Do you have the specific bin of your 2700K and 5000K emitters?
I’m not too knowledgeable regarding the tints but I understand these are a tad bit green but tint mixing would definitely help with that. Could someone more knowledgeable than me pass some judgement?
How do you feel about arranging a group buy for a LT1 replacement emitter mcpcb board? 2700K and 5000K emitters. Maybe 12*2700k and 12*5000K or even 16*2700k+12*5000k since the 5000k are naturally brighter.
We would be able to figure out how many we can put on once we get into the board designing phase.
If this comes to fruition, we’ll have a list of people interested, likely you (since you are experienced ) would design, test, and assemble the boards, and then we would buy them from your shop and install it into our LT1s.
But in TRI-T (3-R) technology (violet crystals) brightest of all CCTs almost the same, so quantity must be 12+12 or 16+16 or etc
But with mixing I have many results with spectrums in my telegram like this:
(Sorry for PPFD, but in PG200N fast results only with it, I will try to cut images some later)
mixing SOL COB in SunLike13SS+ and 14SS (2200-2800-4000-4700-5900k)
my video review (RU)
5600k (in this batch not so good spectrum as in the previous )
1. What do you estimate the final price of an assembled 16+16 2700k/5000k board you want to charge is? We should be able to get at least 50 orders if the price is reasonable. 100+ orders shouldn’t be hard if the price is really good.
2. Is something even warmer like 2000k available?
3. Since it’s just a flat board, is cheaper shipping available? Every dollar counts since the lantern itself was not that expensive. Ultimately this isn’t too much of a problem because shipping here in Canada is cheap. I can even just get a big box of them and send them out for a few dollars a package.
1. What is size of pcb?
I think it will be cost ~0.75-1$ per 1pcs if ordering 100-150pcs with all my specifications (I mean 2mm 2oz 2w lead free ultra white mask)
I will take 1.5$ for soldering, you can check it here
But yes, it is with my leds with my retail price
2. No, smd 2000 1800 2250k is not possible. I placed special order to SmartEcoLighting to 2000(1000)pcs 6w 2250k COB leds. Also duv will be too negative (you can find it in the result of mixing 2250k+5600k)
So, best choice will be 2700+5000k or 3000+5000k or 3200+5000k or +4000k
Oh… to much options… But I can solder all of them
3. Shipping from Belarus by tracking small packets same cheap like from China
4$ for 60g

The Bedtime Bulb had issues. Second, I don’t feel the spectrum of that lamp is really world leading, or something that’s really worthy of an international standard. The overlay of of an incandescent lamp in figure 3 shows the Sunlike as being on par to slightly worse in terms of blue. I want better then stock incandescent. I also want warm light that looks like a flame or a dimmed incandescent. 2700K dimmed is not warm enough for me.
