Now simple 2 mode off the switch, standard and high analogue operation,
plus downlighters operate upon connecting battery. IP 68
5metre waterproof (short periods only due to cable plug). Lamp redesigned to improve intrinsic reliability and
suitability for hard caving. EX stands for "Extreme use"
some inquiries I have done duration tests on power banks and it appears that
some change has been made in either management circuitry as I now longer get
a slow diminishing output up to 24 hours on the 2 cell version tested.
(Does not apply to Scorpion TGX which is designed differently)
A Dragon was tested on standard mode and gave virtually full
power for 12 hours then diminishing for a further 3 -4 hours when it died
after about 16 hours.
I have changed the description on this website and in my
literature, and apologise for any misunderstandings caused.
Of course, a diminishing output will reach a state when the
level of light is useless. It’s possibly the management electronics that are
now shutting off at 2.6V rather than 2.5V, which really was a bit low.
cell power packs supplied prior to February 2014, Trigons and some X3000s.
It is highly recommended that you upgrade to a new flat pack (as
shown below) for increased lamp power and burn times.
Price is £60 plus postage.

D1800: Revised model
has less functionality but more intrinsic reliability. Not much different to
the last D1800s shipped with upgraded glands and switch boots.
