Thanks all fine
Placed 12 of them on copper strips in parallel, 3cm apart at 1.08A (90mA each) and the copper strip got quit hot within a minute. After placing them 10cm apart, they stayed cool through out the 30 minute I ran them. Used them to replace half the leds on my torch (right side). Have used about 30 beads and all have worked so far. They can handle 250mA but the get really hot fast. Used aliexpress shipping and arrived just under 3 week to local post office. Recommend seller
