TO MODIFY DISCO LAMPS TO RUN ON 9V BATTERY
a) Using suitable sharp and pointed implements, delicately remove Screw Cap 1 from Lamp Body 4.
b) Cut White wire 2 from the Screw Cap 1. The other wire should be loose as it is only trapped in the thread.
c) Separate the Lamp Body 4 from the light housing 5 by gently squeezing and then you can insert screwdriver blade.
d) Cut the black and white wires 6 as close as possible to Control Board 3.
e) Connect 9V battery to white wire 6 (-ve) and black wire 6 (+ve) via switch if required.
f) Body 4 can be refitted if required and used as battery housing.
g) Screw Cap1 and Control Board 3 are not required and may be disposed of.
Or for my solution you can proceed as below. First removing Lens 7 by loosening Screw 8 then unsoldering wires 6 carefully noting their positions.
MY SOLUTION FOR FINAL ASSEMBLY
h) Using cutters remove the end of Lamp Body 4 and file smooth.
Drill 1 hole about 3mm Ø at a suitable point for the entry of battery wires.
Drill 4 more holes at 900 to each other round the Lamp Body 4.
Clean the cut face and battery box with a suitable solvent (eg meths)
i) Stick the Lamp Body 4 to the battery box and allow to dry.
Pass the leads from the battery box through the allocated hole.
Using a single length of string thread it out of the first remaining hole, in through the next etc. ending back inside after the forth hole. Join the ends of the string. This can then be pulled out to form 2 loops that can be used for suspension.
j) The wires from the battery box can be fed through the circuit board in light housing 5 and soldered in place of the wires 6.
k) The Lamp Body 4 can now be refitted to the light housing 5 being careful to align the location pin with the slot.
l) Note these lights require 9V to operate correctly and if a rechargeable type is used the voltage will be insufficient to drive the green LEDs and the circuit will require modification. Contact Richard Nourse for details.
