The LED took 27 days to deliver, which is not bad at all if you have no need for it instantly.
It came in a plastic bag, put in plastic-bubble protected letter.
The LED is perfectly functioning, the "warm white" description fits well as it is perfectly balanced.
It was soldered correctly, but the plate gets a bit hot. I recommend attaching a heatsink, just to prevent overheating.
I am very satisfied, if you try to buy such LEDs in Italy, they cost 6€ to 9€, which is a real theft.
Perfect quality for such a cheap price!

If you want to power it with 5 Volts, I recommend using a 3 Ohms power resistor in series to the LED. This will limit the current to 0.78 A and the voltage of the LED to 3,73Volts, which is very close to nominal values. I still recommend to attach a heatsink!

very good product, strong light, 2 pcs light more than 9W energy-saving bulb (on the picture right is LED), 7 pcs with 20W switched constant current driver light like zhe "sun"! Inly one of ca. 20 ordered pcs was reverse soldered to alu-plate (plus on minus and minus on plus) but I always try the functionality of each LED so never mind...

Ordered 10. Got all them separately packed .
All 6 what i tried worked. Other 4 are still waiting their time.
Changed 60W bulb with 3 of them, got little less light and they are little pit blueish.

Specifications: Not very warm, i got little blue in them.
When I ordered then in item specifications where 6000-6500k (so i think that i got what i ordered)
Tried with 0.3A, 0.5A and 0.6A
With 0.3A didn't got much light out of them,
With 0.5 and 0.6 didn't see difference, they where both bright.

Overall:
Good LEDs with good price

Great product, I waited a long time for delivery, but it was worth it, great quality, thanks

Powerfull ! You can light all the living room with 3 of them !

I recommend this product, all too good price quality ratio.

товар прибыл но ещё не опробован.

При определенных действиях по монтажу получается хорошая бюджетная штучка
