Is there a real way to tell if your lights are emitting the correct spectrum for corals? I don't want to just throw out bulbs after 6-12 months. And if that's all you can do, where do you throw the bulbs? I think halides are toxic, as with the new energy effecient bulbs. They contain mercury which retards learning capability in small children.

You might be able to use a PAR meter to compare your initial bulb values to current:

Here's a nice article on PAR measurements:
