Anyone Thinking of Dumping LEDS and going back to Halides

This ones gone quiet :)

I came across the Phillips coralcare LED fixture recently, a light with scientific backing. A light which is tempting me to try LED again :)

What I can say is it has a lot of LEDs in the 420nm

40x 6500k
32 x RB
16 x 420
8 x PC-Amber
8x cyan

They found growth and color to be the same as T5, which is promising.

The lights give no shimmer and look more like T5 due to their frosted glass cover.

Anyone running these ?
 
Right now, converting pounds to dollars, this would be a $900 fixture for 30% higher efficiency per unit. For proper coverage I would need 4 of these 190W units compared to my single 60" T5 fixture.

Good grief. :)

Right now I have ~500W of lighting. At full power these LED's would be 760W. Assuming I would not run them at 100% I would still end up pulling about the same amount of power (blue at 100%, white at 50% assumption).

I do think this is a good test because it will show performance when coverage is similar. This, IMO, is why the Ecotech test did not show any acros, their coverage was wrong.
 
Where are you seeing you would need 4 fixtures to cover what a 60" T5 fixture does? At most I would venture to say 3 fixtures from everything I have read. What are your tank dimensions?

These are the first LED fixtures other than the Mitras that have really caught my eye. I am anxious for there US availability and for someone to give them a fair shake. From what I am seeing, they are extremely promising!!!

A fair point, I have a center brace so I would have to do 4, 2 would not be enough. There's still the cost problem though. I can replace a lot of bulbs and go through a lot of electricity before they will pay for themselves.

I did not see the led mix in your link. It's interesting that they have gone with PC-amber as a broad spectrum supplement to the cool white and have eliminated the red. They sure have a lot of non-blue spectrum in there.

I like the white reflector's they've implemented. I wish there were a simple DIY equivalent, but I've not found one yet.

I agree with Mark, they are 'spensive.
 
I'm going to build up a DIY unit with exactly the same LED counts, for my 50 cube.

What i cant find is what power they are running on each channel to get the right spectrum. I'm thinking for viewing they run the unit with the white and amber channels down, but for the growth and color tests they ran them whiter. Frosting probably plays a big role in coverage, this would effect efficiency to some degree.

Ill be using aluminum channels, that work well with active cooling, id say i wont be running anywhere near the 190 mark over a 50g cube.

i still think lani LED are the best design.
 
I want T5's on my 20 g Nuvo but can't find a decent looking unit that would fit a 23"x13" tank. I was looking at ATI and the smallest one covers my entire tank and rear sump. Anyone know a decent set up that looks modern please DM me.
 
Just know that is an unbranded Odyssea fixture. A lot of Ebay sellers buy them unbranded hoping to sell them in spite of the horrid reputation to people who may not realize what they just bought. If you do buy it, before you plug it in, open it up and inspect the wiring, connections and routing of the wires.

Hmmm...

Doesn't seem like much work for such a savings. Even if you just go ahead and buy an entirely new ballast your still way under a name brand price...
 
Maybe, maybe not. Price two MH ballasts and two T5 ballasts, proper T5 reflectors (which may not fit) and it becomes much less of a bargain. It is also possible that the poorly manufactured ballasts burn while you are not home. If you want to play around with switching, get a used unit as a base to play with.
 
I'd give my endorsement to the Hamilton Cayman Sun. If you get this conbo fixture, please consider mapping out the PAR map under it?

I wonder why no one makes a triple light fixture with leds, t5s and halides?

It would be pretty sweet to be able to program a cool sunrise/sunset mode with the LEDs as well as storm, cloud cover, lunar cycles etc. Then the halides could handle the max intensity/high noon/full sun aspect with the t5s to supplement and decrease shadowing.

Combining all 3 technologies, with a wifi controller/controller compatibility with detailed programming, would be the ultimate light.
 
Probably because of heat and LED'd dislike for it. It can be done, I made my floating canopy with LED, MH but with VHO instead of T5.
 
I'm supplementing my MH with red, blue and UV LEDs...

I plan on reversing the artificial blue morning and nights with red to simulate what really happens on the reefs...

red/yellow dawn and dusk... blue morning and afternoon... blue and UV midday... then UV for moonlight
