You are correct... My bad....Sorry about the lack of incandescent when I spoke of black lights...

The use of clear INC's are for a (Day time) Far Red source... When blue light is present...

The use incandescent black lights are for a (Dark time) Far Red source.. No blue light present..

INC black lights will not interrupt the flowering cycle. Therefore can be used as a far Red source during the flowering darkness..


But like the PAD manual says.... LED's for a Far Red source are much better..
