You might try looking for some of the battery-operated candles that appear to flicker just like a real candle. Here at the holiday time is a great time to find them on sale.
And if you're trying to substitute something for candle burning magic I would suggest looking into cord magic.
Cord and knot magic is a very old form of folk magic that was often associated with wind/weather magics. In cord magic the spells are simply prepared ahead of time, and then used as needed. Each knot is then untied releasing the power entrapped in the cord over nine consecutive days.
For cord magic you will need a cord that is nine feet long (three times three; the traditional magical number) and is the color appropriate to the magical working. Smaller cords can be 9 inches long if you want something simpler to carry and store.
Because it is a magical tool, no one else should ever use your cord but you. Tie a knot in each end to keep it from unraveling. Consecrate the cord to your purpose when once the cord has been cut and the ends knotted.
The most common use of the cord is as a storage cell" for the power. The first knot is tied at one end, with the words "By knot of one, the spell's begun." At this point, chanting or meditation is appropriate until you feel it is time to tie another knot.
The second knot is tied on the opposite end with the words: "By knot of two, it cometh true". Take "aim" at this time by visualizing your need or desire being fulfilled. As the power builds, more knots are tied until there are nine knots in the cord. (Not counting the ones you tied to keep the ends from unraveling.
Here is the pattern of tying, together with the appropriate words:
By knot of ONE, the spell's begun
By knot of TWO, it cometh true
By knot of THREE, so mote it be
By knot of FOUR, this power I store
By knot of FIVE, the spell's alive
By knot of SIX, this spell I fix
By knot of SEVEN, events I'll leaven
By knot of EIGHT, it will be Fate
By knot of NINE, what's done is mine
At the tying of the last (ninth) knot, all the energy is directed into the cord and its knots, with a final visualization of the object of the work. The power has been raised and is now "stored" in these knots in the cord.
Why would you want to store a spell? For some magic, the time for it to happen is important.
Suppose, for example, that you want something constructive to happen but the most propitious time for it to do so happens to be close to the New Moon. Do you do your constructive magic during the Waxing Moon? No. You do it early on, at the Full Moon, using a cord.
Now the power is there, properly raised, but stored for use.
You have nine knots. Although they are all tied in one ritual, these must be released one at a time - one a day - for nine consecutive days. Release them in the same order in which they were tied, NOT the reverse order.
In other words, on the first day untie the knot that was first tied (to know which end you started with, when making the cord, braid in a small bead at one end and always start with this end); on the second day, the second knot tied; and so on.
In this fashion, the last knot untied, on the ninth day, is the ninth knot that was tied at the climax of the tying ritual - the time of greatest power.
Each day, before you actually untie, do your concentration on what is to happen, visualize and again build power. Then, as you release the knot, release the power.
Cords should be of natural materials, such as wool, the best, or cotton; however, if all you have are synthetic materials it will still work..Remember that the tool is not the Witch. The real power comes from within you.

Cord magic is often overlooked but it is an old and reliable way of doing spellwork. I often recommend it for those who live in places such as a dormitory where they cannot use the more popular and well-known candle magic.
