For optimal air cooling
How it works
Air Flow through the Armature
1) Cool Air Cools the Electronics
2) Air Passes through the tunnel above the reflector which cools the reflector
3) Air turns around and goes through the nanotube which in turn cools the lamp
4) Air leaves the Armature at 140 – 158 °F
If the air used to supply the Nanotube is cold less air flow is supplied, vice versa if the air supplied to the Nanotube is hot more air is supplied.
The supply Air MUST BE CLEAN and DRY to prevent contamination!
The fan can be controlled by room temp. The luminaire will not break if there is no air flow
