I want to cut my SF4000 in half

and use half like a SF 2000.
By the time I have my 5x back up and running I'll either use both sides with a bit of space between the two for better coverage or I'll have replaced it entirely.

So what's the best way to cut 22 inches of 1/8 aluminum without damaging the board too much.
I plan on disassembling the entire board for this process.

I used to have a ton of resources for crap like this but everyone has moved or is doing other stuff now.

Cool!. And I see your point in wanting to space them too, It’s funny that there is still such a huge hole in market when it comes to L.E.Ds for 5x5 tents/areas, compared to 4x4’s
It seems that extra foot is worth a grand somehow!.. I dunno…lol

For the next year, at least, I'll be confined to a 2x4. I have the SF4000 and two Viparspectras[xs1000, xs1500]. The original plan is to use the 1500 or both but honestly, I like the buds from under the Spider Farmer waaaay more than the Viparspectras. I think that itteration of the viparspectras leans a lot bluer that the SF and they both flower fine but the plants that got only SF were a lot warmer and fuzzier.

If it’s like a qb, leds fixed on the boards, score it with a sharp tool and snap?
I cut heatsink sheets with a plasma, but don’t think that’s an option?

The actual led's are on a film that is screwed into the board. I'm going to assume there's something between the film and board like a glue or something. If that's the case, it will still cut but with a little more care involved.

Check a local hardware store for 1/16" wide cut off disc's, they go on an angle grinder and make a great, straight cut.

Can you get everything off the heat sink and just be left with the slab?

Edit: just saw you think they might be glued on. I’d see how far you can strip them down and then take it to a machine shop I bet they’d cut that thing in half for you for $40 or less and would do a bangin job compared to buying equipment and having a wing at it yourself. I had a machine shop cut my heat sink for my 2x4 and they did it for $80 including all the holes and the aluminum itself.

If you don't have a jigsaw I'd hire it out. Put some painters tape over the leds to protect them.

How long is the cut?

Something with a carbide blade cuts alum the cleanest...skilsaw, tablesaw, chopbox all make clean cuts. A finer tooth blade is better and blade is set to the minimun depth you need to make the cut. A shot of WD-40 wouldn't hurt as a lubricant.

It's about 25 inches. Seems like a fairly easy cut but I no longer have anything that will make a nice straight, clean cut.

I'll do this probably after a quick scan of local resources that can possibly do this. I think I have a few options but the biggest hurdle will be convincing one of the business' that there's no liability for a bad cut. A lot of places around here won't touch stuff like this unless you know someone that works there.


At the end of the day, if I can't find anyone, I'll build a jig and dremel it part with the carbide blade, I guess.

Don't talk about it, cut that bitch up without thinking about it. Be a MAN!

so it turns out that the guy that used to make the duffel bags for our business also has a machine shop. When I have time later today I'll see how far I can disassemble the light and then I'll contact mr. machine Next Tuesday[only "free" day and I'm busy moving stuff this week].

If he can't/won't do it, I'll attack it with the dremal and a jig.
