Thinking about the Samsung H strips a bit more I realized that the better practice would be to wire them in parallel, since the strips themselves are wired in series. Basically, we're building a big COB, with each strip acting as one of the COB's diode strings. So that changes the driver options. (And makes my earlier post moot, please disregard as I can't seem to edit it.)

For the 2 ft/560mm strips (H562), driven at 480 mA at 24vdc, here's what I came up with from Mean Well:

16 strips:
HLG-185H-24

12-13 strips:
HLG-150H-24

10-11 strips:
HLG-120H-24

8 strips:
HLG-100H-24
CLG-100-24
PLN-100-24

7-8 strips:
HLG-80H-24
HLN-80H-24

5-6 strips:
HLG-60H-24
HLN-60H-24
CLG-60-24
PLN-60-24

3-4 strips:
HLG-40H-24
HLN-40H-24

3 strips:
PLN-30-24

As always welcome the group's feedback, always learning...

I hope you understand now why i wanted a second opinion on your earlier recommendation. This place is all about helping each other and sharing knowledge and a i very much appreciate the followup post with different suggestions. I still havent ordered drivers for my samsung H strips and screwing up electrical wiring is something that i dont want to do obviously. Burning down my house or blowing up my lights would suck.

The last thing i want is for anyone to get the opinion of me thats anything less than someone whos looking to help others where i can while getting help on the thing i dont have knowledge about. Hope were all good baud.
 
Hello everyone, I am probably noob and I about to say something very stupid, but why not to consider samsung f-series gen3 instead of h-series?Based on spech, 560mm model are 23v and 1.12A, for 168lm/watt in 3000k....so 26watt for $10.78 (25 or more pieces).Almost twice wattage for same price, with only 10lm/watt less efficiency( around 5.5%, but if you drive at 20watt each, probably efficiecy is the same and you are getting 66% more wattage dissipation).
Am I stupid or wrong?
I don't think you are stupid or wrong, but I'm a noob too, so I am comfortable being stupid or wrong right along with you.

Reading through the data sheets, the F's have more diodes on board than the H's. For example, looking at the single-row, 560mm part in each series, the F56B has (8s x 9p =) 72 diodes. The H56D has (8s x 6p =) 48 diodes. The data sheets don't specify which diodes are used in each strip, but assuming they both use the same 561c, that would explain the greater output of the F's.

Where did you find the pricing of $10.78 (25 or more pieces)?
I have done rapid search and found it on digikey

I tried looking through it but honestly i dont have the base knowledge on this stuff to give a qualified judgement. The way i look at it is any of these mid powered diode strips are going to be great and i'd expect every generation update will improve. Dont expect todays "best" to be next months best. I honestly think you cant go wrong with any of these choices be it bridgelux EB strips, samsung H series or samsung F series.

Thing is samsung themselves advertise the H series as their best high end lighting for efficacy and id trust them to market their best as their best. Hopefully someone who understands this all better can decode the documentation into plain english for the rest of us.

The H series info and data sheets ect

The F series which they advertise as high bay lighting solutions (warehouse lighting)

Okay Pickles, I've finally gotten around to it and I'm sorry it took me this long. Here are the pictures. The Ledil Florence optics will work with the EB strips but not the Samsungs. Also, how the strips are secured will also be the determining factor in using them as you can see the screws get in the way. Securing the optics with clips means you wouldn't be able to run the strips side by side, there would have to be a minimum of 13mm separation. Hope this helps.



Unfortunately the images are no longer available :cry:
Which exactly Florence model did you use???

I want to use eight Bridgelux L0280 EB strips @350mA (3cm space between two strips) in a small paludarium (non-reflecting walls, 40cm x 40cm base, 75cm height) with optics C14454_FLORENCE-1R-O.
I asked Digikey for the compatibility with EB strip, and they redirected me to Klus products... Ledil has not yet replied :?

C14454_FLORENCE-1R-O is compatible with Samsung LT-S282N ( Ledil datasheet source)...
When I compare drawings of Samsung LT-S282N and Bridgelux L0280 EB on datasheets, C14454_FLORENCE-1R-O should be compatible with L0280 EB strips :confused:

That's what the 560mm strips are rated for. 960 mA for the 1120mm/ 4 ft strips. The 2-footers are 12 watt boards.

See the data sheet or below. 1050 mA will smoke those strips without some clever circuit design by folks who like their learnin' and such.... :rolleyes:

Anyone else notice that the efficacy continues to rise through to the maximum voltage? Different than COBs with their mid-current sweet spots.

-b420
Umm when i read that i dont read the same thing you do. They are seperate columns to tell you raw numbers, they arent a ratio to each other.

It says the Min efficacy is 161 lm/w the typical is 179lm/w and the max is 197lm/w.

For voltage it says the MIN is 20.8 the typical is 22.5 and the max is 24.2

What your mistake is thinking that its a ratio chart or something, it doesnt say that at the min voltage of 20.8 it gives the min efficacy. They are two seperate things. Also you read the typical current of 480 to be the max current which is just wrong. That sheet doesnt list the max current and if you look it up for that strip its 1200mA.

Awful glad i didnt just accept your driver advice as correct because it didnt seem correct to me and when i questioned it everyone acted like i was being a dick. It would have made me waste $150.00 but i bet noone is going to apologize for their reaction to me now are they.

Sorry about the pics, I'll try and get them back up. I used these:F14304_FLORENCE-1R-Z90 I bought them from Arrow

I have a couple questions here... Sorry im a cob guy...
I have 2 cob panels and was thinking of adding 2x 2ft strips of these on each panel..
Now,
Does samsung make a 2ft strip? Or only bridgelux?
Do they make these in 90cri?
If i were to mount these directly to my aluminium angle, how hard can i run them?
What driver would i use to run 2x 2ft strips?
Any product numbers?
I would. Ideally like 3000k 90cri
Thanks and sorry for the newbie questions..
Cheers

So, i think this thread has a tremendous amount of great knowledge regarding different stripper options (insert catcalls and throw dolla bills we all love strippers:hump:) but at the same time its difficult to sort through 38 pages of stuff with only a fraction of it being useful.

Yes, the amazing deal thing at arrow we've all been commenting about is the 560mm strips (22 inches for americans) in the samsung H series. I linked it a few times in the last few pages it should be easy to find. Last i checked it was still there, its $9.75 per 2foot strip at arrow but only in 3000k. The other color temps like 4k ect are all still $13+ for the 2foot strips on arrow and on digikey they were like $16. I havent seen them in 90cri i dont think they make them in it. That said the 80cri vs 90cri thing i'm under the impression from more knowledgeable folks has to do with deep reds which you can add with a couple cheap monos. Please correct me if im wrong on that as over the last month ive spent hours and hours learning and reading about all this. Either way the 3k 80cri strips are currently 25% less expensive than any other color option and when you start buying them in amounts of 10+ that $4 a strip adds up quickly.

I was curious about it myself but my thinking was id add in some deep reds later, anyone else have knowledge about this? because mine is more me regurgitating what ive read than actually knowing its correct.

Edit: oh and i saw that growmau5 has a new vid up about light recipies which is basically this subject. I havent had the time to watch it or think about it yet but i think thats pretty much the center of these color spectrum debates.

Ya buddy the 90cri cobs are killing it.. I think those strips are back upto 13$...unfortunately.. Did i see u wrote u found cheap drivers in canada? Do share please..

No i still havent ordered any or even figured out what the best option would be. I asked for help here, got bad advice, questioned that bad advice and got told i was being an asshole because i didnt just trust something that was wrong. I was frustrated and put driver research on the backburner so to speak as some circumstances changed so i wont be starting my next crop to flower until the first week of june. Anyone with input on drivers for these is welcome but im going to take my time on that choice to make sure any advice i get is actually from someone who knows what they are talking about. From the little research i have done tho mouser.ca seems to be the best pricing accross the board for canadians if choosing a meanwell driver.

Again if theres a better place please chime in people.

Edit sorry not mouser.ca its http://ca.mouser.com/ the free shipping anywhere in canada if order is $100+ is what makes them better than most

Damn guess i was right that the $9.75 pricing was a mistake by Arrow, they are now back to $13+ like all the other color temps. My 16 are mid-route being shipped and should arrive monday or tuesday.
https://www.arrow.com/en/products/si-b8v11156hus/samsung-electronics

So glad i didnt hestitate and ordered asap when i saw the price drop, now i wish i had ordered even more than the 16 i got. The order i made thursday came to $210CAD, same order today is $280CAD.

Hello everyone, I am probably noob and I about to say something very stupid, but why not to consider samsung f-series gen3 instead of h-series?Based on spech, 560mm model are 23v and 1.12A, for 168lm/watt in 3000k....so 26watt for $10.78 (25 or more pieces).Almost twice wattage for the same price, with only 10lm/watt less efficiency( around 5.5%, but if you drive at 20watt each, probably efficiency is the same and you are getting 66% more wattage dissipation).
Am I stupid or wrong?
Have any links for prices and or new (one with graphs) datasheet?
If one could get the max rating lm output bin ones you would only need 4 units to equal the 2 COBs I looked at. At the prices you mention, combined with maxwell LPC-100-1050 it is only $115 vs $170 for every 150W segment of the units I priced out this side of the pond. One would also be using 30% less power.

I already linked the datasheet stuff earlier for F series, but here it is again.
http://www.samsung.com/global/business/led/products/led-engine/ambient-light-engine/f-series
theres different tabs there that has everything for all the samsung strip lights, every model, tech specs, data sheets ect. Makes it easy to compare models. The datasheet is in the documentation tab, but poke around every single scrap of info is on that page for all their models in one handy spot.

Oh and one other thing, if you click on the LED component tab thats where you can look at the diode info for the diff diodes like the 561c.
http://www.samsung.com/global/business/led/products/led-component/mid-power/lm561c

For now im burnt out on research mode for this, hopefully someone else picks up where i left off.

Edit: oh and an interesting thing i just noticed on the "variations" tab for the 561c. For 90cri diodes they are only on bin s1 and s2 whereas for 70cri they are all the way up to bin s7. So its likely only a matter of time before you see 90cri doides popping up in higher bins. It also makes me question how legit HLG is being in what they say about bin numbers used in quantum boards because samsung doesnt even make a S6 bin in 90cri yet.

So upon further reflection, given that arrows pricing shot back up id say Bridgelux EB strips are back to beating the samsung H on cost/performance. The F series fits in there somewhere but im not sure where.

Are you factoring in efficiency? i.e. is there a difference in electricity running cost between the two?

I didnt get super technical and do math or anything, just a general opinion that with a 25% increase in build cost to me personally it would seem not the right choice for me if i didnt score the better pricing. What the right choice for me might not be for you. Just offering up my raw opinion after spending easily 20+ hours in the last few weeks researching options and changing my mind 30 times or so. For me i was moving from an outdated HPS with a balast that is near death so a change was needed, any of these options is a drastic reduction in power use for me so i didnt dig too deep into that part of it. All these strips seem pretty damn close in efficacy and how hard you run them in current i think makes a bigger difference than which of the strips themselves. That means if i get a better cost on purchasing i can purchase more strips and run them softer for the same light so the purchase price of the strips in my mind directly relates to the efficacy i would get because of how hard i would end up running them.

I think that came out sounding incredibly confusing but i hope i explained my thought process there. Basically a cheaper strip purchase means i can buy more of them. If i can buy more of them i can run them softer increasing efficacy and that difference seems greater than the maximum potential efficacy of the strip because i will never ever run them so soft as to be able to hit that number.

I hope that makes as much sense as it does in my own head, maybe not.
