Kaiser Opal Lamp 75W

The even light distribution from that inner coating is exactly what I needed for my prints, no more hotspots on the paper. It's bright enough that I can work comfortably without squinting, and it’s been rock solid every session since I swapped it in.

The inner coating really makes a difference—light on my easel is noticeably more even than with my old bulb, with no hot spots. Prints are coming out more consistent now, and the 75W is plenty bright for 8x10 work.

Installed this in my enlarger and the 75W output is noticeably brighter than my old bulb. The even light distribution is consistent across the whole baseboard, no hot spots at all.
