Excess
weight and heat are problems encountered when using
industrial H.P.S lights. To solve this problem I
relocated the internal ballast.

List of tools
required: Screwdriver, Hacksaw, File, and a Drill. As
with all electrical tasks safety comes first, make sure
your lights have been off for a few hours as capacitors
can hold a charge.

This is the light untouched.

Remove the four screws to separate
the main sections.

Remove the mogul base.

Mark the outer case and
seperate using your Hacksaw.

Mark out the holes needed to
mount the lamp holder.

Drill the holes.

Remove the two wires that ran
from the ignitor to the lamp, replace with 9' of
heavy-duty cable, later this will connect to the lamp.

Here is another view of the
wires. Remember to check your cables are properly
connected, electricity can and will kill if mistakes are
made.

The earth wire
must be connected to the ballast case, WARNING:
DO NOT USE A LAMP THAT HAS NO EARTH WIRE BETWEEN THE
BALLAST AND THE REFLECTOR.

Drill a hole big enough to put
the cable through and connect it to the lamp holder
using the previously drilled holes.

Here is the lamp holder mounted
and the earth wire secured to the reflector.

Job done.
