Samsung Q strips 3500k now boasts 199 lumens/watt !!Does anybody know a retailer of flexible strips with these SMD 2835? https://www.bridgelux.com/sites/default/files/resource_media/DS74 SMD 2835 0.2W 3V Data sheet Rev C_20170817.pdf
They really got my attantion, but I can find anybody... how hard is it, to solder these smd‘s?
I can find strips with 150lm/w, but 180 sounds awesome!
But the diods have way more power! I designed a setup now, with 1200 smd 2835, running at 95w / 190lm/w. I really prefer these small diodes!Samsung Q strips 3500k now boasts 199 lumens/watt !!
Sorry man to querry you again, I guess it won‘t cost you much time... I tried to follow your advise on building a safe aquarium light with eb strips. Actually I think I will close everthing within a sheet of plexiglas (93% transmission) and a wooden frame, to hold some easy alu construction inside for easy strip exchangement (how much space is needed between plexiglas and the led’s? Possible to let the sheet sit on the connectors?) So it‘s protected from most sides, and top is closed with a plate, 2 fans mounted underneath to suck off warm air. 1x2 ft, 14 eb strips, running @ max. 60W. You advised some cv driver.Hey seshwaan,
I will try my best.
1. Yes, 24v version is max 2,5A
2. No, if you use 5 strips in parallel each strip would get around 500mA. Current is evenly divided thru the number of strips(2,5Av5=0,5A). There is a current poti, which can be used to dimm the strips between 250 and 500mA(50-100%).
At 500mA each strip would probably need 22,5v, so 11,25w per strip, 56,25w net./62,5w total.
3. Look at 2.) The drivers potential will be fully used, around 62,5w at the wall.
4.The voltage poti can be used to limit the max. voltage. If you reduce the vf below 22,5v the current gets also reduced. If you for example reduce to 22,1v, each strip would only get the 350mA in your example.
But I would recommend to set it at least to 23-24vf, because if you switch the strips on at 25° they need up to 23v untill the temps stabilizise.
Dimm the strips only via current poti and let the strips take what they need. The vf poti can stay fully turned open so the stripes can take what they need. In plain language, the vf adapts automatically, as long as you do not regulate it below the min. vf a strip would need(depending on the current, of course).
You can of course use stranded wires, AWG20 for example would work. Twist the wire ends and tin them with a soldering iron or use crimp wire ends. But make sure the diameter is still below AWG18 to fit inside the connectors.
You need only wago's if you have no soldering iron. To connect the drivers AC side you need only a suitable wallplug. For the DC side the + wire would go to the +connector of the first strip. If it fits into the connector there is no need for a Wago. Same goes to the -wire, if it fits, good, if not use a piece of the AWG20 and a Wago or solder it.
Because all MeanWell HLG-xxx-xx A drivers tends to have a bit more juice you can expect ~30w min.(lowest current) - 70w max.(max.current).
Q-series are very efficient, but not as effective as F- series. Funny how led folks still using lumens to measure efficiency of the horticulture set upsSamsung Q strips 3500k now boasts 199 lumens/watt !!

Just because of the numbers, I would always prefer Q over F. My reason: 100 LED‘s @25W, covering 2,5x more space than F series. This allows me to have a more diffuse light. So please tell me more, why F series is better?!
Please define how f series is more effective than new Q series with LM301 diodes ?Q-series are very efficient, but not as effective as F- series. Funny how led folks still using lumens to measure efficiency of the horticulture set ups
Effectiveness and efficiency are 2 different things, ones you grasp it - you will get it.Please define how f series is more effective than new Q series with LM301 diodes ?
Please compare/contrast effectiveness and efficiency.Effectiveness and efficiency are 2 different things, ones you grasp it - you will get it.
How many Q series strips are needed to get to 1000ppfd over 4x4 and how many F series strips can do the same job to deliver the same amount of photons?
You have 10% efficiency gain with lm301, but you have almost twice less chips per strip. Gavita is effective, but not efficient.
LOL, it is actually the best point for the Q series, that you need more, so you have a more uniform light, so more diffused light, so less shadows, more penetration, better heat dissipation. So from my pov, Q strips are better in every point (regardless if it‘s effectiveness or efficency) beside your money (I guess, havn‘t seen any price yet).Effectiveness and efficiency are 2 different things, ones you grasp it - you will get it.

"You need more strips" to accomplish the same output.....? Now it's my turn to LOL...Like

F strip is running with 25w, Q strip with 10w. What do you want compare? Sure you need less F strips, but you won‘t get a better light because of it. You just save money!"You need more strips" to accomplish the same output.....? Now it's my turn to LOL...
Dial the current down on the F-strips to 12.5W and you're at virtually the same efficiency, with similar luminous flux per strip but 80% more emitters. That equals more diffuse light, assuming the same number of strips..F562B vs Q562B (4000K)

Just 2 pages infront a guy is asking to power 5 eb strips with 60w. I will use the same power to light up 14 strips. Expecting, that we will use the same area, who will have the better light, which is more effective, and efficient? Besides a few 100lm I will have more, because of pure efficiency of the led‘s...
Have a look into your wallet, get as many efficient strips as possible, and than run them as soft as needed, to provide a proper ppfd. I think that is actually the way to go for the most efficient light you are looking for!
Samsung offering 0,3w (+200lm) led‘s, while Bridgelux provides us with 0,2w (+180lm) led‘s. Thats why I tend to Bridgelux... Think of a tent which is covered in diods. No need for side lights, when your tent is glowing! The strips now, even the Q strip (because of the 0,3w led‘s) are still too powerful, but there are custom builds possible, to achieve this with bridgelux. I really tink about to learn soldering, or reflow oven, whatever, just to be sure that I dont get jackassed on my way to this cab illumination... how hard can this be?!
Covering a space closely with f strips, even dimmed, will give you too much w/sqft, so too much light, because the led’s are too powerful. Covering the space closely with q strips, and running them soft, will let you achieve a proper ppfd, because the led‘s are seperated more evenly about the whole area.Dial the current down on the F-strips to 12.5W and you're at virtually the same efficiency, with similar luminous flux per strip but 80% more emitters. That equals more diffuse light, assuming the same number of strips..
I am looking forward to this! Really! There are so many possibilities... Like simulating the sun movement during the day in your tent, changing the color specs flawlessly and automaticly, simulating the season change. Never have a problem with burnt leaves, or light bleach, because of this awesome diffused light.Hehe, you should wait a few years and then take a tent which is sewn from flexible OLED covered tent fabrics. No need to buy a separate LED.. Like a real ZunCloak..
Actually yes, but I have the 1ft! 2x 12 strips @100w, and 14 strips @50w running in my cab. So I already know what I am looking for now. The aquarium is 70cm wide and about a ft deep so maximum of 29 strips beside each other. But it‘s a lid, so no airflow, and it has to be affordable, we are talking about algae, not cannabis so I decided to do 14, like every 2nd.I was just checking out the F strips and though I had just discovered something. I guess I'm pretty late to the party. Seem like 5 of them in a 4x4 tent would do nicely. Even better 10 in a 4x8, then you can get a price break. @Serva are you saying you would run 14 eb strips on 60w total? I am currently running a light that is 3x4 with 10 - 4 ft EB strips. I am pushing about 600 watts in the light. It seems to be doing ok. Its about a 15 inches over the tops of the plants and im reading about 650 umols everywhere i put my meter. the outside edges are a little less maybe 550 umols
