Watt's a lumen?
To understand the lamps you need to understand
some common terms. Amps are the measure of electrical current that flows
through a circuit of part of it. The now obsolete Oldham lead acid caplamp bulb runs at
1 amp. Volts technically defined as potential difference or electromotive
force can be equated to pressure like the pressure of water in a tap. Turn
on the tap the pressure drops and you have a current. Watts* are units of
power and are arrived at by multiplying the amperage by the voltage. The
standard Oldham caplamp has a 1 amp bulb and the battery is rated at 4
volts, so its classed as 4 watts.
(* Defined as a duration of energy equal to 1
joule for 1 second)
Lumens are units of light that are actually
produced at source, and should not be confused with Lux which is a measure
of light falling on a specific area at a specific distance. The Oldham
lead acid caplamp produced
48 lumens of light for a consumption of 4 watts. LEDs produce a lot more
light, a Cree XML2-U2 will produce approx 3 times this at 1 watt.
A 220volt 100 watt light bulb produces about 1000
lumens, this is the league we are in with my lamps.
However, lumens do not tell the whole story,
second to this in importance are the optics, its no good having a powerful
LED if half the light goes to waste. This explains why you will sometimes
see a lamp rated at say 500 lumens beat one rated at 600 lumens.
The relationship between lux and lumens is fully
dependant on the way that the light output of the LED is managed, this a
bare emitter could have a very high output expressed in lumens, but would
have a very low lux, equally a miners lamp such as an Oldham DL 16 will
have a very high lux for its relatively low lumen of 90 lumens. This is
because all of the light generated is focused into a very tight beam.
So if we widen the beam say by 100%, in order to
maintain the lux rating and therefore the throw, we would have to increase
the output of the LED by 100% to 180 lumens.
We have a wide range of caplamps suitable
for caving and mine exploring, ranging from the lightest currently
available to most powerful. Expensive? well not in the sense of some on the
market. Our most popular lamp is the Dragon EX which weighs in at only a
mere 125 grams. Our Lynx X12 produces on full power
7000 lumens which makes it one of the most powerful mining and caving lamps
available to purchase in the world. Our X2000 produces over 2000 lumens of
beam or floodlight power. Beware competitors which quote total output as a
mix of beam and bare emitter.
All the lamps share some common features:
#1 At least 2 independent circuits.
#2 Power packs are solid cased and based
on Lithium Ion (Li Ion) technology. They are waterproof, blow resistant,
explosion proof, and economically priced, and can be carried as a spare and changed underground
without fiddling with loose cells or inserts. All power packs can be, and indeed its
recommended, 'top up' charged. They cannot be overcharged. They contain
the very best available genuine Sanyo/Panasonic/Tesla cells.
#3 All lamps
now carry a back up circuit independent of the main electronics, this is
incorporated into the beams. 8 and 12volt series lamps have additional
#4 All lamps are waterproof @ 30 minutes at 1 m
water column; IP 67 and
have no silly pointless flashy modes (Hidden flashes on X_Basic)

switch is universal on most of my lamps. Very high quality: here is the

What they are saying
No recreational helmets are currently manufactured
with lamp brackets. My Lynx and Dragon aluminium lamps are designed with a 40mm spacing
between holes so as to duplicate the fixing for the Petzl bracket. If your
helmet has one of these simply drill out the rivets to fit your lamp. The
bracket can be refitted if desired using our stainless steel screws.
If you need a bracket for one of our
now discontinued Oldham based lamps or someone else's, these links are useful.
