That's a variation almost without a difference... tho of course no light at all would be even safer.

Of course you don't stare at any of them. If you wear ordinary vision glasses and are careful (I keep a sheet of black vinyl around and over the set up, so stray glances are more or less harmless) that's safe enough, if you like looking at the light, get black glasses.
