Light Source for Reading pH Test at Night

[aylad]

I use either a cloud for the background or the flourescent light in my kitchen. It's actually easier for me to read it with the light than in bright sunlight.

For those times when I test after dark I use a GEPE light box.
It provides 5000K color corrected light, runs on batteries but also has an AC adapter.

This allows me to do the testing poolside without having to hike down the hill to the laundry room.
