You can get the almost identical 1st gen models for $11 at verical instead of mouser. Also, the strips based off of the lm301a chip are even cheaper. lots of info here: http://rollitup.org/t/samsung-hard-strips.908616/

added 2nd strip. this time I used the HLG-185h-48A to drive 2 strips in parallel. I confirmed that the driver can act in CC mode, adjusting voltage as needed (observed as low as 22V). I dialed in the current so that it showed 67W on my killawatt and let it run with 2X strips for 20 minutes...

tested strips datasheet: http://www.samsung.com/global/business/business-images/led/file/product/lighting/201601/Data_Sheet_F562A_Gen2_Rev.1.1.pdf

Yes all of the links in this thread are for strips. data sheet for influx series (I don't have these yet but am pretty confident they will perform very similarly in terms of heat dissipation)...

Ok, let's do some maths.... the 16 strips i referenced were different -- they are influx s02s, each with 24 lm301a (different higher power led), running 12.1V and 16W. I mentioned using 16 in a 4p4s config to fill up the available power from a HLG-185h-48a (185W driver). In this case, you are...

samsung lm561b

A quick update - I'm pleasantly surprised so far. I attached a single 33W strip to a 20x14 baking sheet. I dialed in voltage/amperage on a dc-dc buck to get 34W at the wall, let it run for 10 minutes, took temperature readings on black tape on the rear side of the sheet. Ambient was 76F...

which product? NM - the old BML product line used osrams. Not sure about the new ones.

I'd like to see the mini 150 come down to about $300. That would put it more inline with the some of the other commercial offerings out there.

@robincnn uses 48V laptop power supplies (constant voltage ac/dc adapters). I've always read that is bad due to possibility of thermal runaway, but I guess you can mitigate that by buying a power supply that is not over powered (max output can't damage the lights). He's got more experience in...

I'm not knocking a good product. I'm delighted to see that quality samsung SMDs can grow nice plants and NextLight proved that out. I understand certification costs money and time. I also have an automatic temperature-based fire extinguisher in my cab -- So I guess you can add $50 to the...

My apologies, I guess I should have spelled it out. Someone else PM'd me and had attached 1 L09 to 1 HLG-185H-48A. I believe he inadvertently ran 1 strip @ 4A which isn't advisable (it was a short test I think). I'd run 4X L09 per hlg-185h-48a or 16 (4s4p) of the s02.

there are many times you can make a driver work with some thought. In this case, the driver is 1/3 the price of normal, so I'm willing to put in the extra thought. You are right about current, but it is also adjustable via internal potentiometer down to 2A if needed. In my post, I mentioned 4...

just go to bgmicro.com and search for meanwell - you'll find it. They have 140+ in stock

Still working that out. In the next few days I'm going to screw in 2 of the 33W strips (the initial ones linked in this tread) on an aluminum baking sheet and do some temperature testing. I expect it'll be OK with a slight breeze but I don't know for sure. See Robin's post above - I believe...

where do you get your aluminum plates?

@Chronikool, If you want to build your own nextlight mini 150 type light, check out the pricing above and pair it with one of these: http://www.bgmicro.com/hlg-185h-48a-led-series-power-supply-48v-3-9a-constant-current-high-efficiency-by-meanwell.aspx meanwell hlg-185h-48a for only $23. let's...

based on feedback from the nextlight mini 150W, I'm going to mount some to an aluminum baking sheet and see how they fair. I expect I'll need a light breeze over the top, but that remains to be seen. Somehow, the nextlight appears to only use a PCB (not sure if it's aluminum or copper) and no...

More options available and fantastic price points -- these are using the LM301A (3030 smd) instead of LM561B (5630 smd). influx L09, 48V 1380ma 66W, 130-140 lm/W @Test current depending on CCT, $17.17 minimum order of 2 from verical https://www.verical.com/s/7n90l1ww/ influx S02, 12V 1380ma...

Is the mini150 completely passive -- Does there appear to be a slim heatsink or are they just mounted on a metal PCB?
