Hi ,,

What is the different between 150w and 250w , is 250w give me wider area for lighting than 150w ?

About a 100 watts.... just kidding. 250 will penetrate deeper and raise the par throughout the tank.

250w has a higher intensity and uses more electricity (obviously). It can have a wider spread if you raise it higher from the surface of the water. If you keep it in the same position as a 150w then it will have a very similar coverage but the intensity and penetration will increase throughout the area.
