Just buy one with the right beam angle, and you are off. Right? Well maybe, but probably not. Because there are a few more things to think about before you can be pretty sure that what you buy will do ...

I’m something of a headlight nerd. In a previous life, I retrofitted HID projector headlamps onto my 2009 Honda Civic Si for better light output. I’m planning a similar project for my beater 2015 VW ...

Maybe everyone else has known this for ages, but at last there is enough information on led and collimator data sheets to work out how far one should be form the other to get the specified beam. This ...

Once it’s up to snuff, the sheet is immersed in a nickel bath, and galvanized. From there, it can serve as the master for mass replication. The researchers claim that the machine can produce fiber ...

Everyone loves LED matrices, and even if you can’t find what you like commercially, it’s pretty easy to make just what you want. Need it big? No problem; just order a big PCB and some WS2812s. Need ...

LED Engin, a venture-backed California company offering high-power LED systems for specialty lighting applications, is set to become part of Osram, after the two parties agreed an acquisition deal.

The light intensity curves for LEDs, regardless of whether they are collimated with a lens or reflectors, follow a bell shaped curve (often referred to as a “Lambertian“ curve). The 50% intensity ...

[Garrett] over at MaceTech was approached by a friend who needed a light-up mohawk installed on a Viking helmet, and he needed it ASAP. Now, [Garrett] does tons of work with LEDs but it’s not every ...
