maukka, your PNG files is too large. It is easy to do it twice smaller with lossless.

Just use OptiPNG

If you want additional 0-10%, you can use after that PNGoutWIN, but it is really slow

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.

They probably converted it to a raw format to ‘‘enhance’‘ it, not knowing how image compression works.

Like people who convert 160kbps OPUS audio to Youtube back to 320kbps MP3…

Are the high CCTs like 5000 and 5600 pleasing to the eyes?

I don't know, have you looked outside lately?

 That was funny!!!

 

Congratulations for the results, although I'm not surprised. Thumbs Up

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:

22×22×1.6mm (300pcs)

12.5×99×1mm (300pcs)

12×99×1.6mm (300pcs)

the last one 7 types for C5W (C10W) and W5W (T10) I have no about 100$ =( Somebody, make order on my web-site Crying

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.

curtain

applause

thanks for attention!

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.

Well, some very high CRI COBs I’ve been keeping since I’ve been away from my lighting manufacture job.

They failed lumen testing, so was able to get them for very cheap.

What about a dimming option? Vast majority of lights I use in my home have a dimmer switch and I use them frequently. I very much appreciate brightness attenuation.

Hello!

 

 

The image says it all. SunLike, could you please edit your #6 post here and add some spaces to the text chain? Thanks.

I've reported it to sb56637 to see if some improvement can be made to the forum engine, the above problem also occurs with unnecessarily bloated url links in the simple post editor, I think.

I tested how the diffuser effects the light. It’s very neutral and doesn’t result in any meaningful difference. The small change in tint is probably not even visible. It absorbs 8% of the light, which is also likely not visible. Measurements were done integrated after about 30 minutes of warming up.

I see the COB leds can be directly thermal glued to a heatsink and connected, no need for a board.

However, is there any datasheet available somewhere for them?

SunLike wrote:

from Me! 5$ per 6w COB (13.5mm 35v 360mA max)

That COB features 10S arrangement, seems clear (?). So, 2P emitters would work nicely with long lifespan with a single standard ≈300 mA driver.

How about the other COBs?

I knew there was some capacitor swaps and stuff on the driver, but holy hell. I just skimmed through the 1.3 hour video of you doing ONE bulb. You are a madman. I don’t think I want to learn all that to save 28%. I’ll just settle for affording fewer bulbs.

15-20 hours and 3 days to draw THIS W5W

+split project to 6 pcb boards and convert it to the gerber format
+ stencil
+ postage and etc

yes, I am some kind of crazy

also I have another projects:
“free home in dome”,
industrial leophilizer with small size,

Another thought:
I really like that bulbs. I would like to stock them up for various uses. But for quite a few uses they would be better if they focused on efficiency more than CRI
F.e I just did a quick look at datasheets of CRI97 Bridgelux COBs (BXRE-40H6500-D-73 just to have a reference point). I have no idea if that’s the best out there, it may be but it’s literally the first that I checked. It can do 124 lm/W at 50W and about 150 lm/W at 24W. That’s way more than SAWS1566A which does 93 lm/W at 50W…and for me it would be way better in many uses.

there is one think about lumen per watt.

it is bullshit!

For example, I bought led lamps GX53 with aluminium body do to it with SunLike leds.

MORE PHOTOS

It was about 8w. There was about 70-80CRI 4000k.
I compare it with upgraded to SunLike 6w.

Almost twise (~1.8 time) more lux. But! But body was much more hot than 6w with SunLike. It mean, that real effectivity was the same.

It is not corect to compare lux\lumen, because it is brightnest for eyes, not real efficiency.

In another leds there is no violet spectrum. But it is really important, but for luxmeter it is not so much value.

Also there is 123lm per 1w in new smd 3030 6v SunLike, but it is with pure power to led.

3030 0.2w Samsung 301b have 230lm per 1w, but their spectrum will kill your eyes.

Also it easy to do it more brightnest and effective – add leds with the same power of the bulb.

I see. You’re not interested. I still am.
No, CRI70 doesn’t kill my eyes. I’m not sure if the flashlight I received recently even gets 70. Yes, I would like it to be better but no, I wouldn’t be happy to halve the output for the sake of superb spectrum.

It all depends on use.
In bathroom / kitchen I’d like the highest CRI I could get.
In most other rooms CRI97 is good enough even with dips in the spectrum. In general I would prefer more but now price becomes an important factor.
In more portable cases (desk lamp f.e.) wattage becomes a limit. Get a bit worse spectrum for 50% higher peak output?….for most uses even SOL would be powerful enough but I would be happy to support the rare cases when I want to use the lamp as a moving head. Evil
