the other thing it do get my attetion with quatz halogen lights the T-3 or T-4 bulbs are not designed as to run off axis of horzontail due the heat build up and it will cause early bulb failure there.
I did see it many time when some handyman do this set up and burn up the halogen bulb rather very fast
and the other thing with this size of fixure it is commmon to overwattage it espcally if fixure is rated for 300 watt and it is common i did see some people jammed 500 watt halogen bulb and do wonderful damge from overheating
Merci, Marc
