Electronics question, aluminium as power rail?

[PermaBanned]

It's going to be set on an MDF base with the rest made out of aluminium sheet. 100W is the total energy, so 100W of light and heat combined. Fortunately I will mainly be testing 700-850W units so it shouldn't be a massive issue. Although I have decided to install the 120mm fan now!

So as the bulb gets hotter it gets dimmer?

BTW, voltage hurts, amps kill - be careful OP

Are you getting the lamps for free or your buying it? if your paying more than £3 each for it then a power resistor can also be had for around the same price.
