The bulb thing is about colour changes over time - which, admittedly, you may not notice, or may not notice enough for it to bother you at all. (As an old-timey film photographer, I dealt with bulbs both as light sources for shooting and as enlarger light sources. A 100° colour temperature shift isn't all that visible to the unaided eye, but it does make a huge difference where colour criticality matters. My bulbs tended to be good for 10 to 50 hours before they really needed to be swapped, even though they were still clearly bright enough.)
- Diederich 7y agoThat is true, we did notice a slow color shift over the years, but that was fine by us. (:
