I asked the manufacturer about the tint control. They said that they might not be able to control the tints well enough and can only guarantee <6 SDCM color matching.
6 SDCM technically confines within A4/A5 bin, but that itself is a rather large area so some of you might actually get fairly yellow ones. I asked them if they can group them, which they could. However, I must pay the labeling cost.
The binning will separate the LEDs with <4.5 SDCM from the ones outside. This extra label cost itself is pretty substantial and will render partnership with BSM no longer financially viable for either party, if I keep the price of the “best bin” at $11-$12
If I go through the binning process and sell this myself. I will send the better binned LEDs to the participants and may perhaps sell the rest for the cheaper price of $8.0 - 8.5 to cut loss.
I want to hear your thoughts on this. Whether 6 SDCM is acceptable for you or should I go through the binning process.
If you’re willing to bin them and still sell them at $12 each, I can’t think of any downside for us. I would gladly pay less to get the “reject” binned LEDs, so others can get the better binned ones at “regular” price.
The only downside is that I will need some people to buy off the rejects too or I lose money. Once binning is complete, I estimated there will be 20–40 rejects.
I want some reassurance that the rejects will sell at around $8.5.
I now created a list for people who are interested for a discount. If you are lucky, you will just get one with CCT shift and only mild tint shift.
Well, since I was going to spend $36 anyway for three of unknown bin originally, then I would be willing to get five of the rejects at $8.50 each for $42.50 at the discount rate if it happens. If you happen to get only 20% rejects, then my five would account for 20 of the better bin. If you can just get a couple more people to do that, you could still proceed with the purchase/sale right?
EDIT: To clarify, I mean to say that I will still buy three of them if you don’t bin them, and we pay $12 each, or I will buy five of the “rejects” if you do bin them, and I can get them for $8.50 each.
Still in for 1x 4000K. Tbh it’s not surprising ordering such a small batch would not get you exact binning. I would just randomly ship them and charge everyone the same with the expectation it may not be exact tint but within a range. CRI should be consistent.
Next time just under promise from the start and over deliver
In any case, I will leave this on about 1-2 weeks before round up and order the 4000k (if it hits the threshold, that is). We’re back to the original deal where I promised the tint will land somewhere on the A4 bin.
I will work on 5mm leds in the meantime.
Edit: since Shirnask has dialed back the order amount, I guess we will have to wait.
I’m not sure if it will prove to be profitable for you in the end, but I sure appreciate your efforts getting chinese manufacturers make special high CRI leds and resell them on BLF. It is something that not many have a talent for, or the endurance to try or have the willingness to take the risks.
To be fair, I still haven’t got to breakeven point for the previous COB purchases. I will need to be rather conservative when it comes to committing the order.
I’m still awaiting the total amount to hit the minimum amount.
Since I haven’t yet fully recovered from the COB purchase (the first WTS from me if you recall it), I still need to be more careful with my investment.
I’m planning to buy an A4 bin for real pretty soon, preferably before the factory closes during new year and Chinese new year.
However, due higher MOQ than planned, I will very much prefer the interest list number to hit 50 pcs before doing so. Otherwise, I will take a fairly big financial hit.
