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?
https://cms.cnc-cie.ca/images/documents/CIECNCjoint2015/05_Ohno_CNC_CIE_...

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.

60 leds 15w

It is mass, so, it will be in stock ready to shipping

About 75lm/watt in this bulb (with diffuser)

2200k only cob 6w what was produced specially for me by SEL (Smart Eco Lighting co. ltd.)

Only 12×99mm pcb with 3-12 leds http://sunlikelamp.com/index.php?route=product/product&path=80_106&produ...

I have no spectrometer, but you can find any duv what you want. There’s many reviews of my lamp and leds.

It can be cob sol, cob saw (seoul semiconductor), smd 3030 6v, smd 2835, sunLikePlus, SOL cob without violet, S model with switching

Since the bulbs are being mass produced, can we still request specific combinations of CCT in a single bulb?

What CCT?

I know if it will be 2×4k+1×5k = 4200k and it is good spectrum

All another only with big order

That 4200K option may work. Ideally I’d get as close to 5600k as possible but with lower duv, so I’m curious what something like 2× 5600, 1× 4000 would produce.

It might be a good business move to mix 3000k and 4000k LEDs to create the elusive “true neutral” 3500k bulb. There are a lot of sellers selling 2700/3000/4000/5000k bulbs, but I don’t know of any selling a good 3500k.
I know you are thinking I must be basing this on personal opinion, but the ANSI standard “C78.376-2014” accepts 3500K as the true neutral.

I’ll trade you a 3500k bulb for a spectrometer report of it from my C-800 Wink

Spectrometers may look expensive, but if you get one used, then re-sell it, it’s like a free rental Smile

I can take mixing spectrums from my helper for free =)

But I really do not need it

Oooo, you should make a ~13W BR30 replacement. Would love to see that 3500k combo in our kitchen!

Edit: Added BR30:

Edit: In fact, the BR30 is even more suited to this configuration for LEDs. The A19 and A21 bulbs are designed to be closer to omni-directional, while the BR30 is designed for a 90 degree direction beam.

Edit2: If I could buy BR30 in 3500K SunLike 2835 that put out 1000 lumen for under $35 ea, I would buy 6 right now.

Evanh Smile Thumbs Up

p.s. 5% discount for this man!

SunLike10x v.2 (9.5w) (RIRERA9) also can be 11w if 36 leds

RIRERA11 (can be 9.5w if 18 leds)

I can not find aluminium body BR30 =(

But I can add reflector if COB led(s)

p.s. use optiPNG to lossless optimise size of png files (after that pngOUTwin for additional ~5%)

Thanks Joshk, I use Figma for just about everything that doesn’t need more than 0.1mm precision.

Here’s an (optimized) png of my SORAA VIVID bulb. It’s a bit thicker than normal BR30’s, so I took measurements with calipers in case it helps to find another body that might fit.

SunLike, in a year or two years, with the work you are doing in this area, a company is going to try to buy you out in a way that may well sell you short, or worse maybe just take your work and market with a much larger backing fund.

I do hope you are preparing yourself for this.

By the way, subscribed. Future customer.

It’s close. If there was a way to extend it at the base by 14mm, it’d be about perfect. As is, it looks like it gets thicker too close to the socket.

EDIT: Looks like the max diameter of the recessed fixture is 113mm, so too small for the next size up.

Just use e27-e27 extender

I have these E27-E27 extenders from Amazon. They extend the bulb exactly 32.4mm.

Here are both options. I like the idea of risers best, since that gives us the ability to have the LEDs at the same depth within the fixture as a standard BR30. The overlays do show that it might still have a clearance issue though. I’d have to get a more detailed diagram of the standard BR30 fixture to check that clearance without just trying to screw something in.

The extender solves clearance, but also has the plane of LEDs 15mm further from the socket.

I’m surprised to learn that MASS15D costs more per watt than SunLike10 with SOL unless one buys 20 bulbs or more.
I guess that SunLike10 is not dimmable but I still find it surprising.

you mean 10X model?

eXperimental =)

It was born like cheap model with 6w COB led

With SOL led it costs 19$ (was 18$ first time) — http://sunlikelamp.com/index.php?route=product/product&path=59_98&produc...

Real it is 9.5w and when it is hot it is 9w

review here — https://budgetlightforum.com/node/71636

MASS15D have 60pcs 0.5W SOL2835 leds — http://sunlikelamp.com/index.php?route=product/product&path=80_82&produc...

Yes, really it is about 0.3w (with size of crystals)
