First attempt at a 24-hour "Martian Method"

I had such a nice wordy post on this for you, but the server got busy and kicked me off and I lost it.

Actually this is the one I use. Should filter out all of the 400-500nm?
Your thoughts?

There are many more on the market, Am I not filtering my blues?

Gotta run, so really short version:

Actually those can have problems, due to light leakage through the dichroic reflectors used on the these kind of bulbs. And they are harder to block any light leaks on due to their higher operating tempertures.

I'd check them by looking through a Blue filter for any glow they might put off in the Blue wavelengths, but then again I'd check that when setting up any PAD system sources.

I'm late, hope that leaves you with more questions than answers. Gotta run.

Take Care, Sal.
