I will not do 9s model anymore =) It was unique - for rewiev SOLs LEDs from SmartEcoLightning co. (it is with the BEST spectrum in the world, better will be StarLike LEDs, but I didn’t tell you this, it is secret) Better than SOLs can be more cheaper LEDs with the same or better quality, but price of leds is not feeld in final price of my bulbs.
But when I produced this model, it was good idea in my mind: I will do S model (13s) with 4 switches, not 2 like in past, and it will be with resistors on it (ordinary and NTC). Previous idea was to use NTC resistor (because with ordinary it will be too much energy when all curent will go to line with resistor) with 2 switches for 4300-4200k middle mode. With 2 switches it is 3 modes, but with 4 switches and resistors it will be 2 types of leds and 9 modes (not 3) with ~2700-3000-3700-4000-4300-4600-4900-5300-5600k
Now I am waiting for NTC resistors to do model in real.
Adam, I'm really glad to have found you online while searching for the Ultimate LED Bulbs, reached you, and that you put enough confidence in us to send you this nicely quadri-equipped bulb so your offering could be tested. With those results I hope many people will now contact you to get those nice bulbs!
And maukka, once again, thanks to have dropped in this Ultimate Light Bulb Quest willingly, and many many thanks for your amazing work with those thorough reviews!
I am going to have to measure my desk lamp to see if one of these can fit. I am a bit concerned about the size and weight though since it’s on one of those spring tension arms. Super high CRI, nice tint sounds like an ideal light for this type of application.
LOL, you should see the .png a marketing company sent me yesterday. It was 627456 bytes originally, but compressed to just 20467 bytes with optipng. That’s 96.7% smaller.
I have no idea how they managed to bloat the image so much. It was bigger than a completely uncompressed raw version of itself.
Adam, would you be interested in selling us the bulbs as a parts kit?
It would make it possible for us to afford more SunLike bulbs. And that would save you a lot of work.
Looks like ShareX isn’t very optimized. Even Photoshop compresses the same PNGs to about 40% of the size (edit: same as OptiPNG it seems). Will have to add the optimizer to the ShareX workflow, thanks!
Adam, what do you think about SOLs 2835 LEDs?
It gives a better $/Watt ratio (but surely requires more efforts on PCB and assembling) comparing with COBs.
yes, sure, I can. But workers time in the first world counties cost much more than my time. Also I have expiriense with manufacturing bulbs and upgrading led drivers. It will not twise cheaper when it will be kit. I think about 25-30% off only
1st problem (with 3030 TRI-R SunLike too) - it is power. I mean real power. It is lower that in the datasheet. For example, 3030 SunLike is 6v0.15A = 0.9W (max is 0.2A) It is a lie! Real size of crystal is 0.2-0.25w, there is 2 crystals. So, real power of 3030 6v SunLike is 0.4-0.5w.
ok. okay… The same problem with 2835 from RoyRex (SamrtEcoLightning). What the real power? I do not know… Because I do not have it. 2nd problem is… They do not have it in stock. I tried to buy 100-200pcs for test, but no. They do not have it and will not produce with my quantity (samples, I need samples only for first time) 3d problem is… Another format, inpompatible with 3030 SunLike from SeoulSemico. And another - voltage! It is 3v, 3030 SunLike is 6v, 6v is more better fore me. And I have no board for 2835, but for 3030 I already drawed and have maked orders in pcb manufacturer. Here is it:
22x22x1.6mm (300pcs)
12.5x99x1mm (300pcs)
12x99x1.6mm (300pcs)
the last one 7 types for C5W (C10W) and W5W (T10) I have no about 100$ =( Somebody, make order on my web-site :cry:
Finally! Price. Wholesale price for 3030 SunLike is 0.25 $ per 1pcs (if 4000pcs), but I managed to buy it for 0.15 $ (it is some miracle, because I was not going to buy it, because I think that COB much better for me with their huge violet crystals). Wholesale price for 2835 SOLs is 0.1 $ and 0.05 $ if 500000pcs. It is good price, but if 3030 wholesale price is 0.15, it is not so good.
Heck yes, I’ll take that action. The bulb I’m waiting on was $17 before shipping. A 28% savings on the next order would be $12.24 per bulb. That means 7 bulbs for the price of 5.
