The Photon I (and its follow-up Photon II
) is a tiny flashlight, on a key ring, less than an inch long but incredibly powerful. Made from almost-unbreakable polyurethane (scientists tried to break it by doing science stuff on one, but to no avail) it contains a similarly tough LED. It will illuminate your own bit of dark whenever the occasion arises. Kept on a bunch of keys, it is the best small torch of them all. The white-beamed variety illuminates in full colour; in blue, a Photon will naturally make things glow blue.
So there you have it - a virtually unbreakable, incredibly strong torch that weighs less than a Â£1 coin (Sterling, overseas Firebox fans), its variant and its colourful cousin. Photon is about to make its mark.
