no =)
this is the winner in low CCT (2700-2800k) :face_with_monocle:
0.5$ per 1pcs :money_mouth_face:
CRI:99-100 CQS:99-100
But I made glass mated by myself
If add diode (or low voltage) - it will be more low CCT
Now I can only try to use most white cover for led bulb (white milk from Chinese language). But it will be 2500-2600k with 2700k led.
I already contact with SmartEcoLightning co (SOL manufacturer), they say that 2000pcs if I want 2300k. I have no so much money for this =(
They have awesome web-site, but shit product for 20$. I mean that they almost ordinary filament bub is shit. It will work about 1 year, because there is no any cooling system for crystals.
almost 2 years ago I bought from this seller 3 pcs “7w wide” kits. I liked it. Month ago I ordered 120pcs for SunLike ∞ model (8w cheap model for 11€ per 1pcs if ~25pcs - up to 2kg with package), also I designed and ordered 300pcs alluminium pcb boards for this model with 12pcs 3030 TRI-R SunLike (SAW) leds. Actually, it is one place in all internet where I find this led bulb’s bodies.
s. D120mm is more overkill than D95mm led bub body :sunglasses:
It could go up to 2 Watts in that set up and stay cool enough with that heat sink, but the drivers turned out to provide only 450 mA in stead of the promised 600 mA.
But it’s the right amount of light for a bed side light.
I estimate it reaches around 45°C under room temperature conditions.
The little sphere lights up nice and evenly, despite the LED sitting at the bottom.
Light loss due to the white plastic of the spheres is much less than i expected.
To anyone recycling the driver of dimmable E27 LED bulbs BTW:
Just replace the capacitors with higher quality and better rated ones and put a thermal pad on where it can touch the enclosure.
I recently got a few dead bulbs, and got around to removing them, and man, some of those bulbs either use solid aluminium heatsinks with no fins(so much mass though), or pure thermal ceramic for heat transfer.
Only problem? Their caps died.
Other than that, cheap low CRI dead E26/E27 bulbs are good candidates for modding as long as you replace the LEDs and capacitor.
