    Can you provide a video of this flashlight setting some dark material on fire? Melt I can believe.

    Thanks.

    So, no direct access to low or moonlight from off, unless they were the last mode used?

    You press and hold from off for direct access to moonlight. Here is the UI diagram...



    I just saw the box had the wrong label and is the XP-L HI 3A version.

    Many flashlights will set material on fire by putting material on the lens. There is several videos on Youtube and other sites.

    Several videos of an Emisar D4?

    The statement from the review indicates shining on any dark materials. Thinking I'm not the only person that questions this flashlight setting something on fire like that, and we are not talking about putting a highly combustible product on the lens.

    Did I say a D4?

    The OP was just warning people that the light has the potential to burn holes or possibly even start a fire, so to lock it out for safety.

    Many high power flashlights will start fires so, I think it is a valid warning.

    Thanks Tachead!

    Just wanted to put out a reminder.
    It isn’t fun anymore when something starts burning in our pocket area!

    No video but here is a quick phone quality pic of holding the D4 (on Turbo) about 5mm away from a black chair for just 2 seconds.

    Here is a shot of a cheap flashlight holster where I placed some powerful flashlight that went on somehow. The host in there now has a red filter.

    The comment in the review summary is a bit broad and without evidence regarding setting dark materials on fire.

    The later comment about 'even for the ladies' is not appropriate for candlepowerforums.

    The title of this thread referencing this flashlight as a Quad Wonder may give a clue as to the reality about this flashlight setting 'any dark materials on fire'.

    Did a little experiment. Hope it is of substance. Emisar D4 TiCu with Nichia 219C 5000K (really nice color temperature and excellent tint but not for the warm folks) with Sony VTC5 fresh off the charger. Black construction paper with torn (frayed) edges: lit easily with a match. Supposedly the Nichia gets hotter than the other emitters, right? The copper head lets the turbo run a little longer, that is until the copper heats up, then the heat shedding ability is perhaps lower than the aluminum D4.

    Some rather dead-time on the video while I get a volt reading on the VTC5; sorry about that.

    Do you see smoke? (2:30)

    The reason for not including additional photographs/videos is to not promote this "side-effect" of having that much power/output on tap. It was mentioned here as a precaution to those who already own or are planning to own a D4.

    After all, a flashlight is meant to simply produce light and not to potentially leave burn marks/start a fire.

    The comment was actually meant as a candid remark but I have removed it, in case the mods happened to feel the same way as well.

    No, the review was titled "The Quad Wonder" as the D4 really is a wonder light - the sheer output, small form factor and price point almost seems like an impossible feat; considering that just 1~2 years back, most 18650 lights were maxing out at 1000 lumens only.

    Sweet raw Titanium D4, she's a beauty! How are the threads like for the head & tail sections?

    Thanks for the video taken, I don't get why the black paper doesn't burn but the following are some possible reasons off my head?
    1. Difference in ambient temperature conditions (it is rather warm in Singapore with almost perpetual summer temperatures throughout the year).
    2. Age/Cycles used of the VTC5 cell (a brand new LG HG2 was used for the review).
    3. The D4 must be on Turbo (max output - no stepdown) to enable any burning; any lower and it will not be hot enough.
    4. Difference in LEDs (219C tend to run much hotter and usually stepdown almost instantly as compared to XP-L HI).


    Unfortunately, I have already returned the D4 to the owner. If he is free, he might drop by with a video of it.

    Heh I'm the D4 owner I recently got the D4ti 219c version while he was testing it and I thought all was well, until i decided to take out the D4 XPL-hi and try to smoke some dark paper out of it.. turns out didn't have any dark paper so i used a brown mcdonalds takeaway bag, was just expecting smoke as below



    Until this happened after a few seconds..




    I filmed a short video of it in action here : https://www.edchub.com/2018/01/29/d4...burning-video/


    Here's the interesting part, this D4 xpl-hi was the second one to be tested off a fresh efest 10amp cell, the first test was done using my D4Ti, and it failed to burn the paper, only a little smoke, and this was using the exact same battery.. The XPL-hi is no competition, it produces a lot of smoke within seconds and a burning hole after

    Going to swap my LEDs over to the D4ti now to test, driver should technically be producing the same output so let's see..

    Snipped for brevity...
    Thanks bud for stopping by!

    I'd imagine if it were black paper it would have lit up even faster, which just goes to show how important to lock-out this beast when carrying in our pocket/bag/enclosed material.

    Thankfully the D4 Ti models can still be mechanically locked-out by twisting the head (if the electronic lock-out is not preferred)!

    seems to me that mechanical lock out is a damned good idea and a very healthy practice to get in to.

    I would t wish to burn anything deliberately or accidentally so if I d go ahead and get one, that is going to be rule No. 1

    Yes indeed but don’t let this little reminder discourage you from experiencing this beast in person!

    Totally. It never goes into a bag or pocket without unscrewing the tail cap.
