Not worth the price, IMO. You generally get about a 10% increase in efficiency when you cut the current by half. So at 700 mA, you'll probably see ~165 L/W or so - probably about 4.5K lumens total. For under $30 you can get four Bridgelux strips with similar efficiency and similar total lumen output (4.9k at 700 mA):https://www.arrow.com/en/products/sl-b8v7n90l1ww/samsung-electronics?utm_source=findchips&utm_medium=aggregator&utm_campaign=arrow_findchips_2017&utm_content=inv_listing
Are these worth the price? Data sheet says 150 lm/w at max current anyone know how many lm/w at 700ma?
I was thinking they would provide better penetration because of more chips in a smaller space. Also you linked the 4k for the bridgelux so that gives it a little edge it seems like the bridgelux is a little less efficient at half the current of the samsung.Not worth the price, IMO.

159 l/w at 700 mA vs 150 l/w at 1350 mA the efficiency is close enough to be a wash. Lumen output is comparable as well with both at 700 mA. Probably a similar number of diodes as well, since the voltage, current and total lumens is so similar. 4000k vs 3000k... To me, 3000K just isn't worth 4 times the price.I was thinking they would provide better penetration because of more chips in a smaller space.

My USD9.12 each is the highest price, how do you figure?Cutter has the highest price I ever saw!

I dont know Newark, but Arrow has free shipping costs.
Maybe I got something wrong, than please unconfuse us!My USD9.12 each is the highest price, how do you figure?
