INCANDESCENCE
What is this? Only a light bulb? Oh yes, but what a light bulb! Glorious Philips Photolita-SM PF217 from the old stock (only a few left). It has an internal mirror, satinated and frosted, it gives a very precise 3400°K but has a relatively short life cycle - approx. three hours. Still quite good for a decent photo session and almost enough for a complete recording of Richard Wagner's "Tristan und Isolde" :D
