Like i said many pages before.....
It all depends on three simple things - how much money i have, what exactly will that money buy me, and will that what money buy me will be adequate and meet all my expectations....
If you have 1000$ budget, and need a unit to light 20g tank..... Then, yes, your money will buy you best possible thing, and it will be adequate....
If you have 200$, and need to lit 500g tank..... Then no, whatewer u can buy, will not be adequate and you will not be happy.....
If you have 1000$, and knowledge, time and will, then sure, you cannot buy adequate light for 500g, but you can make one yourself...
Of course, prices are example, not exact numbers what you can or cant buy....
