How about halogen heaters

Halogen heaters are sealed luminescent heating tubes filled with inert gases of halogen elements. There are white and black tungsten wires in the middle. Halogen heaters are vacuum heating tubes with tungsten wires placed in quartz tubes, and the brightness is relatively bright. Which heating method of the heater is good? Part of the energy is converted into light energy, and part of it is converted into heat energy and released.

Advantages: Halogen heaters have the advantages of high thermal efficiency, non-oxidative heating, and long service life, and some models also have additional functions such as timing, rotation, and humidification. Halogen tube heaters rely on light to dissipate heat. Generally, 2~3 halogen tubes are used as heat sources, and the power consumption is about 900~1200W, which is more suitable for rooms with an area of about 12 square meters. Now some more advanced products have functions such as automatic power off when falling down, automatic head shaking and other functions, and the design is simple and practical.

Disadvantages: Halogen heaters produce strong visible light when heated, so they are not suitable for use in bedrooms; the glass tube in the heater is easy to burst when exposed to cold water during heating, so this type of heater is not suitable for use in the bathroom.
