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.
SunLike, there’s one thing you could improve about your store. Provide efficacy numbers.
F.e. with 50W bulb I can choose to have 1 or 2 COBs and you say that the latter is 15% more efficient but costs 32% more. Higher efficiency sounds good but being able to quantify the improvement would be a major factor in making the decision.
