Here is a DTL Elite Series premium long life 20+ year LED control.The housing is a little taller on these,it has a photo transistor eye,1.5 fc turn-on level.
Nice! Does it come with a 20 year warranty to back that claim up? ... I didn't think so. DTL makes pretty good PCs though. Granted, I don't know about the new ones but the ones installed here between ~1996 and ~2001 seem to hold up fine.
Oh wow that's actually impressive, though what's the point of a 10-year warranty when the life is 20 years long minimum? Seems like it should be rated 10 years if the warranty is 10 years. They're basically saying "It's supposed to last 20 years but we expect it to only make it half that long."
