Silly question, I know....

they're t5 cool whites. uncertain of the exact bin now.
It has to be said there is no way I would use antifreeze or the like in a system like this. The inevitable leak would be fatal to the tank.

I'm in the UK. My house has a winter temperature of 10-15ºC. We wear jumpers (and hats and scarves!)

Stage is appropriate. The inspiration for the next set of lights will be stage lighting.

I've been thinking about how tanks are lit lately.
Why go for even coverage when clever placing of lights could enhance an aquascape?

The numbers don't look right.
Replacing 190W of tubes with <50W of LED's isn't going to give equivalent light.

Good hint on the look behind you for sunsets! More than that though, anytime you are out shooting you should check behind you.

MITx electronics course. Looks useful
I came across this the other day.
It looks like it will fill a gaping hole in my education, so I've signed up for it.
It's MIT's prototype online course and it's being run for FREE.
That's a great...

So long as you think of a modular design, it doesn't much matter which way you initially jump.
24 XP-G's might be perfect, but are likely to be driven quite hard for that perfection.

Excelent, look forward to seeing the build progress.
$200 is going to be tight...
Hopefully though, you won't be looking for new bulbs in 12-18 months and you can feel smug about the lower wattage...
