I would have recommended match, but I was under the impression he has ‘retired’ from testing emitters. That status might have changed since his last few posts though.
What are the specs for the star and when are you selling it? I have some 20mm copper stars on order, but I could use more from a vendor that isn't so far away.
Me wants, me wants
I Am no expert and don’t have proper equipment but that doesnt make them any less desirable
Fu*k gold and silver, we fancy copper here. LOL
Zebralight confirmed tracking of H502W and SC52W on the way to us. We placed two orders of the SC52W to Zebralight consecutively, one small and one large. The first batch should fulfill the majority of pre-orders from May to a little over the middle of June. The second batch is set to ship out next week per Zebralight correspondence.
All H502W pre-orders have been fulfilled and a healthy stock are ready for shipment now. The majority of SC52W pre-orders have also been fulfilled and we are awaiting the shipment notice (expected this week) from Zebralight for the remainder of our order.
Hey everyone, we're proud to announce our line of copper direct thermal mounted LEDs! We're first starting with the XM-L2 and depending on the popularity, may expand into other selections.
Ready to ship now are 4000K, 5000K, and 6500K XM-L2s, check the links below for more information.
These are CREE XM-L2 LEDs mounted on copper direct thermal boards. The backs are flat without air pockets and nickel plated. Mounted with a pick and place machine for high precision over hand soldering, these boards also contain 3mm screw holes for mounting. This copper direct thermal solution lets you squeeze the most performance out of your XM-L2 due to its superior thermal properties.
Sorry if this has already been addressed, but has the insulative layer on these copper MCPCB’s been eliminated under the emitter thermal pad contact area for direct copper/solder/emitter contact? Some copper boards are still “old-school” in that they still retain the insulative layer between the thermal pad and copper board.
