    Yes there is. The 420 is violet and the 454 is royal blue.

    I've tried the 454 and absolutely love them. Only reason I don't have them now is they were out of stock last time I needed to get them. I'll probably switch back to them when my current bulbs get old.

    I've tried a different 4 light combination every 9 months since I started. the 454 combos are my favorite.

    The Hamilton 14K already has a huge spike at 454. I would feel the best move is to supplement it with 420.
