Zone VI subsequently sold a similar unit, which is what I have. It has the advantage of a sensor which connects to the zone VI enlarging timer, to alter the time appropriately when voltage fluctuations change the brightness of the lamp.
My entire musing is based on replacing the cold light, fluorescent diffusion source with a relatively (if possible) elementary LED diffusion source, incorporating equivalent light-stabilization technology of some kind.
The Heiland unit, from what I can see, plugs into whatever timer one may already have, and incorporates its own light stabilizer, which would be ideal. I just can't afford it; not now, at least.
