- My Satellite Setup
- A little less analogue, and a lot more crap.
- My Location
- UK
As per the title, what would I need to check the frequency of a single (or narrow band) frequency of light, towards the blue end of the spectrum ?
I have some bulbs here I need to test for their outputs, some are grow lamps with various different LEDs illuminated, plus filament lamps that are in the region of 40+ years old in boxes. Some may contain rare gase or mercury so I need to be sure they are within specification.
Thanks in advance
