ENTER_NAME said:I did. The 67k, compared to my 10k bulb will produce different lums, because there diffrenet spectrums. Yes it does matter. One that's made for fish/corals and the other being the 67k lighting the outside of your house. There's a reason why 67k MH bulbs are not used in alot of saltwater tanks, because they help in algae growth.
It's not the mh bulb temp at 6700k that promotes algae growth. Algae growth can come from alot of things. Ie to long of lights being on to much food stuff like that. And the reason they don't use them often is because. 1 6700k has a soft yellowish tint to it. And 2. Most want a bluish tint around the 10000k to14000k range and for reef tanks the 10000k is more appropriate for coral growth and color. There is absolutely no difference from a 6700k "aquarium bulb" and a 6700k bulb from homedepo except a fancy box.
As far as the debate over lumen output or mh bulbs mr.x is correct. A mh bulb will produce that many lumans. not to pick sides but you should listen to somebody who has alot more experience and time dedicated to this hobby. there is no need to get into an argument. Let's try and get back on re main topic of led lighting and if they are good for aquariums.
Personaly I would love to go with a good set of led light. I like the shimmering effect they give off. the main advantages of led lights is they do require les power and produce less heat and you never really have to replace the LEDs. The down side is for a good fixture it is prob worth your money to just invest in t5 or mh. The choice is really up to u.
