Lighting with a Floating Wick

Is there a problem with lighting using a floating wick? I heard it is forbidden.

There is no problem with this, and it is permissible to light them initially, fulfilling the enhancement of lighting with olive oil. Some who are meticulous light the wick for a short time to burn off the wax coating the wick. [Even according to those who are meticulous, the obligation is certainly fulfilled, and the discussion is only about whether there is the advantage and enhancement of lighting with olive oil].

Shulchan Aruch (Orach Chaim, Siman 673, Paragraph 1); Mishnah Berurah (Se'if Katan 2); Azmera Leshimcha Bulletin (Issue 118). The discussion is about lighting with a floating wick coated with wax and placed in oil, where at the time of lighting, the wax is ignited and not the oil. However, in practice, there is no deficiency in enhancement, as the wax coating quickly burns off when lighting, and it is considered lighting with oil. Nevertheless, some who are meticulous prepare and light the wick beforehand for a short time to burn off the wax, and then light with oil immediately at the start of lighting. [In any case, there is an advantage to singeing the wick so that it burns well, see Shulchan Aruch and Rema (Orach Chaim, Siman 264, Paragraph 9); Mishnah Berurah (Se'if Katan 28); however, a wax-coated wick ignites more quickly].
