This unit is a very common UV nail polish curing unit available cheaply on ebay. It uses four 9W UVA tubes like the ones found in insect traps and UV exposure units. The unit has the option of continuous or timed operation with a fixed time of two minutes. I experimentally exposed a piece of photo sensitive PCB laminate with a transparency and piece of picture-frame glass to keep it all flat, and it exposed fully in the two minute cycle. This makes it one of the cheapest PCB exposure units available.
Inside there is a single PCB with a microcontroller based timer and an electronic ballast that uses a single drive circuit, but has a choke for each tube. For the money this unit is very impressive.

Hi Clive. The factory output of my unit appears to be 47V for each lamp however I want to modify it to drive some 9W UVC bulbs I purchased that specify 60V. When I plug my new bulbs in I can hear the starters in them tinkling away trying to start but there doesn't appear to be quite enough power (I suspect just lacking voltage). My next step is to reverse-engineer the circuit to work out how to boost voltage slightly but thought I would ask here for suggestions on which component I might look at to bump the output voltage to 60V – just in case you are still reading comments on these historic videos :).
Possibly the first appearance of the Poundland screwdriver?
I can't seem to find any videos that prove UV LED nail curing lights are actually strong enough to work. I'm always skeptical. Any insights? Wife is considering doing her own to save money. Thanks!
I have this exact model UV lamp and one of the bulb sockets isn’t working. I’ve had a look, everything looks fine, no loose wires. Any ideas what could be the problem?
On my UV cure lamp the power cord is only two wires brown and green I'm struggling to find where they r supposed to be connected to please help angel baby😩😩🙏
Doe's anyone knows to tell me what is the expose time..
Hi big clive ,what's the amps for the glass fuse
I have a trouble with this. My UV start when i plug the power supply cable and never turn off, any Idea why? I understand electronics little and need help. All buttons are ok!
That's alot of bang for your buck…
"I like the idea of pink things exploding forcefully when plugged into the mains" – is that a fetish?
so when did ya start doing your own nails? lmao
Hmm…I have seen lurid pink shitty things but I never saw one actually exploding! 🙁
Could you please find pink electronic things that DO explode upon connection to the mains supply?
im on a hell of a binge watch im on video 152 dammmmmmm lol
I bought two of these some time ago. one worked perfectly fine, the other one though kept exploding (not blowing) the fuse. Never found out what was wrong with it and the ebay seller did not want to refund, so in the end, i banged it in the trash.
You should get yourself an electric screwdriver for a couple dollars from amazon or somewhere so you dont have to screw things in and out by hand when you make your videos. it'd be a lot faster and less likely to impale yourself
