THANK YOU Marty

What wattage was the Bulb you were using? If it was low wattage (25 or 40 watt) it probably lit fairly bright from the heater load of all the tubes.
Typically, a 'dim bulb' setup will use bulbs of different wattages (something like 25, 40, 75, 100 and maybe 150). A high wattage bulb will barely glow (if at all) at normal current draw whereas lower wattage bulbs will glow brighter at normal draw.
