Show Us Your LED Tanks

[lastlight]

That last link is interesting but really looks to be a sales pitch for Orphek (which to me also appears to be an impressive light). Hey it could all be true but I was scrolling around afterwards looking for links etc for Orphek. Sure enough I found'em.

They link to the 1350g build which is of course a large Orphek showcase... I've since heard that the fixtures they sourced are custom and not even the same as the standard Orphek lights you or I would buy from the site.

LED is a-swirl in confusion (for me at least).

Usage Guidelines

• One Radion fixture is comparable to one 250w metal halide
• Generally, one Radion fixture should be used per 40 gallons (150L) of water volume.
• Approximate surface coverage is 24x24 inches (60x60cm).

Does this refer to water volume in the tank only and if talking about just tank size, for a 90 gallon should I go for three? Really like what I see and seriously considering switching over from MH to LED now.

I'd wait for a few reviews and feedback from actual users before signing up for a pre-order. The wattage on these kinds of fixtures can be misleading as it depends on what level each set of LEDs is operating at but I would suspect 2 would be plenty for a 90 gallon.

I agree but it does make you wonder with all these new fixtures coming out each kicking up the gimmick level one more notch. It really gets to the point of not knowing what the heck is good and bad. But I do know that halides make great reefs

yeah, good point. Would suck to have blown $2 grand and not being impressed. Would be nice to have it for Xmas.

If you are talking about the 3W Cree LEDs that are everywhere now a handy way to work it out is your tank LxHxW (all in inches) divided by 324. That will give you the number of individual LEDs recommended. Although that fixture has red and green LEDs in there too which are not factored into that formula. Their usefulness is still to be determined.

Well then this is your lucky day! My name is Russell and I own at least 10 strands of LED Christmas lights, 2 LED flashlights and an LED 'spot' light (one of those adhesive stick-anywhere lights).

um.. thats a handy way to figure out how many gallons your tank is now how many LEDs you need. LEDs are based on coverage only so how many would you need to evenly cover a surface area not a volume.
