Greetings,
So ill get right down to it.
Why are we as a community not sourcing high Lumen per watt COBS from Manufacturers overseas for a fraction of the cost? Built in newer chip dies?
Over the past week I have been searching for high quality COB Chips made with New Dies not the old cheap $3 COBS you see on Aliexpress.
After a ton of weeding out crap suppliers and speaking to many.
I have come up with 2 options that are very high lumens to rival CXB 3590 at much less.
Option 1: 50W COB 3500K 80CRI
Run at 700mA @ 34.8V = 24.36W. Basically 25W COB.
Thermal Resistance 0.78 C /W
150LW+
120 Degree Viewing Angle
20 * 20mm COB
Cost = 3.10 USD or 4 CAD
Option 2 100W COB 3500K and 4000K and 5000K avalible
Run at 1400mA = about 50W
Thermal Resistance 0.78 C /W
150-160/LW+
120 Degree Viewing Angle
38 * 38 COB
Cost = pending
If run at 700mA I can see around 170 maybe 180/LW.
I have checked over these datasheets and they seem to be using high quality dies.
Ill be getting a few 50W and a few 100W and do some tests, but it seems that we can source good quality COBS with 5 year warranty and all certifications.
Here is what they look like.
Here is NOT WHAT IM TALIING ABOUT
So it seems we as a community can source high lumen and output COBS at a fraction of Cree and Bridgelux Vero price points.
Ill be testing the PAR output of these COBS as well as intensity against CXB 3590 and Vero 29 3500K top BINS.
From what I can tell this seems to be a very good alternative and I see no reason to go Cree other than Branding.
I am aware of china lying about numbers, but this is a very reputable company with very serious datasheets.
Prices are good in bulk and if all is well ill be picking some up in bulk to give to the community for low prices.
These prices make HPS obsolete.
Please no BS comments. I know how to source products and have been doing so for years and am very aware on how to cross check.
Please keep the comments civil.
Trippy.
