Heat Outdoors Handy Dryers Shadow Industrial

Infrared Heater Types Explained

Our search for the perfect heater has led us to develop several market changing technologies that are copied throughout the industry.  The Shadow Heater was the 1st Low Glare heater in the world and now the brand new Ultra Low Glare is leading the way once again and exclusive to Heat Outdoors.

Lamp Glare is a subject which Heat Outdoors have researched extensively.  The result? Heat Outdoors now exclusively manufacture new quartz halogen lamps - Low Glare and Ultra Low Glare.

As well as offering the industry standard, Gold Lamp, the Heat Outdoors LOW GLARE and Heat Outdoors ULTRA LOW GLARE really push the boundaries in terms of heat and comfort for all of our satisfied customers. Our lamps dramatically reduce visible light output and intensity, and also, as the name suggests, reduces the lamp colour too, so delivering the heat you need, yet all with comfort and style too.

Glare comparison chart


The intensity of heat and light you experience with a gold lamp is common throughout the industry. It is a good choice for basic heaters and 'it does the job', however, the very bright light it emits can seem rather invasive. Gold lamps also tend to make all the surrounding area turn a reddish pink hue.


Developed by Heat Outdoors laboratories in 2011, LOW GLARE offers an 80% reduction in visible light output with almost no reduction in heat output. The light itself that is emitted tends to be redder than the industry standard 'Gold' lamps, however, it is not at all painful or bright even when stared directly into. LOW GLARE lamps will have very little effect on the colour and lighting of surrounding people and objects.


ULTRA LOW GLARE was launched in 2016. It is sued as standard in the Heat Outdoors Shadow range of heaters. With an amazing 90% light reduction, this exclusive Shadow lamp emits such a soft warm natural yellow glow for a comfortable and natural feeling.


ULTRA LOW GLARE PLUS is our lab's latest and the most advanced addition to our range. It is exclusive to Heat Outdoors Shadow II range of heaters. The advantages of choosing ULTRA LOW GLARE PLUS are clear for all to see. With an amazing 94% light reduction, this exclusive Heat Outdoors lamp emits such a soft warm natural yellow glow, makes your outdoor experience more comfortable and natural feeling than ever before.

Heat Outdoors are the leaders in this state of the art technology and the only retailer who design and manufacturer it. One day out competitors will, once again, follow our lead, but in the meantime, Heat Outdoors ULTRA LOW GLARE is the ultimate lamp to choose for overall comfort, warmth and performance.

It looks absolutely incredible from the moment you switch it on.

"We have just installed a couple of Shadow II ULG+ Patio Heaters with remote control for our new covered decking. Living on the side of a Welsh Mountain means the evenings can get very chilly but despite the evening temperature dropping were able to enjoy our first BBQ and eat outdoors. Even on the lowest setting the warmth from the heaters was amazing - and so natural." Hannu Ravenol
