What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Hi Matt,

just one question....can it also light up when plugged in or getting current automatic without touching it.

With this one you have to touch it to turn it on. They also sell non-dimmer models on eBay and these would probably turn on when plugged in. If it hasn't got an on/off button then I'd assume it's a model that is on all the time.

Hi Matt,

Brilliant - ordered some already.

Love gadgets like these....

Thanks for listening

Damn you and your cool gadget reviews. I ordered five and now have to wait for them to get to the US from China.

I plan to put four of them on a four-port USB hub - just because I can.

Nice device. I have often wondered what exactly are these modern super bright LED light elementes, they don't look anything like old school LEDs.

May 25, 2016 | Unregistered CommenterFinnman

Nice find, going to order a bunch as they might come in handy.

Something I am curious about is how much power it uses whilst 'sleeping' and how much at full brightness, I have multimeters that can measure microamps and will report back here with my findings.

One thought I had for a use is for simple solar shed lighting, stick them with the LEDs face down on some sort of dome diffuser, like an empty yoghurt pot, and have them hooked up to a solar charged battery, so long as the voltage regulator & USB light don't draw too much power when the light is off.

Thanks for the video, one of your best so far. I'd like to see more torch vids in this channel

I purchased these a few months ago.

I have a nanny cam on my fish tank. At night the night vision turns on. I prevented that by buying a 4 port usb hub and attached 2 of the light/photo sensor types. So when it gets dark it auto turns the leds on and keep it from going to night vision.

Great little review, in fact always visit your page for the latest little gadgets and your reviews. One thing with this particular USB light came to mind for some reason... maybe it was the mention of China (I have nothing against the Chinese) but it reminded me of an article I read a while back, I'm not a conspiracist but it certainly makes you think...

I'm probably still going to buy some anyway!

You got a mention by Andy Ihnatko on Macbreak Weekly last week, for your review of this product, as his pick of the week.
