Electronics Weekly sometimes requests device samples.
It is not that the team doesn't believe the specifications we are sent every day, it is just that it can be tricky to put 77dBA or 33 lm into perspective.
The latest items to arrive in the post are a Cree MC-E power LED development board and some matching Eva collimators from Finnish lens maker Ledil.
The specifications are on the respective web sites, but what are the devices actually like?

Check out two new in-depth articles recently made available on the site. They cover Optimising standard-definition video on high-definition displays and an in-depth consideration of the direction of light.The availability of large-screen HD LCD TVs and plasma displays is driving the popularity of digital-TV broadcasts and HD-signal interfaces.
However, the ability to support legacy sources with the highest quality remains an essential requirement. The 3-D-comb video decoder is a critical processing block that can heavily influence overall system performance.

Three nights in a freezing shed, and finally an LED light sits on the front of a bike at Alice Towers. Following the over-heating disaster, I chickened out of soldering the re-made parts of the Mk V together and this time glued them with Arctic Alumina Adhesive.

To be fair, I cannot say I know as much about photons as an earth worm because I have no idea how much worms know about quantum physics.
So instead I will say I know almost nothing about photons*.
This has not stopped me being puzzled by this article

Inspired by comments made on one of the Electronics Weekly blogs, I thought I would have a go at estimating which led-collimators combination would not dazzle on-comers if used in a vehicle headlight.
A dazzle-free beam must be possible, because the IQ Fly pictured here can do it.
Now, I have to admit that I am winging the calculations here - so any corrections or refutations to the following are welcome.
