I just asked because the Aquarelle bulb comes in odd wattages (for the US

I am not at all sure that is the best ballast for those lamps. I think that

lamp. That lamp runs on a regular ballast that is used with T12 40 watt
lamps. It looks to me that the 36 watt lamp could run on either a ballast
for T8 lamps or a ballast for T12 lamps. I am speculating that the T12
ballast would slightly overdrive the lamp which IMHO is quite desirable
while on the T8 ballast the lamp is quite likely to be underdriven. There is
no point in installing a T8 lamp if it is going to be underdriven. You need
to ask the sales rep. what the ballast factor will be when that T8 ballast
is driving these lamps. If he doesn't know then I would tend to believe the

I did notice that the Philips thinks that the blue component of this lamp
will somehow oxygenate the water by encouraging photosynthesis in plants. I
think that is complete nonsense and sounds like a sales pitch that would be
