There's quite a lot of green in those. As a photographer, my brain is happy when it sees high CRI lighting, I get almost depressed when looking at anything below 90. I HATE green and magenta hues. But I agree these are prolly fine for normal people 😂
Nice review, yeah they are bright! The reason for the color accurate leds was not only to illuminate while printing, but a lot of folks also like to make pictures or film their printer ;)
Agreed. While High CRI may not be strictly necessary, it is definitely worth it. My high CRI Daylight on a Stick make the inside of my printer look very bright and clear, especially in pictures. Also I got my Cree LEDs on Digikey and the price difference was laughably small for the fact that you get a nice high CRI compared to something lower than 90.
I used to have addressable RGB LED strips in my printer enclosure (alongside white strips for general illumination) but I never figured out how addressable LEDs could be remotely useful besides turning it into a rave 😹 RGB LEDs can totally be useful for indicating status and such, but that doesn't require controlling the colour of _every LED individually_ - a basic 4-wire RGB LED strip would do just fine and be a lot cheaper. Probably more efficient, too, not having to power a separate IC for each LED. _However,_ WS2812-style addressable RGB LEDs are probably easier to use and/or compatible with more 3D printer mainboards, so I understand using them here. "Dumb" RGB(W) strips require MOSFET control for each colour channel, while addressable strips can just be connected to 5V, GND, and two suitable GPIO with no particular current demands 🤷♀️ But that was never a concern for my printer since it's already a pile of custom electronics - Smoothieboard, Raspberry Pi 3B+, ESP32, at least 3 custom PCBs, and plans for _so much more_ 😹 So I had no problem adding MOSFETs for the RGB channels, while using dozens of addressable LEDs all set to the same colour felt like a waste... :) (Incidentally, you can get WS2812 ICs in SOIC8 packages, so if you wanted the compatibility of WS2812 but with only one colour per strip, you could use a WS2812 IC and 3× N-FETs for R,G,B to drive a whole string of RGB LEDs as if they were a single Neopixel. (Modern, tiny-but-powerful SOT-23 MOSFETs would likely suffice for most purposes.) Doing that probably rarely makes sense, but it's still worth knowing about :))
@Vector 3D are you still working on a V0/V0.1 version of these I would love these for my little guys. I am sure if you build them they will come to purchase.
I see White, I see RGB... What about an RGBW version? You know, for normal lighting but "flash danger danger yellow/orange!" when a problem stopped the print. :)
Well the prusa mk3 Power supply is 24v If i remember correctly, but what you're missing is a suitable header to control them from on the control board. A solvable problem i think, there must be people with LEDs on a mk3
actually you should be able to. It would electrically in series from one to the other using one end of both the sticks. Would be easier to show on a diagram 😅
Interesting, but would not buy it unless it’s from a EU seller and warehouse. Everything from UK is just a pain to import and rarely worth it unfortunately :(

I'd love a smaller one for my Voron V0.1 maybe 6" or 150 mm long.
If you offer black PCB versions and shorter (V0.1) versions I will pick some up.
And RGB would be the cherry on top.
I'll do my best, stay tuned.

looking for v0.1 lights, and this is great. i definitely prefer white but rgbw if not too expensive would also be cool.
Same. Around 160mm?

I'd actually like to see a little longer and an option to be able to mount to a 3030 extrusion
You could add a transistor and use any open pin to control however many leds you want.
@Vector 3D are you still working on a V0/V0.1 version of these I would love these for my little guys. I am sure if you build them they will come to purchase.
Yes, they are on order. Keep eyes on the shop
Can you adjust the width so they would slide inside the std extrusion slots?
I would like programmable leds, so i can display different colours for different states, or even something like a progress bar
This would be so fucking cool to do a progress bar
This is great, are these 2835 SMD LEDs?
My V2.4 is already lit up by now, but offer some RGBW and/or Voron V0 sized versions and I'm on board!
I see White, I see RGB... What about an RGBW version? You know, for normal lighting but "flash danger danger yellow/orange!" when a problem stopped the print. :)
What power supply is it you are using? looks quite nice :)
Voron v.01 RGB would be great, would the current Voron size fit the RatRig 300?
I'm using one on my V-core 3. 270mm long and about 11mm wide so you can work out where it can fit.
I'd love to see one for the mk3s to replace my current not very bright led bar, instead of pwm at 50% would it work with a buck being 12v?
Well the prusa mk3 Power supply is 24v If i remember correctly, but what you're missing is a suitable header to control them from on the control board. A solvable problem i think, there must be people with LEDs on a mk3
Is it possible to hook 2 of them up in series to get 12v for each?
no, both will be at 24V still then
actually you should be able to. It would electrically in series from one to the other using one end of both the sticks. Would be easier to show on a diagram 😅
@@Vector3DP No. That would make a 48V stick.
I use tv backlight leds salvaged from bad tv's i get for free and a wall wart for power.
Super bright rgb sticks would be amazing!
👍🖖
