LED Bulb PAR38, PAR30, PAR20

PAR20, PAR30 and PAR38 - As a private individual, you probably haven't come across the terms PAR20, PAR30 or PAR38, and these are primarily lighting terms used in professional lighting, where slightly larger bulbs are typically used than in ordinary lamps. If you have a shop, exhibition, showroom or similar, you probably already have bulbs of one of these types. Traditional bulbs generate large amounts of heat and use a lot of power, but switching to LED can minimise both problems. See the options below.

What do the terms PAR20, PAR 30 and PAR38 mean?

The term "PAR" is an abbreviation for Parabolic Aluminised Reflector, and the subsequent numerical designation indicates the circumference of the bulb. In all cases, therefore, these are relatively large spot lamps, available with different angles of diffusion.


In a professional context, the PAR20 is a relatively small bulb, although slightly larger than the usual household bulbs. The bulb's circumference at its widest point is 20 centimetres if you put a tape measure around it. This gives a diameter of approximately 6.7 cm. The PAR20 is widely used for small lighting applications in shops, at trade fairs and the like.


PAR30 is a medium-sized spotlight bulb for professional use. The circumference at the widest point is 30 cm, giving a diameter of just under 10 cm. The type is commonly used for shop lighting and exhibitions, but is also used a lot in the entertainment industry for music and theatre.


With a circumference of 38 cm, the PAR38 is one of the larger professional spotlights. The diameter at the widest point is just over 12 cm. This bulb type is used quite widely for both shop lighting, showrooms and much more.

Get rid of the heat and huge power consumption

If you are a shop owner, gallery manager or otherwise professionally dependent on good lighting, you probably know all about the problem of massive heat build-up from lighting spot bulbs. Only a small percentage of the power of traditional halogen bulbs is converted into visible light. The majority becomes infrared radiation, which in many cases overheats the room and can even cause additional power to be used for air conditioning and cooling. This is a waste of expensive electricity.

Fortunately, that's an issue that's becoming a thing of the past. With new LED technology, energy can be used much more efficiently, and many shops and other businesses have already replaced their old bulbs with LED. As a starting point, you can expect savings of up to 80% by switching from halogen to LED, even if the light intensity remains constant.

Full replacement with LED is obviously an investment, but it is recouped in a relatively short time if the bulbs are on all day. In addition, it is a "one-off" cost. LED bulbs typically have an operating life of up to 50,000 hours, or 50 times as long as traditional bulbs. If you add up the savings on the ongoing purchase of new bulbs and the time spent on ongoing replacement, the benefits of LED become even clearer.

Available in several colours

Unlike halogen bulbs, LED bulbs are available in both warm white (which is similar to the colour tone of the halogen bulb), neutral white and cool white. In other words, you have more options to tailor the customer experience, and in some cases the new cooler colour tones could give a boost to the optimal presentation.
