CXA3590 Build Plan

[REALSTYLES]

I should make a song.

Doer this fits you

That was...great. I came here to learn. I don't have anything to contribute to the threads here, that's why I don't step on them, until this one. I aint about nuthin, he can say what he wants about me. This guy Doer cast shade on some pretty good people...you, church, greengenes, positivity, others.

Doer, you are mean spirited and this thread has your character. You don't have to be this way but this thread will always have this tone. Let this thread die.

I should make a song.

The difference you ego monster, is you produced an ugly piece of shit!! And then your re-do turned into a slightly different but more ugly piece of shit.

Neatness counts. Proper planning prevents piss poor performance, Your follow along, get it done, suits you. But, it is no hallmark of fine engineering.

Any fool can color out side the lines. And good morning to you, too.

I think this thread should be moved to a non-LED section but, whatever.

Doer, you are mean spirited and this thread has your character. You don't have to be this way but this thread will always have this tone. Let this thread die.

If anybody has a creative way to provide Doer with an image of himself, have at it! He's a rich target.

 

[Doer]

I visualized the angles and decided I do need reflectors. 90 degree is better. And now I can see the entire fixture becomes virtually 90 degrees.

 

[Doer]

A hood makes much more sense than all that work.

 

[Doer]

Just looking at my end cap idea. I think this will work.



But, it is probably easier to just shorten the length by 2 inches and make 2 flat end caps out of that, (or from scrape, of course.)

While the reflector design will give you 90° angle, the hood one will not.

Well, this thrown together artist rendition will not. But a real hood can be bent to get a 90 degree angle a little more easily that these the Sketchup models. I left off the ends on this one for clarity.

You see what I mean? Or are you saying No Hood can beat 16 Reflectors? That is surely true.

I have a 36" pebbled aluminum hood that can be any angle I want, within reason.

 

[Doer]

Something like this, then?

Just reminder that this particular hood wouldn't be 90°.
If you can get/are willing to pay for Ledil reflectors I'd use them instead of the hood. It would be actually simpler as you can attach them to a holder very easily.

I know and thank you again, for your input. And I am just juggling some trade offs.

- this hood is UN-doubtable something custom. I've not seen bigger than 36" (I could shorten rail to 36")

- don't need screws, if I don't attach a holder and a holder is needed for Ledil.
- without screws, I can go to thin wall aluminum and get much better Thermal Conductivity. (unless I am thinking about that incorrectly)

What do you think about .125, vs .25 thick square tube for this?

Honestly, I didn't even think about attachment w/o screws.
About that thickness...IDK. Thicker tube could conduct the heat more evenly over the whole area eliminating hotspots under the COBs. On the other hand the thinner one means less resistance between the source of heat and cooling medium. A simulation might very helpful there.

So you're gonna use a pump and a radiator (active probably?) in a closed circuit?

Actually, I have a water light set up that is ballasted on a 100 gal garbage bin full of water. The sump pump is suspended in the middle bottom of the water column and is almost soundless. I ran that for a year on 1000w HPS, so I have a pretty good idea of how it performs around here.

By the end of the day, it was about 90 degrees in the water, and it loses all that overnight, since I set it up to radiate, so did not insulate it. It was sitting on the north side of the house, in the shade.

In the morning it in was 72 degrees again.

That will get a luminous curve in LED that is perhaps enjoyable. A low start with cool water, and a lower finish of the day with warm water.

lol.

I am glad some troll I ignore amuses you.

Jeeze, where are all the smart ass replies.

 

[Doer]

The Aluminum tubes arrived.



This makes me very happy.
