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

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

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?

no =(

For those starlike spectrums, what device is measuring up to 1100nm+?

UPRTek PG200N 350-800nm
LisunGroup LMS-6000S 350-950nm

About discounts for MASS models
It was the reason why I created it
I think maximum discount will be 20-25% (with 6$ international shipping for any order) and will seems like that: 5+pcs = 5% discount; 15+pcs = 10% discount; 30+pcs = 15% discount; 50+pcs = 20% discount; 100+pcs = 25%
Wholesale price will be about 50% (without shipping)

Now all we need is to get those 2835’s in maukka’s hands. Methinks I’ll have a sizeable order to place!

he received parcel today, I hope test results will be soon, but there was also 4 bulbs :face_with_monocle:

Finally!

SunLikeMASS15D
Ø80x144mm 193grams Δ38° E27/26 e14 B22
35$


Wow, they certainly don’t disappoint. Looking forward to the other CCTs!

I have all of these!

SOL2835 0.5w Without diffuser:






Absolutely awesome.

  • So is that 0.5w per LED?
  • Is that wattage what you recommend for the balance of efficiency, longevity, and output?
  • Still at about 70 lumen/watt?
  • Are these 6V like the 3030? EDIT: I see on your site they’re 3.2V
  • Possible to get them in 2200K?
  • Possible to sell this in 5m flexible strips?

Looking forward to picking some of these up!

Looks amazing!

Some people prefer Duv to be right around zero (neutral tint), and others prefer it to be slightly negative (rosy tint), especially for warmer light.

Have you heard of this study?

Is it possible to tune these bulbs to also offer variants with negative Duv, say –0.005 and –0.010? This would lower color accuracy somewhat, but people might like the light more.

Tint mixing neutral light of different color temperatures is one way to do this.
