i think @babybud got some of these, he should be able to help.Has anyone hear of these V Series Gen 2 Samsung Strips? I can't seem to find any spectrum graph for them. But the $/Lumen and $/watt seem pretty good on them. And they are in stock. I am looking at the for the 3500K (SI-B8U342B2CUS). Nominal current is 0.7a on these max is 0.9a. The test current/temp is 0.7 @50 degrees so should be ok to go no heat sink right? 32W on a 4 ft strip.

i would also check out the Influx Linear L04 strips such as SL-B8U3N80L1WW (not H Influx, very confusing). they are only a dollar or two more and much better numbers and are 1.4a max. more diodes too I think. arrow has those ones in stock. i scored a bunch for $1.40 when everyone else had grabbed all the F strips and H strips when they went on clearance. i don't think they make 4 footers though so you would have to do 2 footers end to end.
actually the EB3 4 footers 80cri are in stock at Future for cheaper than the Vstrips, and u can purchase singles. I would probably go with these of either of the other 2 options

Trying to hit 600-800w per fixture I got drivers @200w 0.7a. So for strips I've been looking to spend $10 CAD or less per 27W. I like Digi-Key because I email them with a target price and often they surprising come close. The EB Gen 3 come in at $8.29 per 27W if ran at 1.4a the nominal current (2.8a max). I have 100 of these strips already but still waiting to hear from bridgelux if I would need to heatsink and how much of a sink I need.I have a different v series. I just got home and would need a little time to double check all the specs but pretty sure mine are the lm561b+ diodes. What are you planning to pay per strip @MidnightSun72 ? There may be better options

So for EB Gen 2 Digikey has them at $10.66/ 27w but they are out of stock and I would want 226 strips. They are available to order I am just not sure about lead time right now.
Ok well if that's true about my eb gen 3 HO strips then I'll use them sooner than later I'll see if I can find a driver to borrow to test this. And then order more drivers accordingly.Don't quote me on this as I may have to do a little digging but at 1.4a on the 4ft strips you shouldn't need heatsink as its the same as running .7a on the 2ft strips and we have plenty of members running the 2ft strips at .7a without heatsinks. How many strips are you planning to use per fixture, assuming each fixture will be 4x4? Just trying to get an idea of how much each 4x4 will get to insure you wont have to crank up the power halfway through flower or anything
This is not right as far as i can remember. The 4 foot version have higher voltage but same 0.7/1.4 nominal/max.Don't quote me on this as I may have to do a little digging but at 1.4a on the 4ft strips you shouldn't need heatsink as its the same as running .7a on the 2ft strips and we have plenty of members running the 2ft strips at .7a without heatsinks.

FYI.EB3 4 footers 80cri are in stock at Future
I know what you mean.i dont understand why they have 2 different links for the same item, but this one shows 19 in stock right now, no moq.

all good i deleted that one bc I realized I misunderstood your post. you were just pointing out that 200 more are on the way. definitely one of the best deals going right now.I know what you mean.
Try partial searches..

just going off of him stating "The EB Gen 3 come in at $8.29 per 27W if ran at 1.4a the nominal current (2.8a max). ".. but yeah if they are double the voltage and same .7/1.4 then he would need heatsinks to run at 1.4(max)This is not right as far as i can remember. The 4 foot version have higher voltage but same 0.7/1.4 nominal/max.
this is where we are all confused, bc the datasheets say one thing (2.8 max) and the strips themselves say 1.4 max.just going off of him stating "The EB Gen 3 come in at $8.29 per 27W if ran at 1.4a the nominal current (2.8a max). ".. but yeah if they are double the voltage and same .7/1.4 then he would need heatsinks to run at 1.4(max)
Normal EB Gen 3 strips that are 2 ft are 19.1v @ 0.7a with 1.4a maxjust going off of him stating "The EB Gen 3 come in at $8.29 per 27W if ran at 1.4a the nominal current (2.8a max). ".. but yeah if they are double the voltage and same .7/1.4 then he would need heatsinks to run at 1.4(max)
i missed half the updates in this thread didn't realize you got your answers. awesome! if you can run these at 1.4a bare they are pretty sweet.Normal EB Gen 3 strips that are 2 ft are 19.1v @ 0.7a with 1.4a max
Strips in my possession are EB Gen 3 High Output which are 4ft in length and have forward voltage of 38.4 and current of 1.4a nominal with a max of 2.8m current.
So double the voltage and double the current.
Yes. Still don't have the response from bridgelux on that. But hopefully this week.this is where we are all confused, bc the datasheets say one thing (2.8 max) and the strips themselves say 1.4 max.
Id assume the H.O. has a better quality strip, layers, copper, etc... Everyone has said the regular strips felt under rated and could handle more with heatisink, so the H.O should have a better quality strip to handle an increased nominal power without external heatsink. If you want to push them to max then you will need sinks. From what I'm gathering these strips are basically rated at 2x the power of a regular strip so I would be willing to bet that each strip running at nominal power running without sinks would put off similar heat.Normal EB Gen 3 strips that are 2 ft are 19.1v @ 0.7a with 1.4a max

hook it up and test it. Your atmosphere is going to different than bridgelux test environment... Get a infrared thermometer or even most quality electrical tester pens have a temperature sensor on them as well. Check for temperature and stray current at the same time lol... way better than touching a frame that may have a stray current on a diy buildYes. Still don't have the response from bridgelux on that. But hopefully this week.
But really I can solve all this by testing th e strips at various amperage and seeing. But didn't really want to hook everything up if they weren't going to be suitable.
