new hood a few bulb questions

we just got a solarmax he its dual t5 with a 10k and a 67k and in between is 5 blue leds for nightime. my question is the bulbs in it are 21w can you change bulbs in these to like 24 or 39? do we need a ho hood to use diff wattage bulbs they make our hood in a ho version but we didnt want the 54w bulbs that it comes with.

Re: new hood a few bulb questions

You can put bulbs rated for a higher wattage in, but your fixture will only power them with the 21 Watts - the power output of a fixture is determined by the ballast and endcaps, not by the bulb you put in. Similarly, if you got the 54W T5HO, you would NOT want to put a 21W T5NO bulb in or the fixture would destroy the bulb.

You could have gotten the T5HO fixture and just run one bulb and removed the other, if you wanted. As is, you're stuck with 42 Watts.

Hope this helps!

Re: new hood a few bulb questions

ok another question this hood lets you independently control each bulb which i love but the blue led strip (moonlighting) that has no control so after i turn all the lights off these blue leds stay on. I have done a ton of research and alls i can find is opinions on blue led moonlighting some believe algae thrives off it which i do not want and others say its only a few leds very dark and weak and wont be enough for algae to grow? also im afraid fish would like darnkess sometimes wouldnt they? whats your thoughts on this?

if you think the blue leds that are on all the time are useless i can get this for alot cheaper, T5 Dual 36" HO Aquarium Light Strip 78W Marine Cichlid Tropical Fish 39W Odyssea | eBay
