Product Description
This handheld light from Way Too Cool is an ultra-portable UltraViolet UV-C light that is used for disinfecting surfaces. This is NOT intended for continuous use, it is intended for intermittent use. There is a thermal switch that will turn off the ballast if it gets too hot. The unit also has a port on the side for an external 8.4 volt, 1,000 milli-amp power supply which can either operate the fixture, or charge the batteries, but not both.
This lamp is a modified version of another product of ours, The Triple Handheld UV light which has a patented design that includes a piece of filtered glass. This version has clear glass for sterilizing equipment and surfaces.
Sterilization
This lamp is currently undergoing testing by an independent laboratory. Way Too Cool has conducted our own testing using the methodology described at the bottom of this page. We took readings from 10 different sterilization lamps at a distance of 1" and 1/2". The average UV output for all 10 fixtures at 1" was 4,000 micro-watts/sq. cm., and the average at 1/2" was 6,800 micro-watts/sq. cm.
How to Use a Dose Table
The ability of Ultraviolet light to kill microorganisms depends on multiple factors, including (but not limited to): the intensity of the UV source, the distance from the source to the microorganism, the exposure time, and the type of microorganism. Based on the UV output of this lamp listed above, you can refer to the following dose tables for an idea of exposure times for various microorganisms.

SAFETY WARNING
Do not expose your skin or eyes to the UV rays emitted from this lamp. Sunburn will result from over-exposure. Due diligence and all normal safety precautions need to be followed at all times. Children should not use this unit unless supervised by an adult. It is recommended that eye protection such as UV blocking safety glasses should be worn as protection against accidental exposure to the eyes. Sun-block, gloves, or protective clothing are also recommended to protect the skin when using the lamp fixture. Do NOT shine the rays from this unit at any eyes or skin. SW & MW (short-wave, UV C & mid-wave UV B) ultraviolet light/radiation causes sunburn. Ultraviolet radiation of all wavelengths may cause damage.Battery and Charging Information
Some of the WTC Dealers offer different options for the batteries and the charger. When purchased directly from WTC, the light comes with two standard capacity protected rechargeable Li-ION batteries, the filter pre-installed and a charger for 2 batteries. Protected batteries are used so that if one battery is dead and the other is fully charged, there will not be high current flows that might overheat the wiring. Using the two standard capacity (1400 mA) Li-ION batteries that are supplied with the light when you buy directly from WTC, the light provides approximately 1.5 hours of use on a charge per set of batteries. With the larger (2500 mA) capacity batteries, runtime is approximately 2.5 hours.
The batteries will arrive partially discharged because of postal regulations and should be charged prior to use. Please be aware that some manufacturers claim that their 18650 batteries are rated for up to 9,900 mAh and that any value over 3,500 mAh should be suspected of exaggerating. The standard capacity batteries supplied by WTC really only have a capacity of about 1,400 mA, although the label says 9,900 mA. True protected 2,500 mA batteries are available from WTC, see above for pricing.
The light comes with a simple-to-use Li-ION smart charger with fold-away US style prongs. While the batteries are charging the LED will be red. When the batteries are fully charged, the LED turns a solid green and the batteries should be removed from the charger. If you have questions about the charger, please contact us with your concerns.
Accessories
Some inexpensive protected batteries (approximately 1,400 mA) are available for $2.00 each, and better 2,500 mA protected batteries are available for $4.50 each. A selfie stick handle is also available to hold the fixture, which gets it closer to the item to be sterilized without the need to bend down or reach over. The unit has a port on the side for an external 8.4 volt, 1,000 milli-amp power supply which can either operate the fixture, or charge the batteries, but not both. This AC power supply may be purchased for a small additional charge.
Warranty
This lamp comes with a limited 1-year warranty, from the date of purchase, to cover the cost of labor and the replacement of defective parts. Customer is responsible to ship the unit back to Way Too Cool for repairs unless other arrangements are specifically made in advance with Way Too Cool. The warranty covers such items as a malfunctioning ballast, or a broken switch. This warranty does not cover burned out or broken bulbs/tubes, it does not cover broken filter glass, or other damage due to mishandling unless the damage happened during the original shipping.

Testing Methodology
Our testing begins with a certified and calibrated UV meter. We assembled a testing rig that used ten (10) of our sterilization lamps. The test rig is set up to measure at both 1" from the probe and also at 1/2" from the probe. We tested in 9 places - three readings on each end and also in the center line.
Test protocol was at 73 degrees because of the warm up time for the tubes to reach maximum UV output. Colder temperatures would require a longer warm-up time to get to maximum UV output.
We turned on the fixture, placed it and waited one minute for it to warm up before starting to take thew first set of readings. In some cases, the UV output was still rising rapidly, so we waited an additional 10-15 seconds to start taking the first readings. We took a second set at 3 minutes, and a third set of readings at 5 minutes. You can clearly see the tube warming up during the first 1 minute to 1-1/2 minutes, then stable until after 4 minutes or so and declining a bit by the 5 minute readings.
We added up the 1 minute, 3 minute, and 5 minute readings at 1" and 1/2" to get test results for each lamp fixture over the 5 minute test period and then we added up the results from all 10 fixtures. The average for all 10 fixtures at 1" was 4,000 micro-watts/sq. cm., and the average at 1/2" was 6,800 micro-watts/sq. cm.
