4 ft 70 w samsung custom aluminum pcb strips

[OLD MOTHER SATIVA]

watts are watts, the strips must still be attached to a heatsink. I have qb's and they need a heat sink too.

if you say so..

but again..so far they appear to not need any extra cooling..when i get them over something i will use the IR gun again

600 w with 15 x 70w strips[1050 w]

there are fans in the room..you'd be surprised how much that helps..

Not really, i have a fan too, but i would hesitate to rely on it, withmy luck the fan would crap out.

If you don't need a heatsink then they're way better than Qb's, I can only relate my experience.

nothing lasts forever, except friendships. When the profits have all been taken all that is left is friendships.

na, you just live from your youtube add revenue, duh!

The hard strips MUST be attached to a heat sink, unless you are planning to put a fan on them or run extremely soft. I am running some now on the Heatsinkusa's 2 inch extrusion and they get warm at 25 watts apiece.

Picks or it didnt happen......
How many are you running on the same piece?

> i am talking about several 20" fans in the room..but again..i will take heat readings when i get them over plants...and as well with no fans

> i reserve the right to be wrong..they "seemed" cool enough when i did the quick par meter numbers

thanks for the input..

I am running my CV strip of 5000k on some flat aluminum material no fans and you can put your hands on the back of the HS and no real heat.

Hello @VegasWinner! I checked your link and it seems to be a good offer.. good link! If I choose the 120 led/meter strip to make a light made with 8 strips of 50cm (60LED*8=480 LED @65mA ~80W)... which driver could you advice to me to run them? I wrote 65mA because it is the value used by Samsung on his site but maybe for a strip it is different... Thank you in advance!

I believe you an run the samsung strips from 350mA to 1050mA. You can use a HLG-120H-C1050A/B for most situations. I have a few of those lying around waiting for a use.

 

[VegasWinner]

Do you know if they also make 2ft. hardstrips or only 5m rolls flex strip?

I am not sure. you can contact Mufue technology Roget and he is a real nice guy and informative too. he answers technical questions fairly.

thank you! how many volts in each 50cm strip of 60 LED?

They are 24v diodes. CC has 70leds/m Cv has 20W/m 5m minimum strip

ok.. lenght is not important..it's always 24V - sry for these noob questions but I know only COBs! I'm not familiar to strips it's a bit new for me!

 

[OLD MOTHER SATIVA]

ok i tested the strip panel

zero fans=from 37c -31c........with one normal cottage 16" fan..they were from 31c -27c

so..strips not hot

on another note,..i dunno if can get more than around 450 umols or whatever those hydrofarm meters are
this is at 8" or so because when i go closer the angle seems to great to pick only single strips
so the cumulative light thing may be important

Could you measure the temperature at the soldering point at the cathode of one of the leds in the middle of the strip?

What were they run at for watts to get this?

Diodes are at 24v and 0.5w 1050mA works for a 1m strip. You could wire up to 8 strips in series and get the desired result. That is my starting point.

 

[OLD MOTHER SATIVA]

600w..

>sure..if i remember next time ..at any rate they run pretty cool

 

[Ryante55]

Have you looked at the luxeon 3535L HE seems like it's comparable to the Samsung

I've had some custom hard strips with the LM561C chips designed and now in production in China. They will be 400 x 30 mm, roughly 16.5" x 1.25". Double rows of 48 diodes, 22-24v at 2 amps max, constant current on rigid aluminum PCBs. A "quantum strip" is the idea. Ordered some samples in the S6 bin 4000K 90 CRI selection, will report back in a couple of weeks after testing, if anyone is interested. If all goes well I expect to have them available also in 3000K and 5000K, and 800mm lengths.

will take a photo today of the new clones and a few tiny seedling under the 15 strip/600 w rig over 4 x 4 ft

the seedlings are very squat ..

next plan is get the light as close as i can..and still keep coverge

then will hookup the flood and drain so they can grow faster..

i am interested to see how this not intense but crazy coverage configuration does..

the strips are so cool and not even close to needing any thing other than air movement
