CXA3590 Build Plan

[REALSTYLES]

I buy a lot from China. I bought all this lab glass for astounding prices. And it took a while. But it all got here. I use for Extraction.

I don't think $68 at Digikey is the best price or the best way to go. Kingbite, I guess is a distributor?

Yes and they also MFG reflectors and lenses for COB's check the reflector site Kingbrite.cn

I was doing some reading on laminar flow, and you don't want that. So, the serrated heat sink might be a better profile.

Stop ordering me about, Canadian. I will post where I want and say what I want.

And you can be my project if you like. "You're the one..." What are you, a four year old?

Yup only 4...

I think @Sativied sees that if you put this light on an angle with smaller plants at one end. you are using additional gifts of the universe.

BTW, you guys do use a drill press and a template for drilling and tapping your holes, don't you?

Freehand....kiss

 

[bicit]

I use a acrylic template. Just to mark the spots, then use a centerpunch to aid the drill bit since my drill press isisn't balanced very well.

What's all the hate you guys. RUI-itits?

It's because you're not following RIU LED scripture to the letter. Essentially, you're an infiled.

I find the complaints about your design just typical... (putting it nicely). I haven't followed most of your math but I like what I see. Just a couple of days ago I pm-ed with someone about what a professional horticulture LED light looks like. And that isn't a bunch of heat sink blocks and cpu fans dangling in the air with wires everywhere... bare bulb style.

That's cute and all but look at the size of the plants they are growing lol plus they are using them in greenhouses rlmfao

Your argument is invalid (and silly). They are used in a wide variety of applications, not just glass greenhouses, and for many many many different crops. Height is not the determining factor most seem to think it is when you use multiple light sources. It's late here, I'm out for now, in the meantime, grab two flash lights and point them at the wall, move back and forth a little, overlap them... maybe you can figure it out.

Wait, I thought this was a waste of time... I've suggested this multiple times. No I'm not talking about CPU coolers. Just shorter lengths of heatsink.

Man this is a frustrating thread.

I've thought about Installing a 24" length of the 4.85" profile inside a 6" glass cool tube or PVC pipe. Then bolting 4-5 vero 29's driven at 1 amp. I figured it would be a good drop in 'retro fit' for someone used to using low wattage HID or CFL lamps and may already have a vortex fan in place for oder control. Since the 4.85" profile is fairly short it would be possible to mount the driver directly inside the tube to be cooled as well. I still may give it a try if I can score a 6" or 8" cool tube for a decent price.

I like the PVC pipe idea better because then there wouldn't be any light losses from the glass and assembly would be much simpler. Though not as pretty.

Why don't you both butt out, then, you and church?

These troll boys don't even offer concrete alternatives. They natter some smack about, break it up and spread it out. How? And why for gwads sake?

It is a shallow view, and you may as well be out burning astronomers, or throwing wooden shoes into grears or something.

For example why shorter lengths? A long length is self support at two ends. A long length just needs 1 fan. A long length cover more SPREAD.

Short sighted, passives from last year, that are not working on 900w rigs.

See, this is helping. Thanks for that. I thought about running the COBs in a glass tube. I thought about running with the tube reflector fixture, but upside down, the LEDs poke thru the top, (now the bottom) You have your flex tube connectors right there and you can put a sheet metal cap to seal the rest somehow.

In fact I was looking at cool tube grow room thinking it all needs to be turned upside down and some COBs with heat sinks substituted for the glass tubes.

But, I have a glass tube light and it is a hassle to keep clean. You really need a sealed filtered system.

And I have thought of talking a 4" PVC pipe, jig it on a table saw, and just cut a slot in the bottom wide enough to slide the heat sink up into. But, with a 3.5 inch sink you barely have enough space to put the heat sink. And if you go to 6" PVC, that is very expensive.

Although trollish criticism and assumptions can get you burned, I am seriously looking for ideas here guys. All ideas are welcome.

Debates that include no math are not.

Thanks, @bicit

Last night I had one of these pre-dream mental clear spots. I suddenly realized a way to go with the metal shroud. When I was designed a little airplane prototype with a guy, we loved what we called "Build against parts" It was a fiberglass plane and the idea is you build a part. And then build the next part, with the first section you built, as part of the mold for the next section. Very cool, since the little matching measurements to fit 3D pieces together, are molded in. The fit perfectly.

And the same thing works for sheet metal if you stay with simple curves or straight bends.

So, what head height do I want over the fins of the heat sink. 1/4"? OK. Get a piece of 1/4" wood, size it to 3.5 inches wide for the heat sink. then use both together as a folding mandril.

Dude. So true.

If I run two of these rails side by side that is 1800 w in practical the same foot print.

That is very cool! Again it looks to be the right track.

Thanks! I am an In-fiddle, and proud of it. (always one hand in my pocket just to make it fair)

Well, for me getting a drill press finally is like dating the Head Cheerleader, and Kissing her.

Sure I have hand drilled a bunch, but when I see these "tedious" comments, I know they are not really set up. And sure, if I have a 6 foot rail with even the slightest flaw in spacing orientation, line up or anything, I will mentally kick myself every time I see it.

The other stuff that makes metal work a lot less tedious is blueprint spray and a sharp awl.
I like idea of a plex template. I will probably print out a pattern and use contact cement. That is the third thing to make it easier. Attach a pattern that doesn't get taken off until the part is completely finish.

 

[Positivity]

using the holder as the template is tedious?

I think you just prefer talking down to people. Cobs ruffle your feathers?

 

[Positivity]

It's clear your intention was to anger people..

Your only fooling yourself

 

[Doer]

One troll preaches about my growing a thicker skin and the the next say I am intentional angering people, though I have a thin skin??

Stupid trolls pollute RIU.
