Tips for testing spectrum of black boxes?

**EDIT** - Can a moderator move this to the lighting forum? I posted in the SPS forum by mistake. @Crabs McJones

I have (4) Mars Aqua black boxes above my 150 and my SPS are growing well. Just curious if anyone has a way for testing spectrum without breaking the bank?

I have all of them connected to a VDM and can adjust blues and whites through fusion.

Seneye gives you a graphical display of the spectrum that’s pretty interesting and useful.
