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

I have all of these!

SOL2835 0.5w Without diffuser:

evanh · 2020-12-03T08:59:13.000Z

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.

Aren’t they just glorious (sorry, chart doesn’t reach warm enough to show 2000K, 2200K, 2000+3000K). [image]

60 leds 15w

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

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

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 2x4k+1x5k = 4200k and it is good spectrum

All another only with big order

evanh · 2020-12-03T19:51:12.000Z

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 2x 5600, 1x 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 still have no spectrometer =(

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

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

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

But I really do not need it

Did this for myself, but thought I’d share it in case the comparison is useful to others:

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.
