I have finally found a suitable replacement for Yuji’s 5mm warm white LEDs. The LEDs should be suitable for C01 hosts (see Djozz’s interest list). This will arrive soon, and will be put on sale shortly after. Now, I’m planning to make a journey further into an uncharted territory.
I have long dreamt of a 5mm High CRI LED that rivals Nichia GS in terms of output. The same company I bought the LED from offered to R&D this type of LED, provided that I would buy a batch after they completed their experiment.
Here is the requirement I told this manufacturer to experiment on:
Tint: ??? (When they mass produce these, they will most likely divide the tint so I know which one is better than others. I will have to take all of the tints and price it differently.)
Nominal Current: 70ma
Output: 24-30lm (at 70ma) — Although I expect the final product to deliver around 18-24 lm (due to the efficiency cost of 95 CRI)
Lens angle: 60deg
CCT: 4000k (initially, more if initial batch is successful)
I’m not sure if or when this experiment will be completed, but this seems to be the holy grail of the 5mm LEDs if the experiment would be a success, at a reasonable price.
Pricing: I have no idea yet, but it can be fairly pricey. To be honest, this can be priced a bit higher than Nichia GS and the 0.5w LED selling on eBay (because they are basically these plus high CRI). Assuming worst-case scenario that I will tolerate, the my regular selling price will be (excl. shipping):
10 pcs — $9 ($7.7 for each extra 10)
30 pcs — $23 ($6.4 for each extra 10)
100 pcs — $64 ($5.0 for each extra 10)
500 pcs — $250
To sweeten the deal, if you are interested, you can sign up and specify the amount you need. I can offer the special pricing for the participants as below, if there are 1500-3000pcs of interests total or more:
10 pcs — $8 ($6.0 for each extra 10)
30 pcs — $18 ($5.1 for each extra 10)
100 pcs — $51 ($4.0 for each extra 10)
500 pcs — $200
I hope this supplier won’t charge me more than what would result in this speculated worst-case scenario, and if they won’t, I will adjust the price down accordingly. Now, it’s your turn to sign up.
UPDATE: I’ve found a similar product and bought a sample of 1k pcs, check my WTS thread for details.
