Bridgelux EB Series Build

[Serva]

I like EB strips more cause I can get a better coverage than Samsung strips. I am just worried I am missing something... Tent will be 1.6ft(deep)*2.3ft(wide)*2.9ft and I am thinking of setup made of:
HLG-120H-20B (10-20v, 6A)
12x 2ft(560mm) eb strips gen2 3500k
Dim down to ±100w
Probably too many strips but I want to drive them soft because flowers will grow close to the light fixture I suppose.
I am also thinking to add some 660nm and 730nm diodes since I am already using them and I like it.

I did never see your grow thread and I have to admit it is really cool how you did setup your grow!

Too many strips isn‘t possible! I just did a panel with 18x 1ft strips (gen1) @30-60w

Good setup, you won't have too many strips. You might consider some vertical strips. I have one 560mm strip hanging by the wire in each corner.

I get nearly everything I build with from arrow....Ive had orders reach my doorstep in less than 24 hours. Order with confidence.

Sweet

I only wish they had the 4 fters in stock

Free shipping is pricless to a guy past canada

How do you mount strips? screws only or with any thermal interface material?
I saw some of you don't even use an heatsink, probably it isn't needed.

 

[Cold$moke]

Im going to use screws and thermal tape havent decided on my heatsinks yet.

I want real ones but they are spendy to ship here

Thermal tape would be easier to manage with I think

reading the thread about eb2 thermals it does seem I could be ok with a fan pointing at the strips and no aluminium profiles to mount the strips on. Like @Serva did. Atm I only have access to alu. square tubes or L shaped cause I would get them already cut at the length I need, I want a better clean job than what I did with my actual cob fixture lol. Using square profiles to attach strips on would be heavy and pricy, probably not necessary cause of the low current.

I used thermal paste (buy a large tube or tub) and screws.
If I was doing 20mm strips I'd buy slide-in LED PCB extrusions.

 

[Cold$moke]

Its the one part of the build i want to cheap out on as an aluminum worker i know i got something lying around lol

But everyone seems to say that regular aluminum is fine since we usually runs fans

 

[ANC]

THose strips are from $1.50 to $5, so no big expense.

 

[Cold$moke]

I do like clean pro looks though
They look nice

as usual the problem is shipping price from china.
They are far more pricey here were I am

 

[ANC]

no man, it should be peanuts if anything. Their government subsidizes lots of shipping.

there are also units ex UK and USA on ebay

 

[Nutria]

any link to some solid core wire from arrow? That site is a mess.

 

[1212ham]

It would probably be easier to get some thermostat wire from a store rather than trying to find it on Arrow.

 

[Nutria]

Let me understand, these wires are made of copper or aluminium?

 

[Nutria]

2ft strips are 560mm exactly? am I right? Just to know if I can fit them in a 2ft (600mm) tent

 

[Buck5050]

yes there exactly 22"

@Serva May I ask you a better photo of your fixture? I am interested on how you secured strips

I have done it diffrent ways... which one do you mean?

I have panels with a wooden frame and panels with alu frames (post #6 of my thread) and air contact. Both just use 2x self-tappers to mount the strips to the frame (left and right).

I used a really thin alu sheet, which was pretty flexible, and mounted the strips with thermal tape on the surface. On the other side of the sheet I mounted small c-channels crosswise (!), so it became a stiff board. https://www.rollitup.org/t/eb-strip-panel.954018/#post-13962519

For my first panel I used c-channels and self-tappers (post #4 of my thread).

From my experience the 1ft strips are always twisted and when you mount them with screws to a channel, they never have good contact. So thermal tape was way better in this case.

But mostly I like alu tubes as frame (post #37 of my thread), self-tappers (which are also hidden in the tubes), and air contact for the strips (50-100% nominal current). Tubes, because I like to hide my wiring. Tubes are easily re-used 1-2 times, when changing your initial design.

If you are looking for a really clean build, you will need either a sheet or some tubes.

I was able to replace these 2x75w fl tubes with 50w EB strips (12x 1ft), because the light spread was way better.

 

[Nutria]

Since I want to drive my strips soft around 500mA I suppose it is not needed to use aluminium profiles as heatsinks.
Because of this I thought to only use x4 L-channels to make the frame. Screws to secure strips.

I love clean builds but using square tubes I would have to find longer screws and drill more holes for the wires but i would still have to keep wagos outside the tube. No?
