The United States recalls Chinese-made LED nighttime lights that are prone to overheating and melting

Tack & Hardware (AmerTac) of the United States recalled LED nighttime lights imported from China. The company sold 227,000 plug-in LED lights because of short-circuiting of the lamp body, which is prone to overheating and melting, and has fire and burn hazards.

AmerTac received reports of 25 LED lights emitting, burning, melting, and carbonizing, but as of the date of the recall, no injuries were reported. The American Consumer Product Safety Association and the company urged consumers to stop using the recalled product immediately.

The recalled LED luminaires were sold from March 2009 to October 2010 for about $6. The sales pipeline includes hardware stores, family centers and lighting showrooms.

The current CPSC recalls include AmerTac's three models: Amerelle, Amertac, Everyday Basics. The model number and packaging code are 71190, 327895, and 076092 respectively.

As LCD display in YFJ company that we usually use it to military grade battery ,especially Lithium-ion batteries ,for these battery applications ,we have obvious advantage is that we focus more on shor circuit protection which we follow the US military standard.

Short circuit protection:The following test shall be performed. Charge batteriesas specified in  ; use of 4.6.3 is permitted. Measure and record the OCV. Short each battery across all the positive and negative terminals with a total external resistance not greater than 50 milliohms. After one hour remove the short from across the terminals. Measure and record the OCV. Stabilize batteries at the normal conditions of 4.3.1 for not less than 2 hours. Chargebatteries in accordance with 4.6; use of 4.6.3 is permitted. Stabilize batteries at normal conditions for not less than 2 hours, then discharge the battery in accordance with The battery shall meet the requirements of
