I'm guessing this LED panel is primarily intended for retrofitting in traditional fluorescent and tungsten bulkhead lights, but it could also find use as a backlight in a lightbox. It's not got an isolated supply, so it should be regarded as being live with reference to ground and mounted in a manner that does not pose a shock risk.
In Europe the Quicktest is available from most large electronic component suppliers like CPC, RS, Rapid Electronics etc.
A Quicktest with US/Canadian colours is available on eBay at:-

And a three phase US/Canadian one too:-

    Hey Big Clive, Is it possible to replace the constant current driver with another that underdrives the LEDs, so they last longer? That would be the ideal no-solder solution for an electronics noob, since it's possible to order the LED rings without driver from China.

    Maybe this could be worth a follow up video.

    I don't know if you've covered the other version of this type of light, its in the shape of a star with about 8 individual strips that can be removed. I was just wondering if it would be worth it to take the individual strips and place them in rows to make a really cool grow light. Im a super nooby to this, so I'm assuming I simply solder a wire going from the metal ends on the strips back to the metal connectors on the small driver they come with?

    is this driver any better than the capacitive dropper to power up 220v dc 18 pair of 4 parallel led in series?

    Would it be possible to replace the LED driver and run this of a 12v 24ah SLA battery?
    Both this and the death star you reviewed would suit an application but I'm limited to a solar charged battery.

    Clive , could you do a video on replacing halogen s for LEDs and how to modify the power supply to handle to reduced load or add a ballast to pull the extra wattage needed. I just replaces 6 20 w halogens with 4w LED G4. If I replace all 6 the LEDs light very dimly. If I put back just one old halogen all light brightly. I guess there is a minimum load of 40w or so. Should I replace the halogen transformer psu with an LED driver or can I modify.

    I have somewhat of a similar LED ring in my kitchen inside of a housing. I think it's a quadratum flushmount LED ceiling light. That bit of kit looks like it would be a direct replacement for the LED aray that's inside of it (as it mounts the exact same way as the kit you have here.)

    That would be awesome as a camera light..

    I really like the way you explain the circuit diagrams

    first time I've heard you say 'milliamps'. Usually you say mill-amps

    Is it so that when replacing a blown fuse on a multimeter, the amp meter might become inaccurate because the new fuse might not meet the same resistivity characteristics? (Assuming the replacement follows the same rating).

    i have 3 of these at home, replaced my current florescent tubes with it, its a neat invention.
