The lighting is making them morph more quickly.
But it's not the lights... it's the warmth.
Simple as that.

These tads? Tads in mid November?
Have they been positively identified as
Gray Treefrog - Hyla versicolor
or
Cope's Gray Treefrog (Hyla chrysoscelis)

Both of these species have a breeding season that peaks in late spring.

Could you post some photos. I would love to see them

I agree --- they should be released... as Amy mentioned "on a nice warm day"
into a small body of water.... ie a small pond or even a swamp
