Please post what brightness has the image projected by enlarger, you can obtain the level in different ways:
> A lux meter, like the (Amazon) "Leaton Digital Luxmeter" , 0.1Lux capable, $16 (interesting to hace something like that in the darkroom)
> Use a Lux Meter app for the smartphone, it uses a sensor that's near screen for screen autobrigth feature. It gives too high readings with perpendicular directional light, but still a reference.
> Use DSLR/SLR photometer and say the f/, shutter speed and iso
