PAR16 vs PAR20 Light Bulbs: What is the Difference?

There are so many different light bulbs on the market, it can be hard to know which one is going to provide the right amount of light and which one is going to save you money. We are going to look at two of the parabolic aluminized reflector bulbs or PAR bulbs.

In order to understand a little more about the Par16 and the Par20, we will go over their size, brightness, and power consumption. To start, we will cover the general specifications before looking at one brand for a closer look.

Because they are both Par bulbs, they have the same shape. The first difference is with the size, which is represented by their numbers. The Par16 has a diameter of 1.97 inches and the Par20, 2.6 inches. The Par20 is also slightly longer. Remember this is an average, different brands will have different sizes, but by fractions of an inch and the Par20 will always be larger.

Both the Par16 and the Par20 have an E26 screw-in base. So, in this respect, they are interchangeable. If you have 3” ceiling cans, the Par20 is the best fit because the Par16 might look a little lost. If you have 2” cans, the Par16 is the option.

Another difference is the power. The Par16s normally are around 4W, the same as a 35W incandescent bulb. The brightness of the bulbs is between 300 and 400lm. The Par20 is, on average, a 7W bulb, equivalent to 40W. The lumen is a little higher at between 500 and 700lm. These are narrow beam bulbs, most with a beam angle of 45º.

The Final Verdict

If your decision isn’t based on the size of your fittings, we would choose the Par20. The pack of 6 is only a few dollars cheaper but as the cost of running is the same, it makes more sense to go for the less expensive bulbs. You also have the advantage of the CRI rating.
