Quoted from Osram/Sylvania Document # DQ4-144-059WARNING: In accordance with ANSI/IESNA Standard RP-27, this XBO bulb is a Risk Group 3 product. Read and understand this warning before using this bulb! XBO lamps are at high internal pressure when cold (up to 35 bar or approximately 525 psi) and at operating temperature (up to 80 bar or approximately 1200 psi at bulb wall temperatures of 600°C to 800°C). Therefore, XBO lamps may unexpectedly rupture resulting in the discharge of hot fragments of quartz and/or glass and metal . In the event of such a rupture, there is a risk of personal injury, burns and fire. Only handle lamps with their protective covers in place. Do not handle lamps without their protective covers unless government-approved (OSHA-approved in the U.S.A.) safety glasses, facemask (with neck protector), chest protector, and gauntlets are worn. RUPTURE & RADIATION (UV-VISIBLE-IR) HAZARDS: 1. Intense ultraviolet (UV), visible, and infrared (IR) radiation is also generated during operation. This radiation can cause permanent damage to the eyes (including blindness) and serious injury to the skin (including burns and blistering). Some operating lamps also generate ozone (O3). Others, designated “OFR,” are constructed of materials that prevent the generation of ozone. See the “Ozone Generation” section below. 2. To avoid eye damage, other personal injury and/or property damage, the lamp MUST be operated in a suitable fixture. A suitable fixture is one that will prevent the arc from being viewed directly while operating. It is ventilated to the outside for those lamps that produce ozone and, in the event of a rupture, will prevent hot (up to 800°C), flying fragments of quartz and/or glass or metal from escaping into the surrounding area. 3. To minimize the risk of a lamp rupture, the lamp must be replaced at or before the end of rated life (see catalog for rated life) or when the lamp shows signs of advanced blackening or quartz devitrification (recrystalization, a white, frosted appearance). 4. XBO lamps are constructed of quartz glass, tungsten electrodes and either tungsten support rods or molybdenum foils. High wattage XBO lamps used for cinema film projection have nickel-plated end caps (bases). Reflectorized XBO lamps have a dichroic-coated borosilicate glass reflector. LAMP DISPOSAL: 1. There is a risk that a lamp could rupture because of its high internal pressure (both hot and at room temperature). A lamp rupture could result in personal injury or property damage from flying fragments of glass and/or metal. Therefore, spent (end-of-life) lamps should ALWAYS be stored in the protective covers and packaging in which they originally came, and ultimately de-pressurized before release for disposal. The following is one example of a de-pressurizing method for XBO lamps prior to disposal, but it may not be the most suitable or appropriate method depending on the circumstance: · The operator must wear government-approved (OSHA-approved in the U.S.A.) safety glasses, facemask (with neck protector), chest protector, and gauntlets during this entire procedure. · With protective lamp covers in place, place lamps1 into steel drum2 and lock down cover with bolt ring and bolt. · Drop drum onto solid surface (concrete floor) from at least five feet. Increase height as needed to ensure all lamps are de-pressurized. · Wait for dust to settle (about 5 minutes) before opening drum. Loosen bolt and allow gas to escape before complete removal of cover. 1 The lamps should not exceed the half-full point in the drums. Adjust the maximum number of lamps accordingly. 2 8, 20, or 30-gallon drums, depending on quantity of lamps to be de-pressurized, are available. Drums of 20- gauge steel are recommended and are available from many safety supply companies. 2. Disposal of spent lamps must be in accordance with applicable federal, state/provincial, and local regulations. State laws differ in their disposal requirements. 3. U.S. lamp users may obtain information concerning relevant agencies and disposal regulations from the Federal Superfund Hotline (Resource Conservation & Recovery Act) at 800-424-9346. Information may be available as to the appropriate state agencies to contact regarding disposal issues. 4. OSRAM SYLVANIA Products Inc. cannot advise lamp users as to general or specific disposal regulations for federal, state/provincial, and/or local municipalities.

"I've heard of wrapping the bulb up in a 50lb popcorn seed bag and smashing it with a happer. "Hey Ken, what the H--- is a happer and where can I get one?  Joe, film has an incredible range. A. Adams "zone" system was (and probably still is) the best way to exploit this with large format negatives. The concept is to tweak the exposure and developer to match the contrast range you want and place it correctly on the curve. Check out this for a better explanation of development tweaking. There could be a no-cuts taking of the film, but using a time code marking the different events so the various sections of the film could be processed differently for perfect exposure range. Adding fill light would eliminate the need for extreme low light imaging. We expect you to have this project completed under budget within the week.

Possible uses for xenon bulb parts:TUNGSTEN CATHODES--Reloaders might fit them to high-power cal.23 or .223 cartridges as A.P. projectiles (with increased wear on the rifle barrel's lands, however) I think tungsten is heavier than lead. TUNGSTEN ANODES--Use as balance scale weights for use by reloaders, chemists or darkroom photographers. Or make into chess pieces by painting or grinding designs to differentiate the ranks. ---Since tungsten is valuable, they might be sold to a metal reclamation company. XENON BULB ENDCAPS-- Wire with sockets and a dimmer to make a hanging chandelier for your home theatre. All needed parts available at Home Depot lamp center. Five or seven in a circle on a barrel hoop would be a minimum-cost approach, but your creative sense can do better. Or use seven for a menorah, or nine for a hanukia, using candles or decorative electric bulbs. Since my last steady job was at a single screen, the bulbs accumulated on the shelf in their plastic safety enclosures within cardboard boxes rather slowly. But when I needed shelf space, I would don the OSHA protective gear, wrap each bulb in an entire newspaper, put it into a leg cut from a pair of jeans, and hit it with a hammer, on a concrete floor, resulting in a muted "pop." After removing the parts to recycle, I would package the glass in the newspapers, pack them in a corrugated carton marked Caution! Broken Glass! seal it with duct tape and place it next to the trash barrel for the porter to dispose of.

Jeez, Jon!Those guys at Osram must be totally trying to cover their asses with that form!! C'mon guys-its just a xenon bulb, not a nuclear weapon. Superfund disposal site? All thats in a xenon is quartz, tungsten, ceramic and xenon gas. None of which are toxic or unstable. Additionally, anyone that tries to handle a HOT xenon is just plain STUPID. -Aaron
