Crowdfunding of mass model of SunLike bulb (TRI-R) updated 02.05.2021

Sorry for pictures mistakes =( I will fix it

Oh yes. Perfect time for my demolished apartment restoration!

Interested!.

PS after work i’ll read everything

FYI, as of this moment, there are 10 pics showing in Firefox, and 33 pics showing in Chrome.

May be vk.com (vkontakte) blocked by firefox? Or you in the Ukraine =)

Some pictures from my site, another from vk, like free pictures hosting

The one I inspected was hosted from userapi.com

Yes, it is from vk com
Like facebook, but with porno =)

That’s an interesting business decision.

This is SPARTA Russia =)

This is super interesting, I’d possibly be interested in purchasing some.

:money_mouth_face: I will have parts after 1 month

Is it the StarLike LEDs that are coming in a few weeks, or any more info that you could share on those? Would like to see if I can incorporate them into plans for upcoming projects.

Starlike still do not ready to mass production, because it is not enough lumen per watt. In finall it must be about 50lm per watt (sunlike is 100)

This is good news and I wish you success :+1:

Note about the heat sink, I think it has too many fins. Heat sinks for natural air convection that I use in amplifiers usually have more space between the fins, like 1cm or 1.5cm which gives good airflow. Having more close spaced fins means less airflow. Good if you have a fan, bad for natural air convection. So maybe you can find a lighter, smaller, cheaper heat sink with less fins that actually performs better.

This one won’t work but it is to give you an idea. It’s only 10mm thick and 70mm diameter, and gets 2.28 °C/W.

Have a nice day!

Yes, I understand that there is radiators for active cooling and passive cooling. But I choose between available parts in the market. May be sometime in future I will print copper radiator with branch shaped fins

I just find PDF file with these studies Error | VK

2835’s should arrive soon, correct? Can’t wait to see the test results on them! Quite a few projects may very well use them!

I ordered it from my warehouse just 1 week ago =( It is in 71kg parcel from China. 20000pcs. About 2-4 weeks and I will have it. And about 7-10 days it will be arrived to Maukka

Understood. Thank you for the update!

So are the 2835 seen as the next version of the 3030? More efficient or even more sunlike of spectrum? Or is it purely the same tech in a slightly different form factor?

3030 is 6v from Seoul Semiconducor (Korea) with TRI-R (violet crystals)
2835 is more cheap, it is with violet crystals, it is from Smart ECO Lighting co. (in China)

I do not think that spectrum will be better that 3030, because it is so good spectrum in 6v 3030 LEDs, that better can be only Sunlight or StarLike LEDs (I will have it after 2 month)

Is there a crowdfunding campaign for these?
