The Lady Galadriel gave Frodo Baggins a crystal phial filled with water from her fountain that held the light of Eärendil's star. The phial was to provide Frodo with light in dark places.
I guess it would be fair to say the modern version of the Lady Galadriel's light could be the LITEBUCK. For something good came out of the 2005 '7/7' London bombings - the genesis of LITEBUCK Strobe Marker was formed.
The inventor found himself underground on a tube train without any light. Once he had been safely rescued, one of the many thoughts to run through his head was how to tackle the lack of light on future occasions. "Wouldn't it be a good idea if we could all carry something really small and handy that we could use to signal or give us some light in situations like this", he thought.
I give you the light of Eärendil, our most beloved star. May it be a light for you in dark places, when all other lights go out.
The resulting impact resistant LITEBUCK module has three modes that can be activated by one hand: rapid flashing strobe, slow flashing strobe, or permanently on, providing low level illumination for approximately 100 hours.
LITEBUCK has designed a variety of housings that a strobe module can be inserted into, including a buckle and a split bar. Thus this 18 gram light can be easily attached or buckled to back packs, body armour, helmets or diving equipment.
The LITEBUCK has a 50 metre 'waterproof' depth rating. It is also a potentially useful piece of kit for divers who hike, cycle, climb or play outdoors in harsh environmental conditions, or for those that just want the option of carrying a small light on their person. Available in red, green, white, yellow and infra red LED colours.
