100% legit.... if you wanna go even cheaper. He has eb series strips on sale. 2.82 for 1 footer. 5 bucks and change for 560mm I'm buying some to swap out my veg light. Arrow and digikey are both more on the bridgelux eb series.

And I'm pretty sure the 700mA max on the EB gen 2s isnt max. You can put 1000mA on them on a heatsink and push 23.3w per strip. Maybe even more. Site says 2x overdrive capability. And ledgardner says the max on the 280mm CSN handle 1400mA and 2400mA on the 560, and 1120mm lengths. That means the 2 footers can put out 57.6w @24vdc and 2400mA per strip. Although I'd run em at 23.3 1800mA for 41.94w per strip. On a usaheatsink


Edit: the only downside from cutter he uses DHL for shipping. And they suck. And they are outrageous. I was just about to buy 20 strips until the shipping was the same price as the strips. Better off to get them for 5 bucks a piece from arrow. And get free 2 day shipping.

Says here rated current is only 350ma.

And are the 1' strips in the link the 24v versions you talked about?

I know the data sheet says 350mA max is 700mA on the 1 footers. And ledgardner think they are under rated. This is his quote. And I know they will handle 1.0 amp bc I've done it. They barely got warm. With my heatsinking.

His quote below...

After crunching the numbers, it’s clear that 2 families of strips stand out above the others: the Samsung F-Series Gen.3 and the Bridgelux EB Strip Gen.2. Both of these strips pack a lot of diodes per foot and offer near-identical efficiency. While the Samsung LM561C has a higher efficacy on paper (187 lm/w), you’ll notice that in our designs, the EB strips often have a higher efficacy than the F-strips. Interestingly enough, we believe the reason for this is that Bridgelux has underrated their EB Gen.2 strip max current.

If our hunch is correct and Bridgelux is, in fact, running 2835 .2W 3V Gen.2 diodes on these strips, then the 1-footers would have a true max of 1,200mA (not 700mA, as the data sheet says) and the 2-footers and 4-footers would have a true max of 2,400mA (not 1,400mA, as the data sheet says). That being said, if the true max current of these strips is significantly higher than stated, we would actually be running the strips quite soft, and, as a result, they will run at a higher efficacy than the F-series in our designs.

I wouldve ordered 20 more from cutter but I cant pay the same price for shipping as the damn strips are. If mark @welight would use a different shipper other than DHL I would order 20 more from him right now.

anyone buy through cutter? anyone run these? or the cree j series? this will be a whole lot cheaper then the samsung f series i had planned. i know digikey but haven't done any business with cutter so checking if they're legit before dropping loads of cash with them.

Cutter was one of the first few vendors for COBs here, mainly because of GroMau5 and his tutorial vids. Definitely legit.

W sell the Eb strips adn they are good value but you need to remember these are fibreglass boards and once you start cranking the current your going to struggle to get the heat out of the leds, the moment you get into that situation all numbers around their efficacy quickly dissipate, thats why our SSK-1560 Strips are all metal core PCB. Fibreglass is an insulator not a conductor, if you run EB low or to spec you wont have an issue

Yeah I know they are fiberglass. There are several people pushing 1000mA through them without a problem. I run 8 of them with roughly 1022mA per strip without a problem. I was lookn at your ssk strips. Anyway we can work something out with shipping. Shipping to the states is rough. I know you only have so many options. But I'd like to order either the ssks or some more ebs from you or some of both. Of we can work some shipping out.

I have had fleeting notions to actually test one until it cooks. Likely the only thing that has stopped me, is none of the drivers on hand can do that. Best I can do is give them 1400ma, did that enough to know its fine. I only have the 560mm .

Yeah they are way underrated. Theres a guy on here pumping 1250mA through em woth only u channel and a fan blowing on it. Still stays relatively cool.

I'm really liking the ssk 3000k 90cri cree j series he has. I'd like 5 of them to add to my other light I jus built. But I cant pay the 50 bucks shipping. For 45 bucks in strips. I'd take eb strips too. But still shipping from down under to the states is high.

sorry WW
shipping is shipping and dhl is as good or better than most
unless you wanna get a pile done via real ship..then you have more logistics problems

I think you get free international shipping on orders larger than 500 Aus $$.

DHL is horrible. They have more lost packages and damages. They are the worse carrier ever. And no shipping isnt just shipping. Theres no reason shipping should be more than the parts. There are tons of places in EU that offer free shipping to the states. If they were as good or better DHL would be the leader in shipping. They're not.

I have never had a problem with DHL. Shipping is always fast, have ordered from China and get stuff in like 4 days. Might be driver more than service. I live a few hours away from Cincinnati and i think that's one of there mega-hubs.

UPDATE:
Just placed an order for a little over $110 and shipping was like $23 to the States.

Mark from Cutter is just pro.. really! He could kicking more ass in the LED growlight sector than he does actually but I think it's just his own choice and commercial strategy.

Why not just look at the datasheet?
Here's the link from the Cutter page. http://www.bridgelux.com/sites/default/files/resource_media/DS130 EB Series Datasheet Rev A_0.pdf

They can handle rated current with no heat sink. Max is double the rated current. BTW, those are not the Gen-2, but the prior version. A little less efficient, but a good price.

Cutter has good stuff, but shipping is a deal breaker for most of us.

Yeah if you're in the EU cutter is the best supplier hands down.
