Not actually drilled for the m5ās yet but Iām trying to get an idea of how it will look.
The potentiometer is to be fitted to the front of the box section somewhere yet to be decided. But thatās why I want a B type driver.
100k ohms resistance potentiometer if youāre using as an external dimmer on a meanwell.
Not a bad price. Stick a watch on that 
With 4 chips in series this will only give me 100.4w before driver loss so it may be worth looking at a 1050b? What you reckon @Albannach.
All I have chip wise here at the moment are 2 royal blues.
Thatās looking dam good bro how many chips do you need cos i have a few here, i could chuck a couple in the post if you want and i could spare a few holders too bro 
I think if your using a blue chip you could maybe have four 2700K chips with the blue in the middle. You could run all 5 at around 35w each so a meanwell HLG-185-C700B would probably be the best option eh. I have a bunch of chips with leads pre-soldered to them. Iām pretty sure there will be four 2700K among them but the leads will need to be de-soldered for the holders you have there. Iāll send them to you if you want them bro and i could also maybe do a mix and match if youād rather have that cos i also have some 3500K also with leads attached.
Since you have the 4 holders fitted and it would be a shame to start moving things around and drilling more holes so how about i send a few of each and you can decide yourself what ones to fit 
Thereās 4 holders on there albannach you been at them cookies again bro 
2x3500ks will do the trick and 2 blues you reckon? Should keep them short enough in there too
But yeah what you said works bro 
Yeh bro those things are dynamite 
anyway i fixed it for ya lol
btw if your going with 2 blue chips iād probably use a couple of 2700K to balance out the spectrum but itās up to you and i can send you a mix
@Albannach Iāve found a few cobs with tails on in my shed. Gonna attempt a desolder on them. And use 2 royal blue cobs. Being as I have them here
Speaking of drivers, will this one work for you?
I picked it up to run 4 qb120ās though changed up the lights a bit so have it just laying around collecting dust
I think that would need to run a cluo58s but it would be a touch overpower for 38s. Makes me sad cos thatās a good driver 
Ahhh ok
Its a great driver though canāt fit 4 boards in the smaller cabinets so itāll just sit til I find a use for it
Just had a play with a filter to make it a bit more spacey.
What were actually looking like. Tested each cob individually with a 50w driver. (Wouldnāt emit enough power to light them all in series) but we know they work. Drilled and tapped the m5ās for the channel and used a 6mm hss bit to make the hole for the potentiometer. Plus another hole just above that for the ānogginā on the pot to stop it freely spinning when trying to adjust. Lifting eye bolts should be here next week. Just a driver and fan and filter to finish.
There is 2 royal blue. 1 x 3500k and 1 x 3000k.
Thatās coming together nicely eh bro. Iād love to see a bunch of those with CLU048ās and wee dome lenses lighting someones commercial grow
@kushyhaze came today and said āhow much do I have to pay you to make me one of thoseā ffs here we go again. 
Itās turning out a lot nicer than I first thought it would tbh bro. Still got another length of the box section too
These deserve a bit of attention cos they could solve a lot of peoples problems with none of the drawbacks of traditional cooltubes. No big light loss through glass with that bit of kit and a single 4" inline blower could cool several of them
Well. Potentially youāre right. Just need to get to testing now lol. But for that we need to get the tardis built think this is gonna fit the bill for lighting and filtration though.
Woke up to a donation off @Esrgood4u this morning the beautiful man. Thatās 2/3rds of the driver paid for. Thank you brother
Your welcome mate. Like I said youāve done plenty to help me out so itās the least I could do. Now get building
Fortunately my child is very much like his mother and loves sleep. So until about 10am I canāt start. I can get some framing done today when they do wake up though 
I could do with a massive dump of timber dropping by my shed lol
wale and bake says
can you do 
anodizing? 
hmmm
and paint the fastenters 
I donāt have the means to anodize here mate. And paint the fastenerās?
