Hope Vision 4LED Standard Front Light

Beautifully machined from aluminium billet, this light packs a big punch
with its four high power LED’s pushing out 960 lumens. The Li-Ion battery
pack is now held in a custom made durable plastic case. The battery has
built-in charge, discharge and short circuit protection. The connectors
are fully sealed and totally waterproof (IP67). The single switch has a
new cycle programme, which turns the light on in ‘low’ mode and cycles
through to the higher settings.

In tests the 7.4v Li-ion battery will last for up to 30 hrs + on low and a
minimum of 2 hrs on the high setting with the intelligent charger returning
that in just 6 hours. The durable plastic case is small enough to fit under stems,
top tube junctions or slip into a jersey pocket.
The 4 LED model utilises ‘thermal throttling’ techniques to increase the longevity
of the LEDs and prevent damage to the electrical circuit due to overheating.
This works by monitoring the temperature of the Aluminium heat sink and restricting
the power when it reaches a critical level, thereby keeping the casing at an acceptable
temperature for handling while providing extended battery burn times.
Lights can now be supplied with an option of longer burntimes. This is achieved by
including an extra battery (endurance).

Lights are supplied with handlebar and helmet mount. They also now include a full head harness
to allow use off the bike whether running or just walking the dog. This head harness is now
in use with many mountain rescue teams, fell runners and adventure racers.
