I think it was OLD MOTHER SATIVA who posted a link to these TCI strips a few months ago. I got some too on 230V AC.

They seem to work great, although it's hard to say anything about their actual efficiency.

The strips are 1.7 inches in width. A little tough to find two inch u channel locally. I found some online that ill have to get this weekend. I need thermal adhesive tape as well.

Use two 3/4 inch channels on each one.

I have not taken any temps yet. They are pretty warm, but not too hot you can't hold on to them. I'd geussimate in the 130F range. That's with very little air flow.

Just dug up the thermistor sensor for my meter. At 80F ambient the u channels read 115-118 degrees.

Im thinking about adding far red chips and supplemental blues. Should I go with 10 each? Skip the blue? Here are the chips I am considering. Thanks for any insight

Don't do it, lol. If you do add monos, get some 660nm strips, supplementing blues is redundant.

Adding UVA to flood the mid day hour. I went with 10ct 365nm, 10ct 380nm, & 10ct 395nm diodes. Chinese unbranded are the only affordable diodes for those purpose. And expensive still..Capture+_2017-07-05-00-34-02.png

And then 10ct Cree Xlamp Photo Red and 10ct Far red. These u purchased from digikey so i purchased the starboard pcb separately off ebay for much less.Capture+_2017-07-05-00-41-35.png Capture+_2017-07-05-00-42-42.png

The plan is to lay 2" u channel and .75" u channel in alternating rows. Like such the x's represent the UVA diodes which will be grouped in 3's to mimic a common point source. since i have 3 wavelengths, each will be present in a group. And the circled dots are the photo and far red diodes. These are going to be in pairs. It seems only logical to group separate wavelengths. Then lastly the LED strips will be in the wider rows in an alternating 3000k and 4000k pattern. Its drawn to scale on my whiteboard.

LPC-100-700 for the uva's driver. The diodes are 3.5v and I have 30ct @ .7A

LPC-20-350 for the far red and HE red. They're .35a 1.9v 20ct

@iHearAll - I bought 10 of these strips a while ago and haven't built anything yet. I've been trying to find specs for the strips to choose a good driver or 2 to run them instead of the skinny things they came with - do you know what the forward V of these things is?

Cheers

the skinny drivers are fine and are actually pretty comparable in efficiency to your typical meanwell. they sit at or above 85% and you can select 4 current options. .335a (45.5v), .39a (46v), .45a (46.5v), and .5 a (47v) options. take your pick how you choose to build if you go for a meanwell driver.CIMG4611.JPG

Thanks for that mate, that makes it easy. Good to hear the drivers are reasonably efficient. I was thinking of getting different drivers to cut down on wiring but maybe I can do a neat enough job mounting these little guys on a board or something.

I'm subbed on this one so interested to see what you end up with.

Thanks, I won't be doing much until the weekend with these. The shop I use is in another town. But the 2" u channel arrived today. That's a plus
