“…Popular light filters include the CLS-200-X (Madico, Inc, Woburn, Massachusetts, USA), which is a clear flexible film with good colour rendering 10. Other possible options include Dermagard (Bonwyke Ltd, Fareham, UK) and SunGard (Film Technologies Inc, St Petersburg, Florida, USA), which are both UV-protecting films 11 12. These light filters may also be used for extremely photosensitive lupus patients during surgical procedures, to decrease exposure to UVR.…”

A patient in her 60s with systemic lupus erythematosus presented to an outpatient dermatology clinic on multiple occasions, with exacerbations of cutaneous lupus after exposure to surgical lighting during dental procedures. Her photosensitivity to surgical lighting suggests that artificial light sources pose potential triggers of lupus erythematosus in extra photosensitive individuals. This case report summarises those potential triggers and some options to decrease exposure from surgical lighting.

“…A pilot study investigating the effect of different lighting types on patient symptoms showed that UV-emitting bulbs (compact fluorescent lamp and energy-efficient halogen) were erythema-inducing. These two light sources should be avoided in favor of light-emitting diode bulbs, which were identified as a safer, non-UV-emitting alternative [19]. Surgical lighting was also recently reported to induce flares in a photosensitive LE patient [20].…”

Introduction Treatment and prevention are of critical importance in patients with cutaneous lupus erythematosus (CLE), as the disease can have a devastating effect on patient well-being and quality of life. Areas Covered We conducted a selective search of the PubMed database for articles published between December 2010 and November 2015. This review encompasses both non-pharmaceutical (photoprotection, smoking cessation, drug withdrawal, and vitamin D replacement) and pharmaceutical (topicals, antimalarials, immunosuppressives, biologics, etc.) interventions used in the treatment of CLE. Expert Commentary Recent work has expanded our understanding of established therapies as well as introduced new treatments for consideration, though existing medications still prove inadequate for a subset of patients. Changes in trial design may help to alleviate this issue.

“…They hypothesized that UV can “leak” through areas of the bulb where the phosphor is thin, or missing, and that this does not occur with traditional, linear fluorescent tubes. A second, more recent, study reported that a 30 min exposure to a U‐shaped Biax CFL at a distance of 5 cm could produce a Grade 2 erythema (definite erythema with sharp borders) in a skin phototype II individual (observed 24 h postexposure) and a 15 min exposure could produce a Grade 1 erythema (faint erythema filling the majority of the test site) in a skin phototype I individual. However, the illuminance at this distance was close to 1000 lux, which does not represent a typical use condition.…”

There have been many recent reports regarding the potential risks of UV emissions from compact fluorescent lamps (CFLs). In some of these reports, the robustness of the measurements was difficult to discern. We conducted round-robin measurements, involving three lamp manufacturers and two government research laboratories to gather reliable data on the UV emissions from commercially available CFLs. The initial sample of lamps consisted of 71 spiral-shaped CFLs purchased from local retailers. From the initial sample, 14 "high UV emitting" CFLs were chosen for further evaluation. We compared the UV emissions at a distance of 20 cm with the UV exposure limits (ELs) published by the International Commission on Non-ionizing Radiation Protection (ICNIRP). We found that the allowable exposure time for measured lamps ranged from 21 to 415 h. This indicates that the emissions would not exceed the short-term ELs that have been established by the ICNIRP for healthy individuals. We also evaluated the potential long-term risk and found it to be insignificant. There was a large variation in the UV emissions found, even for lamps from a single package, indicating that it is impossible to predict the UV output of a CFL based on its physical appearance and model designation.
