Nichia NF2W757GR-V3 [GRV3] Flashlight Modding and DIY Parts

Nichia sent me hundreds of several different LED types for my past city garden light project prototyping. I found some very interesting “BLF-worthy” LEDs. One of them is currently the only medium power Nichia LED which is OEM rated up to 2,4 watt/LED. For 3030 medium power LED, it’s like an XHP50 to XML. It’s Nichia’s most powerful medium power LED. There are two variants available: NF2W757G-V3 (3V) and NF2W757GR-V3 (6V) I’m only interested in NF2W757G*R*-V3 (GRV3) because it’s OEM rated up to …

100+ watt LED wattage

Is there any way to have two isolated sets of LED’s on one board? I would like to have adjustible color temperature, so have alternating rows of 5000k LED’s and alternating rows of 3000k LED’s, where all the 5000k can be controlled separately from the 3000k.

No by default. But you probably can do it yourself by scraping the masking and make your own wiring path.

Hello clemence !

Any plans to bring such packages (more particularily the Optisolis based ones, as tested bu Maukka) in a complete bulb format (E27 based for instance)?

Yeah, I’m thinking to make circular DIY kit for light bulb retrofit. But the problem is in choosing universal sizing for the MCPCB. Would you like to participate in the research?
And one more thing: almost all light bulb’s diffuser are glued to the base. Not so easy to open for general public

At the moment I can't think of a better dream solution than using R95 Optisolis to light my rooms. It's your fault, since you made me discover Jetµsolis!

So, you bet I'd be glad to help to find a solution to mod/create our own bulbs!

I know we have Bocian here that is creating some nice custom E27 bulbs, based on Citizen LEDs. He might be of help. Maybe by joining each of our BLF's talent we can build together the ultimate bulb.

I like the sounds: Ultimate bulbs. I’ll try to contact Bocian then. ….or any other light bulb manufacturers

Because of the nature of things, safety reasons and the manufacturer’s policy, LED bulbs are not intended to be opened and modified. There will be someone who does not know the basics of electrical rules and we have an electric shock and other problems

I wish you luck with this too. The first question will be how many thousands of pieces you want to order in this configuration

Clemence. send me PM about what You want to achieve/produce/sell. What materials, shape, mounts, expected power, way of light distribution (diffuser/reflector/TIR), electrical parameters (current, voltage, power) of Your LED module.

Hi Bocian,

Thanks for your response. This is not about me. I personally have an agenda for another project. So, I’m not going to be the person in charge for this one. Optisolis light bulb is indeed something I have in mind since last year. But at this point I can only provide special custom designed MCPCB and Optisolis LED. Since you already have some ready to use product, swapping an LED module should be easy. Your product use 36V Citizen, right? And being a light bulb, no specific optic is required, just an unidirectional diffuser bulb is needed.
In my opinion Fneuf should be person to arrange another BLF project for BLF ultimate light bulb project. He has done some researches deeper than most of us in this topic. Just like many BLF projects before, this could be a great pilot project for another greater ideas.

Bocian · 2019-11-04T15:57:36.000Z

Yes, I use mostly Citizen CitiLED 12s (~36v) 97 CRI. Some sample photos with E27 base:
5W/7,5W/9W, incandescent 75W:

9W, 12W:

18W:

Centrally embedded COB diode is located on the copper plate, but there is no problem to use other LED module (with a properly selected power supply, of course).

maukka · 2019-11-04T16:02:25.000Z

If an Optisolis E27 LED bulb ever comes to fruition, I’m up for at least 20.

Bocian · 2019-11-04T16:25:02.000Z

Here is an example of ceiling lighting:

Sorry if I make a mess in Your thread Clemence.

clemence · 2019-11-04T16:29:00.000Z

No worries Bocian, it’s related. You can PM me the available space for the Optisolis board. Can you make the driver switch modes by tapping the input? Phillips use this method to switch between CW, NW, and WW. This way I can design a multi CCT copper board

I'd be glad to help with my modest abilities. Like seriously I'm not the perfect technical guy for that (I consider myself way less proficient than you guys), but at least I'm motivated and I'm pushing this idea. So I can still help, coordonate, and maybe handle other aspects: like putting a toe in the water and see if we gather some feedbacks of the crowd.

But before reaching that, we need to make it serious. Which competencies do we need, what specs are we targetting, what is the public for that, etc

The thread I initially created around this topic "LED Bulbs - Ultra High CRI - The Honorable Quest" has reached more than 1400 view in less than 3 days. I don't know the average metrics for topics on BLF, so at the moment I don't know if it is a clue of high interest or not. But let's see that.

I propose, not to interefer more with Clemence mPCB current offering, that we all continue this specific discussion in the renamed:

>> "Ultimate LED Bulbs - Ultra High CRI - The Honorable Quest" <<

And keep the discussion here exclusively about clemence mPCBs.

I would like to make a mule out of this board, but as is it requires a pretty big head. So I wonder if it can be trimmed at all? The intended led config is 36p.

Also I wonder if anyone is aware of a soda can sized flashlight with a tilting head, which can accommodate this board as is? the driver has to be capable of at least 10amps @ 3.7v
