If the lamp is not operating you will see a yellow brown deposit inside the lamp in addition to a bead of mercury for Gallium lamps. For iron additives you need to look very closely but metal like "filings" are visible on the inside of the lamp. You can also tell lamp type by looking at the color of the light when operational. NOTE you should never look directly or indirectly at reflected lamp light, as it is DANGEROUS.

We are not appraisers. We recommend that you take your lamp to a high quality reputable antique shop and ask them to either appraise your heirloom or send you to someone who can. On a positive note. While in that antique shop look around. Find one that is close in both style and size to yours. You will probably be pleasantly surprised at what these old lamps are going for.

It is essential that you change your UV lamp annually. The ability of the lamp to emit UV light decreases over time. Remember - UV light is invisible! Even though the lamp is still glowing after one year, there might not be enough UV light reaching your water to be effective.

The UV light that is inactivating microorganisms in water is non-visible light, therefore the blue light that you see coming off a UV lamp is not what's doing the work. A UV lamp can be described as a low pressure mercury vapor lamp, which means it fires via mercury vapor. Over the course of a year that mercury is being used up resulting in a slight decrease of UV intensity. At the end of one year a Sterilight UV lamp has decreased in it's intensity by approximately 20%.

First it should be noted that the "gauge" system for hooks is not the same as for body jewelry. The larger the number, the bigger the hook. To name a few examples commonly used in suspension, a 7/0 salmon hook is roughly the same size as 10ga jewelry, and a 9/0 salmon hook is roughly the same size as 8ga jewelry. It is important that stainless steel hooks are used -- most fishhooks are made of a high carbon coated steel which will quickly rust when autoclaved.

No, as mentioned previously, the Phosphenic Lamp has no calorific properties. It is then no use to take glasses or contacts off for the practice of Phosphenic Mixing.

Depending on the selected lamp, the duration is anywhere from 500-6000 hours (see product information sheets for specific models).

Yes if your vehicle was first used on or after 1 April 1980. The inspection of rear fog lamps is confined to the one rear fog lamp which is required to be fitted to the centre or offside and operates with dipped head lamps and the ignition switched on. An indicator (tell tale) lamp is required on the dash so you know the fog lamp is on.

All Ultrabond adhesives respond to exposure to high intensity medium pressure UV lamps in the range of 365nm (long wavelength) and 100 milliwatt/cm? intensity. Some Ultrabond adhesives function with low intensity lamps. Cure times are longer and gap fill ability will be lower under these conditions.

Eventually, you will have to replace the lamp in your scanner. This can be postponed by making sure to turn off the lamp anytime you aren't actively using your scanner. SuperWarehouse offers a complete line of replacement bulbs for scanners. Simply call one of our Product Specialists at 1-800-814-5410 for assistance.

We recommend that you ask your coating and Ink supplier if they can guide you in the right direction. If not, please call American Ultraviolet Company and we will be happy to assist you.

LAMP is a joint project of the MIT Student Information Processing Board (Josh Mandel/Keith Winstein) and MIT Cable Television (Randy Winchester/Jon Ward). LAMP is generously supported by MIT iCampus (MIT/Microsoft Research) and StreetFire Sound Labs, and is supervised by Professor Hal Abelson.

If you need to tell someone, have him or her sign a "non-disclosure" form that says that they are not allowed to talk to anyone else about the idea. You can find a sample NDA that you may print out on the right side of our home page right under the little Ghostline ghost. We are not attorneys so we cannot give you any legal advice but these are the differences as we understand them. A utility patent is for an invention that is utilitarian (it has a use).

The ultraviolet wattage - which is the "killing power" - will start to diminish after twelve months.

RUVA is a lamp that has a special reflective coating inside the lamp. They generally have a lower UVB percentage, such as 2.6. Other lamp manufacturers designate that their lamps have built-in reflectors by using the letter "R". If it just has an R, that usually means that the lamp is a reflector lamp with a higher UVB percentage. Lamps with reflective coatings direct most of the UV rays directly onto the tanner. They intensify the tanning session.

The Plug: On newer table lamps, the prongs on the plug are different sizes. The larger prong is (should be) the neutral. The receptacle in the wall has different sized slots; the longer slot is (should be) the neutral. For safety, the plug should fit in only one way. The cord: If you rub your fingers along the two sides of the cord, one should be smooth while the other has little ridges. The ridges are (should be) on the neutral wire side.
