Top bin COB comparison 2

[JorgeGonzales]

so why is the 1812 skipped over in this thread? Seems like a better bang for your buck than a CXA 3070 and pretty close to a CXB 3590?

I've got 5 coming to test.

I think nobody had them to test, but now Robin is stocking some. I think they look great...going 1212, 1818, 1825 each step up adds 50% more dies. 144> 216> 324, and the prices are basically $12 > $18 > $24.

lotta flavors there. i chose to skip the 1812 in favor of more color options in the 1212 and 1818 series, as i felt the 1212 and the 1818 covered that ground efficiently enough

I was talking about this one that does 50W passively
https://led.cdiweb.com/ProductDetail/MODULEDXTRA9980B-MechaTronix/574061/

but this one does 75W
https://www.cdiweb.com/ProductDetail/MODULEDMEGA134100BHBG-mechatronix/574067/

and 110W
https://led.cdiweb.com/ProductDetail/MODULEDGIGA152150BHBG-MechaTronix/574069/

the giga is a 5 lb beast which would be hard to find an application for outside of a highbay. with its integrated driver mounting and handy hook it would make some badass garage/workshop lighting tho

You made a hefty investment to make Citzens available at all, and make the cost of efficient LED growing lower than ever. A few weeks ago there was jack squat available, now we have $12 cobs in multiple temps that spank the old Vero 29s in efficiency, let alone the 1818 or 1825s. It's fucking great.

A really big thank you to everyone in this thread. Its awesome

loving the looks of the 1212 and the mechatronix 9980B, soon my projected build will be within reach, with one module per sqft, how could that not be sweet.

Yep, just recieved my order today!

Thank You robin and all who provide the great information here. These Citizen COBs are a real boon to those of us on a budget. Yeah, maybe only save $200 but thats enough to make the difference between a wish and building a light!

That is bad ass!!!

WHAT MODEL ARE THESE!?! HOLY SHIT THEY'RE PERFECT. Flat base with actual FINS Instead of pins. I'd have to assume this is THEE best design for diyers.

Yeah those are crap. Sorry.

 

[Airwalker16]

Yeah those are crap. Sorry.

How so? Why?

 

[JorgeGonzales]

How so? Why?

Well I'm not sure why, since I don't design heatsinks, but look at the data sheet. Heavy and unimpressive, unlike the moduled and high bay lines from Mechatronix.

Good stuff:

Well, that one's made by Mechatronix..

 

[CobKits]

yes i did just now

i saw it mentioned here that the bin jumps were just a patch and they had something new on the horizon.

good to see cree keeping up with the joneses (well, the jones are at 500W+ in that LES size but we'll see what they have up their sleeve...)

 

[CobKits]

new crees and veros in early Q4
new citis in 17Q1

celebrity cob deathmatch = we all win

 

[BM9AGS]

Damn. Should be an exciting year. Especially with osrams new horticulture line.

 

[CobKits]

meanwhile DE HPS is still maintaining its 2012 efficiency and pricing
cobs lumen/$ is double what it was 12 mos ago......

https://en.m.wikipedia.org/wiki/Haitz's_law

"It states that every decade, the cost per lumen (unit of useful light emitted) falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20..."

 

[CobKits]

haitz is such a hack
