while browsing through the catalogs of European (German, to be precise) light equipment suppliers I noticed that professional 230V halogen lamps are increasingly hard to find... it almost seems like 240V lamps are the new standard?
Does anyone know why?
Mains voltage (single phase/phase to neutral) in Europe is still 230V +/-10%, so why are vendors increasingly introducing 240V bulbs? (Or is the manufacturers?) 240V lamps in a 230V (+/-23V) grid are very inconvenient... It's easy to dim down a 230V lamp if voltage is too high. Boosting voltage to 240V is not so simple in comparison... Even assuming mains may be (if we're lucky) at 240V (well within the tolerance range): when pulling a few amps (as is typical at a film set), voltage typically will go down quite a bit due to line losses, moving away from 240 Volts (and making the lamps warmer)...
Am I missing anything here?
