Output Comparison
Standard medium wave
ELX Series’ standard medium wave elements produce a soft, orange glow after reaching operating temperature. There is almost no visible light on walls or at the ground level. They typically have around half the wattage output of the other element types. Standard medium wave elements are perfect for restaurant patios and other areas where light is not needed.

High-output medium wave
ELX Series’ high-output medium wave elements produce a mild white light while operating. Light is visible on walls and at the ground level, but is around 30% less bright than a typical short wave element. However, high- output medium wave elements have an output equal to their short wave counterparts, making them the preferred choice for spot heating, outdoor patios, and other applications where more heat is required but the short wave elements’ intense brightness is not.

Clear short wave
ELX Series’ clear short wave elements have a high heat output and produce a bright, white light that is very visible on walls and at ground level. They are commonly used for spot heating, indoor and outdoor commercial applications, valet waiting areas, and other spaces where a lot of visible light is desired in addition to a high heat output.

Ruby short wave
ELX Series’ ruby short wave elements have a glare-reducing ruby glass that produces a visible red light. With their high heat output and high light output, a bright, red light is very noticeable on the walls and ground level. These elements are commonly used in applications that require both heat and visible light, but where glare-reduction is also desired. For installations requiring multiple heaters, ruby elements are typically not advised as their red light can be overwhelming.
