After several tests performed by Maukka and Djozz, long waiting time, and many discussions…. Finally I got some interesting Nichias direct from the factory with selected specifications according to BLF, TLF, and CPF requests.

- Custom 30mm x 30mm x 2mm VirEnce cathode direct thermal path copper MCPCB for use with those NV4×144Ax
I know it’s a too big, too plain, expensive, and thick CDTP MCPCB. Meant for my photo light project, had to fill the minimum order. But, it will fit various optics by simple milling, cutting, drilling, tapping, and some creativity of course. Please note to never drill on the anode copper strip. Use thermal pad with 3W/M.K or higher to make it electrically insulated from the base/heatsink. Or solder it on any copper base for superior heatsinking

- Djozz 16mm custom copper MCPCB Very simple and straightforward application. Perform MUCH better than common aluminum 16mm MCPCB. The dielectric used is excellent Click here for Test Details 
ADDITIONAL INFORMATION: Ra 9050 means minimum CRI is 90 (typical 93) points, with deep red minimum of 50 points. In Nichia case, the 9050 already 10-20% more expensive (depends on LED types). For those don’t really familiar with CCT binning steps, I screen captured Nichia chromaticity diagram to give you the idea. 
LED manufacturers still don’t have full control over the production variations in colour consistency. You can buy for example 5000K LED but ended having 4500K to 5500K variations in a single reel. Or 5000K with pinkish or greenish colour. So they usually use 3, 5, and 7 MacAdams steps to group the LED CCT manufactured. The smaller the number the tighter the CCT adheres to the standardized baselines.
- 3 steps inward is the highly prized LEDs, normally 20-30% more expensive than 5 steps. The choice for single emitter premium light engines (track lights, single emitter flashlights, medical equipment, high end store display lighting, wall wash lights, etc…)
- 5 steps is where most normal production fall into, if they use good control over phosphor mixing technique. This is usually the baseline for LED pricing.
- 7 steps LEDs are the preferred choice for most non colour consistent critical products, because you can always mix and match several CCT to get the average CCTvalue. The price also 20-30% lower compared to 5 steps. For example street lights, photography LED clusters, multi emitters flashlights, etc…
- Beyond 7 steps oval, the products considered to be off the specs too much. Reputable manufacturers usually destroy or recycle them but, some “leaked” or sold as extremely cheap funny coloured LEDs. For example you can find many cool white LED with melon flavours (very greenish white) in Ebay at amazingly ultra low price. But lately, researchers have found greenish cool white is actually very beneficial for grow lights.
