cant
identify

It is on the power supply board

it is labelled RT1 and looks alot like a small capacitor

it has the marking 8S100L on it

it is one of the early components on the board (next after the

fuse-
F1))

please help as i have repured the rest of the board but am sure

that
i
need to replace this aswell as it is showing scorch marks



Highly likely that RT means Resistor - Temperature (dependant).

It will be a NTC inrush current suppressor.. Since the unit is not
likely to be using more than a couple of 10's of watts at most you
could use one such as this

Could this device (or similar) be put in series with my halogen puck
lights that keep blowing bulbs - and would it help?



Could you please explain what a "puck light" is?

I am familiar with the standard halogen downlights operating from ac
mains supply via a transformer but not knowing the specifics of your
particular halogen I couldn't say whether the NTC would help.
