楼主说的是这个测试吗?
8.8 Drop test
8.8.1 A device with a polymeric enclosure shall be subjected to the tests described in Clauses 8.8.2 and 8.8.3.
这个测试是针对塑料外壳测试的,所以结果只看塑料部分有没有破裂导致触电.

按照UL8750条款,lens可以使用玻璃的。
6.3.4 The lens (optic) of an LED package connected in a circuit that represents a risk of electric shock need not be provided within an enclosure if made of:
a) Glass, or
b) A polymeric material that complies with the dielectric voltage withstand test of 8.4 when a
500-V potential is applied between the electrical connections to the LED and the lens surface.
但是我觉得有安全隐患。LED灯泡如果玻璃摔破了仍然是可以使用的,而电源部分不是class 2的,这时就会有触电危险。而传统灯泡玻璃摔破是不能再利用的。
