Hi there
This topic has been discussed a lot in the past but technology goes fast and I was wondering if in 2024 there was a realistic low-consumption/low-heat LED bulb alternative to our traditional incandescent bulbs...
Of course for multigrade paper we need something with very particular wavelength or filtering won't work as expected...

I've read somewhere that "Osram Parathom 4000K LED 10w " was delivering consistent results with no variation in grading when compared with tungsten bulb.
Does any of you work with a LED bulb in his enlarger ? With which results ? And if yes, which bulb ?

Multigrade/color head, cold head and Heiland products are not what I want to talk about... Only traditional enlargers with condensers and a bulb as a light source.

Thank you
