Item #: SCP-XXXX

Object Class (Revised 2016-██-██): Euclid

Special Containment Procedures (Revised 2016-██-██): Containment is focused on preventing the production of dichroic color filters with the properties described below. Foundation assets have been placed within facilities that produce dichroic color filters to monitor purchase orders; any purchase orders for filters that can manifest SCP-XXXX are to be immediately canceled and forwarded to Dr. Nikoleva at Site-58. Additionally, workers’ compensation and accident claims related to event, theatrical, television and cinema workers are to be periodically reviewed by Foundation agents for claims that fit the profile of SCP-XXXX incidents.

Description (Revised 2021-██-██): SCP-XXXX is an anomalous property of dichroic color filters intended for use in high-powered lighting instruments to produce a particular hue of the color ██████. The colored light produced by these filters has been found to “stabilize” calcium ions (Ca2+) by contributing two electrons to each calcium ion; the electrons are produced in a manner inconsistent with understood photoelectric principles but superficially similar to spontaneous pair production. However, the energy levels of the photons are six orders of magnitude too low for typical spontaneous pair production and the result of the photon decay is two electrons, rather than the expected electron-positron pair. The affected calcium temporarily has an anomalously strong electron bond; its ionization energy has been experimentally verified to be above 300 eV, rendering it inert to chemical reaction while it remains in the affected state. This effect has a half-life of approximately thirty hours, after which the calcium’s electron configuration will spontaneously revert to baseline.

This effect can be produced by placing a dichroic filter of the appropriate specifications in front of a light source of at least 8500 lm, with a color temperature between 3000 and 3500 K. This is within specification for a typical Leko-type ellipsoidal reflector spotlight fitted with an appropriate lamp, and the SCP-XXXX effect has been successfully demonstrated using multiple different types of standard theatrical lighting instruments. This effect has been verified to be produced by dichroic color filters manufactured by the █████, ████ ████, and ███████ companies; no relevant chemical or manufacturing commonalities have been identified between these different types of filters, and custom manufactured filters using non-standard coatings have additionally been verified by Foundation researchers to produce this effect. Other methods of precisely producing this color, such as █████████ dye lasers, have been tested by Foundation researchers but do not to appear to produce any anomalous effect.

Exposure of living cells to the colored light has any number of deleterious effects. The loss of ionic calcium in both eukaryotic and prokaryotic cells can cause rapid cell death. Larger multicellular organisms (eg humans) will attempt to compensate by transferring calcium from other sites; this can stave off more than superficial cell death (manifesting as a “rash” on the skin) for a time but will cause rapid manifestation of symptoms of calcium deficiency, as well as a buildup of “calcium gas” (the inert “stable” calcium) inside cells. The long term health effects of exposure are not well understood, but a >70% rate of skin and other surface cancers forming within two years in D-class personnel and others who have been exposed to SCP-XXXX has been observed. There is also evidence of macular and bone degeneration as well as optical nerve drusen in long term skin exposure subjects. Most seriously, direct exposure to the eye will begin immediate degradation of both the optic nerve and the skull bone tissue behind the eye socket. As demonstrated by live tests on rats and D-class personnel, any amount of direct ocular exposure can cause symptoms including blindness, loss of cerebrospinal fluid, seizures, meningitis, brain lesions, and death.

SCP-XXXX was brought to the Foundation’s attention in February of 2007 after the hospitalization of two technical personnel and one actor (incident SCP-XXXX-A) working at the ███████ Theater in ███████, Washington. Initial containment was focused on the specific instrument, lamp and filter implicated in incident SCP-XXXX-A. After a second incident (incident SCP-XXXX-B) involving over 150 workers at █████ Arena in ██████, New York in December of 2015, investigation and analysis of SCP-XXXX was reopened and documentation significantly revised to take new information into account. Previous documentation maintained as appendix A for historical purposes. For more information on incidents -A and -B, see appendix B.

Compensation to the survivors and the families of victims of incident SCP-XXXX-B, to be distributed through IATSE Local ██ and AEA New York, was requested by Dr. Nikoleva and authorized by Site Director Jacobs as of 2016-██-██.


Object Class: Safe

Special Containment Procedures: SCP-XXXX is to be kept in a standard Safe-class storage locker at Site-58.

Description: SCP-XXXX is a █████ ████ ellipsoidal reflector spotlight manufactured by the ███ company. It is fitted with a 575W/115V ███████ brand HPL bulb and a ████ brand color filter in ██████.

Exposure to light from SCP-XXXX causes health problems in humans. Short term skin exposure manifests as a rash. More seriously, looking into SCP-XXXX directly while active can cause severe eye or brain damage in a very short period of time.

SCP-XXXX was brought to the Foundation’s attention in February of 2007 after the hospitalization of two technical personnel and one actor working at the ███████ Theater in ███████, Washington. Witnesses were questioned before being given standard class-A amnestics, leading Foundation agents to discover the anomalous instrument.

As of 2007-██-██, Dr. Nikoleva is in charge of testing for SCP-XXXX. No testing is currently scheduled; test requests or proposals should be submitted in writing.
