Yeah, I read somewhere else about the 561C shortage. Also, it seems 3030's are set to be the new standard. I considered using Q strips (LM301B) for this build, but the F and H series were much better value and a little less fucking around. Thanks for the links.

Hi mate, got a link?

I've got some 600x500x3mm sheet aluminum here and was considering using it, but it's quite heavy - heavier than the u-channel frames (which have less material) - and I was concerned about it trapping heat, unlike the u-channels which allow heat to circulate and escape.

The sheet aluminium has one advantage I can see in that it is a large reflective surface. Also, by tipping it on its side in a vertical style grow, it wouldn't trap any heat, so you might be on to something.

When I spoke to a friend about my new lamp, he asked me if I could make one for him too. He wanted two separate lamps(250w) for more flexibility so we came up with thick aluminum sheets. I'm not sure how the temperatures are going to develop, but if necessary I could stick c-channels on the backside.
On the other hand, the Nextlight lamps do not use c-channels either, so it should work that way.

My frame on the last shot is 600x 1150mm and will cover a 750x 1250mm area.
Yesterday I sawed them, today or tomorrow I drill maybe hundred of holes for screwing and laying the cables. I'll put the drivers in the case in the middle of the backside, together with a Sonoff Dual timer and a UVB tube will be mounted below the case and between the strips. But I still waiting for some parts like the drivers, 4 RopeRatchets and so, so it will take at least 2 or 3 weeks until they get ready.

By the way, it is a pleasure to look at your flowers. The SS is really a gem! Also the indika pheno on the old photo. No wonder she has been leading the indika charts for many years.

You can always drill a little grill in the sheets. It would be lots of work, but it might be a fun job for some of us.

Just something I saw
Might explain why the Chinese guys cant get 561Cs.

Wanted to make folks aware there is a shortage of Smasung LM561C 300k and 3500k diodes towards the future. Only existing supply is available as Samsung is retooling their operations towards the LM301B diode which they are producing at a 25% cost increase $0.06/diode up fro $0.04 but only in 5000k spectrum.​

You can offset price increase by purchasing China mutual funds

I'll need to take a photo of my roots when I've finished this grow to show you what they look like.

Haha - not for me!

Thanks mate. This has very much been a learning curve for me and you guys have been great in offering advice. As I said, I knew nothing about LEDs a few months ago and was very skeptical until I started using them. So far, they have exceeded my expectations . . . though I'll reserve my final judgement for the yield ;)

how about a build thread?

once i can prove my new led strips i will consider adding UVB to that tent also.

nice work

Yes, mate! I will publish one for sure.
But first I want to have all the parts together and shot some good photos. I do not want to open a thread and then break for weeks until it goes further. Would like to offer a guide in one piece or at least completely finished on the first page.
It's easier if you find all the information about the project on one page and do not have to search everything together!

Yes, I've seen your work - it is very professional. That COB light you showed us in the other thread was outstanding.

Much as I'd like to add UV LEDs, I think my next consideration will be a couple of 2' T5 UVA/B reptile lights running down the middle. My only concern is I seem to have too much light in there already, lol!

Oh well, the 2000 or 3000lm more or less does not make a huge difference with over 70.000lm as base light, LOL! And the 2' tubes are luckily available with 14 and 24w.
And with a Sonoff Dual you could run both separately on it's own timer.

Hey PrawnConnery! Wasn't able to participate on the forum for the past month or more or would've been following this thread. Just now seeing it. Glad you did one, you were very helpful to me last grow when things started going sour in the beginning. Thnx for that.
Heading out now but will follow along. Hope all so well!

As an aside, I checked out a Nextlight Mega at my local grow shop and it was hot to the touch on the back side and showed 55C or more with my heat gun on the back. So they don't mind running their fixtures a bit on the warm side, at least by most DIY standards. Just saying.:mrgreen:
