Power bank price revision. Sorry having to pay more for
cells. Absorbed into lamp prices but cannot do as aftersales.
Now simple 2 mode, standard and high analogue operation and IP 68
5metre waterproof. 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.
X6000: Replaced by X_12
SAR2: Seriously good lamp but too finicky to produce in an economically
