Are you asking about just the bulb?

From what i know, the yellower colored light could be a bulb with a lower "K" Level, something maybe around 4500K - 5500K?

As for the blue light... it could be a bulb with just a blue hue in it... i know in HK they sell bulbs like that, but not sure about the US?

Top tank is a 50/50 10K and 460 nm actenic blue, bottom tank looks to be around 6.7K natural day light which is heavier in the green/yellow spectrum to simulate natural sunlight. Look for bulbs by their temperature rating (in degrees Kelven). 3300 is a warm reddish light with 10K being a cooler blue light, the 50/50 bulbs 10K/Actenic are a combination. There is also a nice looking bulb that is a combination 10K/6700 that gives a nice light but I've only seen that in CP not in T-8 or T-5.
