Re: New 100 Watt Lamps - Meter at 18. Is this normal? TA beds with electronic ballasts (and the mag ballasts too) do not need boosters so your voltage for those beds are correct. Lamps run best at a temp. of 108°F. That is the internal temp. of the lamp and you won't be able to measure that with an infrared thermometer. The acrylic surface should read 78-80°F after the bed is warmed up for a couple of minutes while running. 18-20 mw/cm² A+B on the 5.0 meter are normal for 100 watt base beds using non-reflector lamps. The higher numbers you see commonly posted are for VHR and HP beds. |
