C4 Review

Unerwater Kinetics C4 e-LED torch review
Nice simple page this one. Just some ramblings on my experiences with the UK C4 eLED diving torch.

It costs around £40 and is worth every penny. Contained within is a 5W white light (colour temp around 5500-6500k) LumiLED LED. The LED should last around 10,000 hrs plus and has no filament to expire.
There are 2 flavours of this torch. One where you put batteries into it and one that is rechargeable. I bought the battery version and was really pleased with it.
Now, first and foremost, it will not suffice as a primary lamp in the UK, however, put it into a clear water situation and it excels. Why? Well, it's lightweight, so saves carrying a cannon around, and will easily do a weeks worth of night dives (45 - 60 mins per dive) on one set of Duracells. As the light temperature is similar to a cloudy day, you get to see the true colours of what's underwater rather than the yellow / orange tinged glow you get from a filament based torch.
The torch has 2 power settings, the light output being pretty similar regardless of setting. As with most things made by Underwater Kinetics, it's construction is pretty much bulletproof. I did try a set of rechargeable batteries in the torch, but the reduced voltage of these (1.2v per cell vs 1.5v per cell for alkaline) did result in less light output. So based on that, I'd only recommend good quality alkalines in this lamp rather than higher capacity NiMh cells.
Quite clearly, it's not going to rival HID or higher power filament diving lamps, however this unit won't burn out if turned on out of water and is perfectly adequate for places like the Red Sea or the Maldives etc.

So, if you are looking for a more compact holiday torch then the C4 eLED is a fine bet. A nice backup is the eLED version of the mini Q40.
