Product Description
A universal type ultraviolet bulb / lamp with 6-7% of the output in the UVB range (mainly around 313nm). Over 90% of the output in the 365-370nm range. Designed for a host of applications, including slow to medium speed UV resin finish curing and horticultural plant stressing (greenhouse vegetables in the nightshade family such as tomatoes and peppers, as well as medicinal cannabis in states where this is legal)

Can be used in a standard 32w F32T8 fixture, 40w, any F40T12 fixture, using the Workhorse 7 ballast (4 lamps at ~45 watts each), the Workhorse 8 ballast (4 lamps at ~40 watts, or 6 lamps at ~34 watts each). Will operate with the SunHorse ballast at 66 watts, but this is 10% out of spec and this will reduce lamp life dramatically.

Cutaway of RUVA UV curing lamp

Built-in reflector - Like most of our lamps, the Universal UV FR32 is a RUVA style lamp, meaning it has a built in reflector. This means you don't have to worry about a reflector system for your applications. Keep in mind that reflectors for visible light are easy, but most of them absorb UVA/B, so the regular reflectors for most fixtures are completely useless for UV. It costs a little more to pour them inside the lamp, but it saves you a lot of hassle and work. The image above is a cutaway, showing how it works. All the light will only go out the front of the lamp; light that tries to go away from your target is reflected back towards the target, before it even leaves the lamp. While polished aluminum can be as high as 50% efficient in reflecting UV, this special coating is 80% effective, so you don't waste any UV and get higher overall output at lower wattages, or just higher output (50%+) at the same wattage.

Horticulture - When used for horticulture, some care must be given as this is a medium strong lamp in the UVB range. Keep in mind, the farther you have this from the plant, the less UV it will get but the larger area it will cover, so if you are wanting to run it 12 hours per day, you would want to have it 6-8 foot from the plants. Of course, this has the advantage of allowing it to cover around 3-5 tomato plants or similar sized plants. You can run it as close as 4 feet away, but you will need to have it on a timer to run less hours. The goal is to create just a tiny bit of damage to the plant to where it is just noticeable, not significant. This will cause the plant to increase flavonoid (resin) production. Typically, the UV lights are used only during the flowering/fruiting portion of the grow cycle, however, some growers have been reported using them 1 month after germination, to inhibit mold and mildew on their plants.

Most people find that a standard 32 watt single bulb fixture (like you can buy at any Lowes or Home Depot) is plenty strong enough, and running it at this moderate output will allow it to last around 6 months or more, for 2 to 3 fruiting cycles. This is cheap, easily serviceable and replaceable, and makes it simple to install in your greenhouse.

You can use any ballast rated for 32-60W as long as it is a rapid start or instant start ballast (no magnetic or choke style ballasts). The best ballast is the WorkHorse 7 ballast in standard mode (lower power) to push 4 lamps, or 4 to 6 lamps with the WorkHorse 8 to run it in standard mode. You can also use them in any F32T8 fixture (32 watts) or F40T12 fixture (40 watts), which are readily available at any hardware store.

Yes, these are used as livestock lamps. One is example uses 8 to 16 of these lamps in standard 2 bulb fixtures, four foot long. You make a "dome" that will cover the pig about a foot away at the end of the wash rack, wash the pig, run them inside the "piggy tanning booth" for 3 to 5 minutes to start out, increasing the time as needed (all pigs are different, just like people, so how much they can handle depends on the breed). You are here, so you have probably heard about using UV lamps for this purpose, and the #1 selling lamp for livestock is the Universal UV. We understand tanning hogs, and nothing makes them prettier than genuine Solacure lamps.

Note: Like all UVA/B lamps, it can cause eye or skin damage over time. Take proper precautions. Sold per bulb.
