You know what it’s like, you’re walking through the local dollar store (or pound shop, for those in the UK) and you see some interesting looking cheap LED lights. So, you buy a bunch of them and turn them into a DIY LED panel. At least, what’s what Dave Knop (AKA, Knoptop) did, and it only cost him $13.

Each light takes three AAA batteries (as Dave found out after he’d bought a crapload of AAs), and they’re attached to the baking tray using little velcro strips that come supplied with each light. The lights all turn on and off with a simple toggle, and when you’re using eight of them together they turn into quite a bright light source, which he then attached to a light stand using pipe cleaners (this is why the holes in the tray were important). As mentioned,  the CRI and TLCI on these aren’t going to be very high. So, I probably wouldn’t use them for serious work unless colour really isn’t important. But if you’re just starting out and you’re looking for a cheap option – or if you’re planning to convert it to black and white anyway – these are a fantastic way to get you going for as little cost as possible. That being said, they don’t look too terrible. If you’re handy with a soldering iron, I’d probably sort out an alternate power supply, though, so that you don’t have to deal with 24 AAA batteries.
