Bridgelux EB Gen 3 vs Samsung Q strip (lm301b)

[UpstateRecGrower]

Bridgelux 3000k 4' strip at 30 watts 186 lumens per watt $14.81

Samsung 3000k 4' strip at 20 watts 187 lumens per watt $19.59

So the question is why would anyone buy Q strips??? Is there some advantage to the lm301b strips over the bridgelux I am unaware of?

 

[PSUAGRO.]

If the q have a double row option like f, No other advantage that I'm aware of, except availability on the gen 3 2700k/90cri strips? Haven't checked recently

Happy shopping

I haven't seen any 2700k options?

Future Electronics usually stock some BXEB Gen 3 in 90CRI, with a minimum order of 1 tray (20 strips). The linked strips are 560mm with a CCT of 2700K. The 2700K 90CRI 1120mm strips are out of stock.

I'm a fan of those for flower since press release , no experience with them yet. Only grower I know that's using currently is @Rocket Soul

I received my bridgelux 2700k 90cri a couple weeks ago from future electronics and they went out of stock pretty fast after. I looked the other day and I think there getting more next month so I would preorder now.

They have the Gen 2 strips in 3500k for $8.40. They are slightly less efficient @ 178lm/w but are almost half the price.

I’ve got 100 4 footers of those already

We did a few grows were our vesta strips with the same spectrum worked really well, better than samsungs 3000k 80cri. Current grow is the first with the new light, multi strain from seed and the cannopy was wild and uneven. Still no definite response on this one, i think it depends on your preference and weighing the ratio of blue i. Your spectrum against how much heat you can put in your growspace. Blue; heat=stomata opening.

I'm not quite sure what you are saying. with a bluer spectrum you would want more heat?

 

[TintEastwood]

Integrating some of the 2ft 27k 90cri. Doing 4 on each side. 8 total. Replacing 35k 80cri.


4x4
Left side done.


Is 8 enough?
Or should I integrate more of the 27k?

 

[Rocket Soul]

No, the opposite. Transpiration is one of the challenges with led, both blue and more heat will open the stomata increase transpiration. So more blue, and youll need less heat.

I was just taking at look at the Gen 3 slims on Future today. $5.20 for 2700k 90cri 2 footers (but of course a moq of 180). But based on the report that @Rocket Soul shared here > https://www.rollitup.org/t/bridgelux-eb-strips-gen-3.980457/page-7#post-15502216 I really want to test these out.
Rocket I know you said those were annoying to work with, but I was doing some math, and the fact that they are 1/2 as wide as most strips means the cost for sinking would be 1/2 as much. It would also make for a really lightweight fixture. There's a ton of off the shelf led profiles/housings for strips up to 16mm wide, that you can find at any hardware or led shop.

Digikey has 10 of the 80 CRI 3000K for $86. I am going to be talking myself out of buying these all week now.

Unless I can convince 17 other people to split the 180 pack of 90 CRI strips with me

If you recall the report indicates good values at low current. If you have to sink these you might be driving them too hard. Same thing with the reg eb gen3, you should be much over nominal if you want to stay competitive with sammies and nichias. But the slims would be, imho, too flimsy to not mount on heatsinks. Catch 24
I cant remember who or where but im pretty sure there are some reg eb gen3 2700k 90cri for sale somewhere. They would be a better suited

While we are all *patiently* waiting for your garage to cool off was wondering what your thoughts are on when to harvest. How many days from flip do you normally go? The 9 strains I've grown are all done around the 75th day, I think. Tried to buy a mix of mostly indica and mostly sativa seeds...

it looks like the bridgelux gen 3 is more efficient than the samsung tho doesn't it? The data sheet shows the same lumens per watt for both 4' strips but the test on the bridglux is using about 50% more wattage.

I was planning to run them at 1a each. It seems like a good trade between efficiency and output. I'm too chicken to run my strips bare so when I am looking at the cost for aluminum it's literally half the price to build a frame for the slims. don't have any extra grand to spare so its a moot point for now anyway.

definitely agree that regular eb3 90cri for $2 cheaper than the 80cri slims is the better choice.

prices have gotten really expensive by me at least. I can get actual led extrusions + heatsinks from a wholesale place cheaper than I can get aluminum angle. about 1/2 the price. its a lot nicer to work with and more rigid too. not worried about the overall cost really, just making observation that if I used the slims I could offset the cost of more expensive strips by spending less on aluminum.

you need to factor in the diode count aswell. The samsung are more efficient diode per diode, but i think the q series just dont have that many. blux four foot is around twohundred forty.

I understand that, Q strip Samsung are 80 diode. So about a 3rd of the diode count. When I was talking about the efficiencies I guess I should have specified strip vs strip

1190mm EB Slim Gen 3 strips do have 238 diodes.

1120mm EB Gen 3 strips have 224 diodes.
