As you might have guesses, the 454 has an emission spectrum peak at 454nm which is smack dab in between the fluorescence excitation peaks of 420 and 470nm. Even if this bulb doesnt ping exact known fluorescence excitation peaks, this light should still bring out many colors which are largely under represented by most light spectrums available in the aquarium lighting market.
