Ledlenser P7R Work UV Review
This is my review of the Ledlenser P7 Work UV. This unique light is shock, water and chemical resistant. It features a 265nm UV function that can detect inks, and fluids. It can also be used to identify minerals.
I took measurements of the light using my Opple Light Master Pro. You can view the data here:
| P7R Work UV | |||||
| Mode | CCT (K) | CRI (Ra) | x | y | Duv |
| Low | 3942 | 95.8 | 0.3812 | 0.3702 | -0.0033 |
| Medium | 4010 | 94.5 | 0.3787 | 0.3700 | -0.0027 |
| High | 4054 | 93.6 | 0.3761 | 0.3659 | -0.0039 |
This light is the warmest 4000K light I have, especially on low modes. I like the built-in flood-to-zoom lens. Surprisingly, I’ve been using the belt clip a lot, and I like how it lets you swivel it around so that the light can illuminate the path ahead (hands-free).
@Ledlenser provided this light for review. I was not paid to make this review – all thoughts and opinions are my own.

Ledlenser P7R Work UV
Observations and things I liked:
• I’ve used this light for over a week now and I’ve been very impressed for a few reasons. The Ledlenser ‘Work’ range is a significant step above their ‘Core’ range. This light feels like it was built for a mission. There are protective shock absorbers on the head and tail cap of the light that withstand drops from 3m – that’s pretty impressive considering it’s unlikely for you to drop the light from that distance. To top things off, it’s also rated for chemical resistance – listing oil, diesel, brake fluid, and solvents.
• Glass lens protects the focusing system.
• Premium construction – think I’ve talked enough about that already but I’ll add that Ledlenser lights have one of the toughest anodizing I’ve seen on the market. My P17 barely has a scratch on it after 12 years of being knocked around.
• Rechargeable 21700 battery. These are quickly becoming the standard in flashlight batteries – they’re high capacity and high draw, what more could you want? Also works with unprotected 21700 cells – tried my Samsung 30T and 40T with it.
• 95 CRI – higher than spec. And approx. 4000K tint. I love the colour of the beam, it’s soothing on the eyes and feels like warm sunlight.
• Magnetic charging cable – this could be a pro or con. But I like that you can take out the battery and charge it separately if you have an external charger.
• Flex seal technology and IPX68 – 1.5m, 30mins
• Programmable – you can add as few or as many different modes on this light as you’d like. For example, you could just have a low mode or a high mode. That’s it. You can also manually select modes as the light ramps up and down. Or you can have 8 different modes including strobe, UV and beacon. I like that a lot and I’m sure people using this for work and different purposes will like that too. Initially, my light came with 5 different modes, including the UV. I disabled the UV and programmed in L-M-H.
• There is a turbo mode with double press – but only lasts for 10 seconds. Then you need to reactivate it.
• The UV light is 365nm – more expensive to manufacture. Talk about 395nm light vs 365. Many objects fluoresce strongest at 365nm. Multiple uses, identifying documents, minerals and rocks, paint and plastic curing.
• I ran a ceiling bounce test on the highest mode to see how the light manages heat, as well as ramping behaviour. The light started out at 180 lux (900 lumens according to specs) and slowly dropped to about 170 lux where it stayed until 5 minutes. At that point, it suddenly dropped to 125 lux and remained there for the next 10 minutes after which I ended the test. I’d estimate this to be around the 600-lumen mark. The light was warm to the touch under the head and battery tube, but not uncomfortable to hold.
• Accessories – the holster and belt clip are actually useful. The belt clip allows you easy access to the light. You can also swivel the light forwards if you want to run the light hands-free from your side. You can even buy additional accessories that connect it to a helmet, GoPro or tripod.
Improvements/Considerations:
• The dock is awkward to use – hard to fit the light in it and align the terminals for charging. But maybe I’m not doing it right. But I don’t like it.
• Instructions are confusing. They’re pictorial and it took me a while to understand how to program the different modes.
• I don’t see many 2×21700 cell lights on the market. I can see why they’d look bulky or unattractive but I think it’d be useful in a light like this where you may not want to change the batteries too often. Of course, you can carry around some spare ones, and it’d take 10 seconds to swap them in.
I never thought I’d say this but all-in-all, the P7R Work UV is THE light I’d grab in an emergency, where I’d need something solid to rely on. The ruggedness, extended functionality and programmability of this light makes this more of a tool than a simple flashlight. For me, I love being able to customise things to my needs – It’s very simple to program the P7R Work UV the way you want it.
