Don't get me wrong, I'm not out to attack PFK, it just baffles me that they have someone like George on the staff, then publish info like this. Some newbie is probably gonna read it, go buy >2WPG for their lightly planted community tank, then wonder why there is an algae explosion
I've addressed this matter before but the general opinion is that the whole WPG thing is so inaccurate that it is all much of a muchness.Joecoral said:fair enough, shows who the newbie is then (me!). just seemed a bit much when i read it, i assumed WPG was in UK gallons
I'm assuming comparing the same type of bulb? A common household 100w bulb gives the same amount of light as an energy saving bulb of 30w. The number of photons emitted are the same but the wattage is different.ceg4048 said:High wattage of light results in a higher density of photons
Welcome to the world of engineering, we spend years learning about all the highly complex systems only to trade them all in for rules of thumb when you actually want to use themceg4048 said:There are so many variables it's just not feasible to make a rule based on these data. It is important however to understand a little bit about what is going on and to be aware of these concepts.
