Thanks for the reply.
I was just told to give an update on my water parameters and he just gave me a few strips to see and record the info thats all.
I agree on the fact by looking at plants gives me an idea on how the tank is going, however I have only started planting the last 2 months and just recently upgraded to a 180l tank in which I think possibly the lights need chaning.
But I will learn along the way.

Well, maybe it would be better to give us an idea of what problem you're having and the context under which the person asked you to perform a test. There may be a good reason, and there may be a way of determining the information other than via the test strip.
There are only 2 real reasons that lights absolutely
need to be replaced:
1. When the light switch is selected to the ON position the light bulb does not illuminate.
2. You prefer a different color light bulb for aesthetic purposes.
Again, we really need to understand the context in which you feel these actions need to be performed. Are you experiencing some difficulty with plant growth? Did someone advise you to perform a test or to change your bulb as a result of this difficulty? This is my immediate suspicion. If this indeed is the case, then I can categorically tell you that in both cases the answer is no, you don't need to do any of these actions, but you may need to perform other, more effective actions. Could you elaborate a bit more?
Cheers,
