Energy-Saving Lamps and the Stroboscopic Effect

01/12/2009 5:23 AM

Regarding the demise of 100 and 150 watt filament bulbs.

Single flourecent tube type lamps cannot be used over rotating machinery due to the stroboscopic effect i.e. the machine appears to be stationary when rotating. Dual flourescent fittings are normally used to over come this problem. Do we have the same problem with energy saving lamps?

In short, yes. Please see this thread.

I believe, though, that CFLs are being developed with longer persistence phosphors, so the problem may not appear with some of the newer lamps.

All new 'long' tubular-lamped fluorescent fittings and most CFLs now have electronic control gear operating at 30kHZ or more. The old 2x mains frequency flicker from magnetic ballasts is no longer a problem.
