As a bicycle commuter, I’ve already discussed the importance of being seen on the road, and one of the most effective ways of doing so is by using good bike lights.
Front lights, in particular, occupy a broad spectrum of options. There are low-powered models that are meant to increase a cyclist’s visibility to other road users, but don’t do so well for illuminating the road. Other models rated for higher light output can cut through the darkness and light up your way as you pedal, highlighting potholes and road acne in advance so you can take avoiding action.
The light I’m reviewing today undeniably belongs to the latter category. We take a look at Cat Eye’s Volt 1200.

OUT OF THE BOX
The Volt 1200 comes in a nice cardboard box. Inside are the light itself, the micro-USB charging cable, instruction leaflet, and the FlexTight handlebar mount bracket. This is the exact same mount used by my other front light, the much smaller and lighter Cat Eye Nano Shot (HL-EL620RC).
As an all-in-one torch-type unit, the black cartridge battery is pre-installed into the lamp body, mounting via three bolts. You can undo the bolts with a hex key and mount a spare battery if you had one, but obviously this isn’t a quick affair. Besides, the huge battery is enough for most rides, especially when kept out of the higher-output modes. At 6200mAh, it dwarfs most cellphone batteries in pure capacity. My own Lenovo P770 smartphone has quite a large battery at 3500mAh; the Volt 1200 practically doubles that.
The aluminum body of the Volt 1200 acts like a heatsink, with a row of ridges on its top. Running at 600 or 1200 lumens means this can become quite hot, which is normal. The light has a little sticker on its underside warning of this, next to the rubber gasket flap for the micro-USB charging port.
PERFORMANCE IMPRESSIONS
The first time I turned it on, I laughed maniacally. An honest-to-goodness 1200 lumens! This is a seriously strong light in Dynamic mode, and it can temporarily blind people when aimed the wrong way. The beam is so potent that it handily outshines most indoor lighting. Headlight aim becomes critical when using the Volt 1200. I find it’s better angled slightly downward, 15-25 degrees from horizontal. The sheer volume of light means you will definitely be seen – it’s best employed by illuminating your path, and by brute force it will light up quite a way into the distance.
In terms of beam shape, the OptiCube reflectors and optics tightly control it to give you a focused rectangle of light with minimal spill, instead of a floodlight effect. Some people may want more peripheral light, but I find that the tight beam works well when you’re pedaling at higher speeds.
You’d think the 214g Volt 1200 would overwhelm its tiny FlexTight bracket, but this isn’t the case. Tightened properly, I never had a problem with the light drooping on the bar at all, even through bad roads.
OPERATION
Most people will see this light and think “I don’t have use for a 1200 lumen front light!” Well, true, in most cases it is overkill. However, the real draw of the Volt 1200 is how versatile it is. If the max output was the only good thing about this light, this review would have ended already.
The five modes are all good compromises between light output and battery life. You cycle between the main modes in decreasing order of brightness using a single press of the top button (Dynamic -> Normal -> All-Night -> HyperConstant, then repeat). Pedaling along East Service Road at 10 pm, at 18 km/h average speed, I used the 600-lumen Normal mode most of the time to light up the path, while being seen by the cars and trucks that ply the route. I reserve the full 1200 lumens for short bursts in very dark spots. In the daytime, I run the HyperConstant mode, which is a constant 200-lumen beam with a 600-lumen flash strobe, and this helps with visibility.
Below are sample beam shots taken with my camera. The light is mounted such that it is around 20 degrees down from horizontal. Settings are constant across all photos: ISO 400, an f/2.8 aperture, 1/2 second shutter, and 50mm-equivalent focal length. For distance reference, the white vehicle in the distance is 100 meters away.
Perhaps the only mode I don’t use at all is the Flashing mode. This turns the light into a high-powered blinker with an annoying pulse frequency. I prefer HyperConstant for this purpose, as the pulses aren’t so quick, and the constant beam gives oncoming traffic a better way of estimating distance between you and them.
Unfortunately, accessing the Flashing mode inadvertently (a double-press of the button, accessible at any time) is done way too easily. In practice, you may find that while trying to turn down the brightness, pressing too quickly triggers the borderline obnoxious Flashing mode.
Once the Volt 1200’s button glows red, it’s time for a recharge. Left alone long enough, it will automatically step down in output to squeeze as much run time out of the battery. At 6200mAh of capacity, charging this beast will take a while, and I would suggest investing in a high-current USB charger. The Volt 1200 has a useful way of discerning between normal and high-current charging. Normal charging leaves the button glowing red, while high-current charging is shown by a slow-cadence flashing.
VOLT 1200: YEA OR NAY?
I’ll get to the elephant in the room: this light isn’t affordable. Cheapskates are going to shy away from this light from the price alone, no matter what merits it has.
That said, 1200 lumens hasn’t been priced like this before – not from an established lighting brand. Not too long ago, you had to pay an arm and a leg for a light of equivalent output – and not in an all-in-one unit, to boot. Year on year, the improvements in bicycle lighting technology have become so great that my 200-lumen Nano Shot has been overtaken by the Volt 300 three years later, which packs 300 lumens in a package that’s half the price. If you look at the Volt 1200 as an investment, in that you’re buying a torch-type light that is ahead of the technological curve for about five years, coupled with the potential of buying replacement batteries…the price tag doesn’t seem too bad.
Also worth noting is that the bare aluminum on my own unit has shown a few signs of cosmetic minor corrosion. This is most evident in the clingy greenish hard powder in between the cooling ridges (which I assume is aluminum oxide) and some blistering on the underside. No adverse effect on the light’s function, though, and it might simply be due to my sweat falling on the lamp’s metal body. The Volt 1200 is still as solid as the day it was unboxed.
You may question the value of a 1200-lumen headlight, but the great thing about the Volt 1200 is that it is so much more than that. The capacious battery, great beam control, and a thoughtful selection of modes mean that this multi-role light excels at endurance – it can be the light you need it to be. Mount it to a mountain bike, turn on Dynamic mode, and see the trail light up right in front of your eyes. In practice, while riding with the light in HyperConstant mode in the daytime and Normal mode at night, over a total of two hours’ commuting per day, the battery will last a week with juice to spare. Charge it overnight using a good high-current USB charger, and you’re good to go the next day for another week’s worth of riding.
VERDICT
Reliable, powerful and well thought-out – one of the better lights around. An investment worth saving up for.
Let's Bike, Philippines! 
Sir how much is this in Philippine pesos and where did you purchase your unit? I’m a bike to work person as well and I’m starting to invest in reliable headlights.
Glorious Ride in QC has them for sale locally. You can find them on Facebook. I bought my unit while vacationing in Japan.
