See questions above. Can one use LED lights for Ner Tamid?

Ohel Yitzchok (4) permits using electrical light for Ner Tamid in Shul, since no specific requirement regarding this light is mentioned. Chelkas Yaakov (1: 154) mentions that it depends on the tradition of the shul. Mishpetei Uziel (O.H. 2: 23) is also lenient. Yerushas Pleita (6) maintains that since it is in memory of the Menorah in the Beis Hamikdash, no electrical light should be used. Following the above, Kochabei Yitzchok (12) recommends to use olive oil. Horav Shlomo Miller’s Shlit’a opinion is that since Ner Tomid is not an obligation, one can use any kind of light including LED as it usual nowadays.
