This can be found in Rashi, Onkelos, and Ibn Ezra. To cite a post about this on Balashon: The word tzohar (or tsohar) appears only here in the Tanach and there are a number of explanations for the meaning: window (Onkelos, Rashi, Ibn Ezra) - based on tsohorayim צהרים - noon. The light of noon is compared to the light entering the ark via the window. ...
Either A) Get a pair of timers for the lamps OR B) Switch both lamps on before Shabbos and leave them on all Shabbos. Just point only one at the snake at a time.
Rav Moshe Mintz, a posek in Ner Israel, told me that you can ideally use any light that can be focused in one area (as opposed to the sunlight or the main light in a room, which lights up the entire room), as the purpose of the candle at night is to contrast with the dark in the rest of the room.
In Shmirat Shabbat K'Hilchato in 13:32 he discusses using a dimmer - and permits it, though he recommends covering/taping up the switch. In the footnote (112) he says that since light bulbs do not flicker, there's no issue with "fixing the wick". He has some sources there which I did not follow up on. It would seem that he would not allow the use of ...
The relevant discussion is in S.A. O.C. 240. The Mechaber seems to forbid without exception (the Taz brings the Arizal that says the same thing). The Ramo allows an indirect light (as in through a sheet or reflected off of a wall), however the Taz and the Shach there both say that in such a circumstance it is limited to the same exception as by day - one has ...
See the Rambam in הלכות איסורי ביאה Ch 21:10 that it's forbidden. However, it would seem, that having the lights on before and after the act would be allowed - along with everything else in 21:9. ט אשתו של אדם, מותרת היא לו; לפיכך כל מה שאדם רוצה לעשות באשתו, עושה--בועל בכל עת שירצה, ומנשק בכל אבר שירצה, ובא עליה בין כדרכה, בין שלא כדרכה, בין דרך אברים. ...
Although it is unlikely given the power of most commonly available lasers, it is possible to damage the klaf using a laser if you had a high powered laser. Some may not like the idea of using a laser since it is moving away from the ancient tradition of using a yad, which is considered to hiddur to the Torah in the same way that all the Torah adornments are ...
You can see a series of commentaries on Bereshit 6:16 here. Some of the more relevant ones include Ibn Ezra צהר. מקום שיכנס ממנו האור והוא מגזרת צהרים. Bereshit Rabba "צֹהַר תַּעֲשֶׂה לַתֵּבָה" ר' חוניה ור' פנחס ר' חנין ור' הושעיא לא מפרשין ר' אבא בר כהנא ורבי לוי מפרשין ר' אבא בר כהנא אמר חלון Rashi (quoting the above midrash) "צהר" ...
Based on my knowledge, I would say that even if you would say that since light bulb filaments get hot, it would only be an issur drabonon. This is because you aren't heating the filament with intent to mold the metal into a shape like a blacksmith rather you are heating the metal filament for light, the case now becomes a מלאכה שאין צריכה לגופה.
Here is an article by Rabbi Michael Broyde & Rabbi Howard Jachter that discusses the entire topic: http://www.daat.ac.il/daat/english/journal/broyde_1.htm (side note regarding heating a bulb before it becomes yad soledes- just because the glass encasing of the bulb isn't yad soledes doesn't establish that the filament itself is not.)
I used the Super Wicks this year, but found that some burned with very little output of light. They would stay lit long after the ones that worked as expected since they were consuming oil at a much slower pace.
