Terrible Advice Tuesdays: The wattage of LEDs doesn’t matter because half of the watts are for cooling fans.
The rest of the story: Let’s fact check this one:
1) A lot of LEDs for aquariums don’t use cooling fans. The lack of cooling fans means no watts are dedicated to a cooling fan.
2) The cooling fans I see on aquarium LED fixtures are usually cooling fans borrowed from the computer industry. A quick scan of 120mm computer fan yields an average wattage draw of about 4 watts. If the terrible advice was true, then most aquarium LED fixtures would max out at about 8 watts, which isn’t a lot. 8w might get the job done for a pico tank.
If you happen to run across a LED fixture for an aquarium and half the watts of the fixture are going to a cooling fan, RUN!Browse the Store! Questions?
