Hi Slyspy
Be careful when selecting your lamps. Standard lamp sizes will not fit a Rio 180.
You will have to buy Juwel lamps if you want to replace them and they will cost you an arm and a leg (anywhere between £15- £30 each
).
I have a Rio 180 and have a plan in place for when mine finally pack up.

Hope that helps.
Oh, and the bottom line is, use which ever colour lamps you like the look of. The plants will adapt
😀
Check out this really useful thread by JamesC to give you some idea of colour combinations too.

Finally, I was advised by someone round here (with more experience than me), that the only time you need to change a lamp is if it doesn't work when you switch it on, or you fancy a different colour
😀 . The manufacturers will have you believe that they need replacing every 6 - 12 months because the output drops, and they want to line their pockets with your hard earned. Well the output will drop over time, but it won't stop your plants growing.
Spend the money you save yourself on some more plants
.
