Well packaged, received in good condition and excellent delivery time (13 calendar days from order). I just picked these up for experimenting (OK playing!) They are very bright ans I am happy to recommend them.
Cudownie, bardzo jasno
LED COB Lamp. Thought I ordered 1W. Looks like they had sent me 3W. Connected to my Li Ion battery. On load voltage was 3.45v. Current drawn was 1.65 Amps. Too bright.Will use with a series resistor.
Ordered these to see if they were any good, and they are, I ordered Red & Warm White, they arrived safely and upon fitting them into a couple of my LED Lightswich lights (Middle & Right in the below pic), they work perfectly.
Bardzo przydatne światła cob
Ładny i jasny
Poprawna
Bardzo jasny i jest to ładny produkt.
Bardzo dobry i jasny testowałem go z regulowanym formatem tp 3.7v 1A. Działa dobrze, ale potrzebuje rezystora 1α/1w dla wyjścia 2,1w, lub 0,78 α/0,5w dla 3w.
