Panacol-USA offers a comprehensive line of traditional UV lamps ideal for curing adhesives and sealants. These UV gas discharge lamps include spot units, flood lights, and large area curing systems.

Many UV adhesives can be cured with both UV gas discharge lamps and UV LED lamps. Gas discharge lamps possess a broad light spectrum (320-460 nm). Filters for various light spectra are available. This homogenous blend of UV and visible light energy offers many benefits when curing photo-reactive adhesives and coatings. Short UV wavelengths (closest to 320 nm) typically contribute to drier, tack-free surfaces. Visible light energy (in the range of 400-420 nm) can increase the cure speed of adhesives possessing a combination of UV and visible light photoinitiators. Visible light can also penetrate substances that are made with UV inhibitors. All of this can be achieved by using a broad spectrum UV lamp.

Lumens are a measure of brightness. So if you know how many lumens you want, you’ll buy just the right bulb for any spot in your home.

Islightmeasured in wavelengths

The average footcandle level on a square surface is equal to the amount of lumens striking the surface, divided by the area of the surface.

Here’s something to consider. In the past, we bought light bulbs based on how much energy—or how many watts—they use. But today’s energy-saving light bulbs use up to eighty percent less power to give you the same amount of light. So wouldn’t it make more sense to buy light bulbs based on how much light they provide? With lumens, you can do just that.

A footcandle (fc) is the Standard unit of measure for illumination on a surface. It is a lumen of light distributed over a 1-square-foot (0.09-square-meter) area.

Today you’ll see more light bulb options in stores. These bulbs will give you the light you want while saving you energy—and money.

The most common measure of light output (or luminous flux) is the lumen. All lamps are rated in lumens, as shown in the figure below, and every bulb has 3 parameters listed on the package:

With more energy-saving choices appearing on store shelves, including compact fluorescents, or CFLs, light emitting diodes, or LEDs, and energy-saving incandescents, you’ll have more options that save you money.

To help you shop for the light you want, you’ll find an easy-to-read label on light bulb packages. So you’ll have a simple way to see the bulb’s brightness, how much the bulb will cost to operate for a year, and other qualities like light color—from warm yellowish to cool bluish.

When most people buy a light bulb, they look for watts (W). Recall that watt is a unit of power, (i.e., the rate at which energy is consumed from the electricity supplier). It does not say anything about the light.

So when shopping for a new bulb, look for lumens—or how bright the bulb is. Remember, lumens is the new way to shop for light.

Below are links to Honle UV lamps and accessories with UVA spectra. Please contact Panacol-USA for more information about the Honle uv lamps, including pricing and availability. Application Engineering at Panacol-USA provides assistance with adhesive and coating recommendations, and will assist to optimize your UV curing process for maximum productivity and efficiency.

Instead of buying an inefficient sixty-watt bulb, look for an efficient replacement that gives you about eight hundred lumens of light. If you’re replacing a one hundred-watt bulb, look for an energy-saving bulb that gives you about sixteen hundred lumens.

A 40 watt bulb produces about 505 lumens and has a life of about 1,000 hours. When this bulb is used to light a room of 10 x 10 feet, these 505 lumens are distributed over 100 square feet of floor area. What is the illumination?
