Zebralight SC700d review
Zebralight is a Texas based leading supplier of compact high intesity LED flashlights and headlamps. The review you'll about to read about the Zebralight SC700d is one of their latest models which sounds extremely promising and I'm very much looking forward to reviewing this little beauty. Let's dive in and see how it performs!
What you'll get:
- Zebralight SC700d flashlight
- Carton box
- Spare O-ring
Although it costed me quite a fair amount of money for the size, this review is already going to thrill me. I have long been looking to get a Zebralight for review, and here it is.... the Zebralight SC700d. Upon receiving the flashlight I am a little disappointed about the packaging, other, cheaper flashlights come with more accessories and a higher quality packagin. Inside the box you'll find a pocket clip, 2 biefy spare o-rings and a manual. Apparently I read through it before I can continue the review!
Handling of the light
I was kind of surprised seeing this 21700 light being soo tiny. It could definitely had been called the tiniest 21700 light I suppose. Wow. The second thing I noticed is the extreme light weight. I know some people like to have their flashlights/torches as lightweight as possible, but to me it feels a little too light. Maybe I'm just too much used to the heaver kinds of lights, with more heatsink etc. So I'm very curious how this bad boy is going to hold up when temps are rising. The manual states it has a built in temp control, so I guess they will reduce the output considerably at a certain point. We'll see soon.
Also, the switch is rather deeply recessed, which definitely can be a pro. And it's okay when using it barehanded, but a con when using gloves. Fortunately I don't use gloves that much. So not really a con for me at the moment. The good thing about this is that it doesn't accidentally turn on in your pocket! Which is a problem with some side lights with electronic side switches.
Take a look at the photograph below, and see the size in my left hand. I have mid-sized or even small hands.
- Yup, and very stable!
- Take notice. Once its attached it is very very hard to move it around or to take it off. So you'd better make sure in which direction you want to attach it Before you clip it on.
Build Quality and Anodizing
As I mentioned earlier, it is extremely light. So light I am wondering how it will handle the heat it will produce. Besides these "feelings" the light is built very well. No blemishes on the anodizing could be found. There is however something I am not 100% happy about, and that is the prints. The brand is laser engraved looks like, and not just printed on the anodizing. When you look up close it isn't very sharp. Besides the prints you can see in the pictures below, there is no other text anywhere on the flashlight.
The pocket clip seems to be of pretty high quality, and feels really stiff. I am not afraid of losing this light when attached to my pocket.
Threads and O-rings
This light may have one of the best threads I have ever seen. This could be deceiving because the SC700d arrived with a large amount of lube on the threads. And at first glance I thought the smooth unscrewing was because of a very beefy O-ring that made is feel smooth as silk, but it wasn't the o-ring, but the lube.. So I'm not 100% sure if's the lube or just the awesome machining. Also, you'll get 2 extra o-rings in the box for backup.
1 thing I noticed that the body and head are made of 1 piece, and that only the tailcap is separable from the body, and not the head. This makes it a little more difficult for modding, or if you ever needed to replace the LED.
Another point of interest is the tailcap. See the pictures below. The tailcap has some sort of micro springs (which seems to be a Zebralight thing after all) All these little stubs can be pressed in. On the driver side you have the same micro springs. I personally have never seen them before. Zebralight has the following to say about it: "Beryllium copper springs in all pogo pins for extremely low electrical resistance"
LED, Lens Bezel and Reflector
The LED used in the Zebralight SC700d is a CREE XHP70.2 Neutral White, with 5000K. This is a bit above the average Neutral White to my understanding. But the interesting thing is the High Cri.. its supposed to be 90+. In person it seems a bit greenish compared to my other XHP70.2 lights.
The reflector is made of aluminum and has an Orange Peel coating. The Lens is clear and has some kind of coating, maybe UV/AR coating?
The stainless steel bezelf finishes it it all off.
Flashlight manufacturers mainly show dimensions in millimeters.
- SC700d length : 107 mm
- SC700d head dia: 38 mm

- Press and Hold: Low Medium High and repeat.
- Single click: High
- Double click: Medium
- Three clicks: Strobe
- Four clicks: Battery capacity tester

Not electronic. But you can twist the tailcap about a quarter and you have it mechanically locked out.

Not visible with the naked eye at least!!! Great
The Zebralight SC700d doesn't use 186500 or AA batteries, but rather (unprotected) 21700 lithium batteries. This is the first flashlight Zebralight made that takes 21700 batteries. The battery I bought with the flashlight was a Samsung INR21700 40T for max Amps. It is supposed to be able to push more than 30 Amps which is insane. But the Zebralight doesn't use that much of current fortunately, but I didn't want the battery to be the weakest point, and therefore chosen the famous INR21700 40T while buying the Zebralight.
Parsitic drain Zebralight SC700d:
- 0.02mA = 2.35 uA ?
Measured with a Samsung INR21700-40T in a homemade 50cm integrated sphere.
I used a Convoy S2+ with a steady 137 lumens for calibration...And used a professionel lux meter called: Hagner E4-x for testing. I double checked the output with a cheaper Skytronic LX-101 lux meter and both were extremely close.. About 1% difference from eachother! The numbers below are from the Hagner.
- High mode H1): 2740 lumens (7.86Amps)
- Medium mode (M1): 165 lumens (0.28Amps)
- Lowest mode (L1): 2 lumens (0.01Amps)
Zebralight's lumens are 3000 - 192 - 2.1 lumens. So they are higher than I measured, but not extremely much. Only about 10%, and you wouldn't notice a 10% difference in output! The Amps I measured with a Fluke 77III so I can't measure very low amps.
Measured inside a carton box. Lux calculated first to percentage and then to Lumens. 100% is 2740 lumens according to my earlier Lumen test.
Within 20 minutes it drops to about 900 lumens. This output continues to 107 minutes before dropping to 26 lumens. The light keeps running at 26 lumens till I turned off the flashlight. The battery was at 2.75 Volts after taking out at the 150 minutes mark. I believe it would be able to run a little longer, but at this Voltage, this was enough in my opinion. THe most important numbers can be seen from the graph below!
Runtime: 107 minutes.. I would call this the actual runtime.
Passing the 2,600 lumens it's not the brightest LED flashlight, but more powerful than 99% of the flashlights currently on the market I would add.
---- coming soon!
