So I need about 200 strips of the EB GEN 2 (actually 224 to make 8 fixtures @756w) to run @0.7a.
digikey has no stock and lead time is into December. What are other faster options? I checked arrow and future electronics and mouser. Limited scattered stock.
Starting to check Samsung strips now.

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 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.

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

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

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.
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.
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

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.
For the HO strips I want to use 12 strips @ nominal 1.4a and 53 giving fixture 640ish watts and then maybe ability to turn it up if I am comfortable with the air flow in my room I have tons of fans.
I gotta make the fixture foldable so I can get around the lights to water etc. Because my room width is only 10 feet wide.

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.

FYI.
Looks like 200 of these are due any day now.
"On order"...

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.

Try partial searches..

You can order before they arrive.
I pre-ordered a 20pk of 2ft 27k same sitch. Worked out great.
Then trying to find drivers in stock.... Things seem to be flowing better

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.
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 where we are all confused, bc the datasheets say one thing (2.8 max) and the strips themselves say 1.4 max.

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.

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.
this bridgelux pdf is amazing as well thank u for sharing.

Yes. 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.
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.
That being said ill have to check led count/specs to make sure there is no other difference between.. If that is the case you should calculate buying reguluar gen 3 strips and adding a quality heatsink vs the HO with heatsink... Only difference I can think of is a higher quality strip transferring the heat better to the sinks... So if H.O. with sinks can handle 2x power of a regular strip, I would assume a regular strip with sinks can handle 1.5x its rated max. Not sure I would want it running 2x its max as the core of the strip is probably inferior...
On a side note I am high and have had a few drinks. After all the posts I have read this is what makes logical sense to me but i obviously dont have both strips in front of me to confirm. That being said i wish I could put a few bucks towards a pot that runs these kind of tests for us vs all of us figuring it out on our own... way to much money wasted that way..
edited to add "dont have" instead of "have" towards the end

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 build
