Solid state ,of course ...
_Withstand high currents.
-Fast tripping .
-Immune to electromagnetic/ strong magnetic fields .
-No need for 'inductive kick back spike' protection at the signaling DC circuit .(no need for a diode ).
-No moving mechanical parts.
-Compact & Robust.
-Long service life .
Cons:
They need some cooling ,if they operate at high currents
and/ or they are of "Normally Closed " * type...
(NC = AC ON ,at "0" state of DC side )...
*As the one,you'll need probably .
" Normally Open " type from the other hand ,
needs a DC signal (state 1 ) to Switch ON the AC side.
(NO= AC OFF ,at "0"state of DC side )

Perfect, thank you very much
'in the pursuit of perfection'
A luminaire that doesn't 'click' when it turns on seems like a nice detail. Especially if there are other things in a given space being controlled. A small detail that can yield a perceived higher quality.

Next step is to make the heatsink, the inner plate & the support bars ,
into one cooling "unit " .
The fan opening is finished and also 4x 3mm holes are drilled,for the fan's anti-vibration silicone pins.
( Also visible are 4x 1mm holes.Those are 'giude markings' ,
for the heat sink to be correctly placed ,underneath the plate.
The inner plate underneath...
Heat sink placement -screw openings are being marked .
Openings drilled and edge cleaned ( countersunk ,4mm hole /6mm clean)
Same job for the 2x support bars .
Seems pretty ok .

Ok ..Now the cooling unit ,is almost finished.
8x openings for the 2x drivers attachment & 2x for the wire silicone grommets,
remain to be drilled .
Cheers.

Take both Guod's and my word ....
Any of you DIYers outta there ,who have gone or going to the 'encasing the ungly beast' way ...
(modifying/ customising metal outer cases for LED grow lights )
Sheet metal Nibbler
Truly a MUST HAVE tool !
Amazingly easy,clean and quick job ...

Will need to try that... I've been eyeing that out
Too bad my machinist bro moved away... He could build anything out of metal

Say 'Thank you' to to people who were not there or denied to help you...
'Cause of them ,you 've manage to do it yourself ....
My paps moto ..
Life itself for some of us ,is actually resembling metal working ..
Always trying to stand upright ,on an anvil ..
Baptised inside fire ..
While the hammer ,tries to flatten out ,fiercely and mercyless ...
Forging a human...
Myself ,I;m pretty sure that ,soon or later you can be your own machinist ..
I can see that happening ...
I've seen the 'passion' in your lights ...
Dunno if that gives 'extra' umol/sec in your fixtures ...
..But for sure,your passion for the art ,makes them 'glow' ...
And you know what I mean ...
We both share the same ...
...thing....
....inside ...
...About led grow light designing and building ...
Cheers.

The steel top & bottom lids are made of 1 mm thick sheet. (19 gauge,I think .. or ~ 3/64" ).what gauge sheet steel you using? smaller gauge tents to bend or buckle. I have a thing for metal work.. but more to do with offroading. welding.. bending tube.. etc.. Fabrication in general is pretty fun. I like watching your light builds. thanks for posting.
The nibbler I got ,cost me ~$45 .
It shears (thickness of sheet ) :
0.6 mm of Stainless / Carbon steel
1,2 mm of Galvanised steel / Zinc / Soft steel
1.5 mm of Copper / Brass
2 mm of Aluminium / ABS / PVC /Dalle Vinyl / Carbon Fiber
2.5 mm of Polycarbonate

holy cow hands of steel using that thing with all the cuts you do. amazing. 19g is pretty thick by hand imo. Your lights come out fantastic. I want t get a metal brake so I can build my own cases in the future.
Ahhh.... If only I had more time. Between work, family, and grow I struggle to complete other projects at times!

Ok ..
I guess I'm pretty strong at least for my height & weight ..
(Nasty job ,you see.... Lot's of heavy weight lifting & carrying around for more than 12 hours per day ...)
Still my arms & hands are in a bit of pain ,after using this tool ..
But the job is amazing ...
Anyway ....
Thickness ...

Nope ..
No bending,whatsoever..
Even if shearing narrow steel areas
(always bend them ,before...In the venting area ..)
Cheers.
