Ok, this is classified as "pretty" even though it is far from it... it leads to pretty.
So I build a lighting rack out of aluminum C-channel and square tube, haven't mounted it yet because I"m trying to get a feel for what lights I want over it now ... and to spiff it up a bit. So decided to test out some lights
So there are a lot of options out there for lighting, of the more known brands (Kessil, AI, Radion) I'm not really interesting in the Kessils, I like the inexpensiveness of the AI Hydra 26HD but at that price point I could go with a Radion XF15 pro (the half sized one) and they have similar power and coverage areas, of both I'd probably want at least 4 of them (48"x36" foot print, 27" deep tank). Of the "lesser known" ones (Maxspect, GHL, Orphek) the Orphek is a bit on the pricy side but claims a single V4 would cover the tank (color me skeptical) and due to a cross brace I really would left side & right side lights which puts this out of my price range, GHL 7206 is sexy nice but definitely on the high end spectrum claims that it can cover a 36" x 24" area in which case 2 would be fine, but a tad skeptical of that coverage but I could possibly believe it (although I've seen others use more), the 7204 is coming out which is 2/3rds the light at 2/3rds the price and 4 of those over the tank would work better, IMO, however that really pushes it beyond my comfortable price range., and lastly Maxspect always intriguing the Razor-X is a nice upgrade over their old Razor and a great affordable fixture, the Recurve is a neat beast but a bit too pricey for my tastes. and lastly the Ethereal ... and if you never heard of it congrats you are in the majority, they didn't push this fixture very much and I think it may be discontinued but who knows not many places sell it, and there are even less reviews on it which is really the main turnoff of Maxspect lights in general, they don't seem to have *A* product that they put out they want to do all these different things and don't really focus on one thing, why can't they just do the Gyre pump version of their lights.
Ok enough of my thinking on this subject. At least initially I decided to reuse some of the old crap I got, and I can swap stuff out with new as needed (if it wasn't for the fact that most of these companies slap all their products with MAP maybe I could be swayed one way or another... but NOOOOOOOO they want to be fair to everyplace... *pittoey*... ok that's a different discussion
). Either way this is the reason for the aluminum frame to hold the lights, so that I can adjust them as necessary and mount accordingly, and if I need to get over the tank I can raise them high enough to do so all at once instead of one fixture at a time (although if I do 4 fixtures over the tank maybe individual ones would be fine and I spent $40 and a couple days building a useless piece of aluminum junk
)
So what do I have, well I have my custom LED fixtures that I built... I want to say somewhere between Radion Gen 1 and Gen 2, it has 48 total LEDs over a 6" x 24" heatsink, whites and blues are clustered in 4 locations (think Hydra 52) and there's another line of blues and violets on top and bottom, 4 total channels. But I haven't really used them much so I think they still got life left in them. No optics either, I was well ahead of that trend before the LED makers starting ditching focusing optics for spreading optics
Each pulls about 150 watts at full power, but I wouldn't run them at full power. I have 3 of these (and a bunch of other LEDs that I feel like I'll never use and was wasted money...)
Also have a some metal halide fixtures, 2 lumenarc minis (~14" wide) the square profile ones, and 2 others Lumenbright(?) octogon profile. And I do have a 10K MH lamp (250W) and a bunch of Icecap ballasts (thanks Mario
@xcaret )
No par meter so next best thing, and I know the eye is really horrible at determining brightness levels, that is unless you're comparing against something else. That cheapy LED strip I've been using looked decently bright, however after this test it looks like a candle being held over the tank.
First up Lumenbright on the left, LEDs on the right (a single fixture roughly in the middle of the tank). My first thoughts are the LEDs are actually quite bright in comparison, there's a bit different look because of the heavy blues in the LEDs, but the MH is noticeably brighter I believe.
Side view of the tank, and quite impressed that the MH pretty much has 36" wide coverage without problem at all. Any Kessil fans want to still say a 360 is the equivalent of a 250W MH bulb? Yeah, maybe JUST the bulb, there's zero way a single Kessil is this bright or covers this much area.
So cons of the MH fixture, it's heavy as all sin, definitely would need to hang it from the ceiling and not the aluminum frame. Frame held, sure but there was a bit of flex to it, which to me says I would need to support it not only from 4 corners but also the middle (which is fine), also I would worry about mounting it too high due to the plastic in the middle of the tank. Also it's REALLY big (20" or so wide?) which doesn't leave much room for putting accent lighting on either side, and if I did run a MH it would be partially (6hrs max) which means the accent lighting runs the rest of the time.
Here's the lumenarc fixture which replaces the Lumenbright, the reflector is all sorts of beat up though, but it still puts out a heavy duty amount of light. Doesn't look quite as bright as the lumenbright fixture though, some of the rocks almost looked oversaturated in brightness in the earlier photo. While we may blame the camera on this the LED fixture is still common between both so it's useful as a reference
Still ample coverage and a single bulb in this fixture easily can handle 36" wide.
So this one isn't quite as bright, which may be due to the beat up nature of the reflector, but either way it isn't as wide either (14" wide), so supplemental lighting is still an option which is a big benefit. The downside is metal halides are off or on, LEDs allow you to ramp up and down which is a pretty decent selling point. Maybe when the PAR meter makes it my way I can do a quick test of output to see if MHs might just be overkill too, I do come from a generation of reefers where 100-200 PAR is blasphemy, needed to get high 500s at least
Lastly only the LED, which you can see the obvious bright spot in the middle, but it still does have a decent enough spread, obviously a single light isn't going to cut it but if I wanted to setup a system where the light goes from one side of the tank to the other (maybe about as useful as thunder storm simulations) it definitely doesn't leave other parts of the tank that dark.
Here I moved the single LED to within about 6 inches of the front of the tank, still pretty good spread. I only wish I had 4 of these to put over the tank
So overall conclusions, while I initially wanted to put metal halides over the tank I'm really leaning away from that now if anything due to the bulky nature of the MH fixtures, but also the on/off only nature of them is a bit of a turn off. I think I still have a PWM controller floating around (Storm controller), and definitely need (want) to do some major rewiring of everything, but I don't want to spend much more (any) money on these things if possible, because every $100 I spend is $100 that could be towards a Radion or Hydra or something. These should help grow corals initially, and I can test these versus the Radion Mike will lend me, then as I get the feeling to upgrade (or there's a rare sale) maybe get some other lights, and the DIY jobbers can be for a frag/QT tank or something.
