Britesun's A70 model is described in its sales brochure, published in 1928, in the following words:
“BRITESUN SPECIALIST CARBON ARC ULTRA VIOLET LAMP
“BRITESUN SPECIALIST is a very compact, efficient, and moderately priced Carbon Arc Lamp. It is designed specially for Eye, Ear, Nose and Throat Specialists, G. U. Specialists, or for the General Practitioner for the treatment of localized conditions such as wounds, burns, sprains, stiff and swollen joints, infections, etc.
“All parts are of quality materials built for hard and long service. The perfectly balanced base is of vitreous porcelain enamel—the upright and adjustable arm brass heavily nickel plated. The 12-inch aluminum reflector has a highly polished exterior and French finish interior. ‘BRITESUN’ SPECIALIST is not top heavy, and is easily movable when in upright position.
“NEW AUTOMATIC CARBON ADJUSTMENT
“As exclusive feature of ‘BRITESUN’ SPECIALIST is the patented Automatic Carbon Adjustment which insures highest efficiency. After carbons are struck by a slight movement of the knob, the lamp needs no further attention. The carbons being placed in parallel position, burn evenly and maintain a perfect white flame, which is most essential for the best therapeutic results.
“BRITESUN SPECIALIST is a truly portable model in that it quickly telescopes from its full height of 56 inches to 36 inches without being taken apart, and can be conveniently carried to the bedside of a patient. TOTAL WEIGHT IS ONLY 20 POUNDS.
“BRITESUN SPECIALIST maintains a constant, rich flow of Ultra Violet rays of the correct wave length. Operating at 10 amperes, this lamp is guaranteed to produce a first degree erythema in from five to ten minutes, at 15 inches.
“This modality operates efficiently on either alternating or direct current without changes.
“BRITESUN SPECIALIST is delivered ready for service, including fifty Ultra Violet carbons, Localizing Attachment and pair of Protective Goggles.”
Illustrated in the ad above is the A60—“BRITESUN SINGLE ARC Carbon Arc Ultra Violet Lamp,” whose “performance reveals what price conceals.” Its sales brochure goes on to describe it as follows:
“A built in exclusive feature of the ‘BRITESUN’ is the Adjustment Automatic Feed. A perfect white flame, which is most essential for best therapeutic results as only in it is found the true chemical rays, is immediately obtained by drawing the carbons together. Crater Arc is not limited. The carbons can be spread to the desired distance to give the greatest amount of white light (Chemical Rays) of higher Therapeutic efficiency for either General or Local Radiation. No Springs or Coils to overheat and give way. All parts are of quality materials built for hard continuous service.
“Not only should quantity of Rays be taken into consideration—but most important is the quality of the Rays. The quality is not entirely dependent upon the style of impregnation of the carbons themselves, but also upon the amperage at which the Lamp is operated. The BRITESUN will operate efficiently with any carbon up to 10MM in diameter—best results, however, are obtained when the 8MM are used. If carbons of larger diameter are used at this amperage, an increase of volume but a decrease in the efficiency (due to lessening of the chemical ray) is the result. White Flame Ultra Violet Carbons, approximating the Solar Spectrum are supplied with the BRITESUN, but any of the various style Therapeutic Carbons, such as iron, copper or tungsten with a higher ultra violet co-efficient can be supplied.
“The BRITESUN operates efficiently on A. C. or D. C. without any changes. No transformers or generators necessary. Merely plug into your light socket and the BRITESUN is ready for service.
“BEAUTY THAT INDICATES QUALITY
“The BRITESUN was designed with a thought of beauty as well as efficiency in mind. Using only quality materials properly finished, carefully and correctly fitted, the result is the most beautiful Carbon Arc Lamp ever developed. Mounted on special 4-set ball bearing casters on a perfectly balanced polished aluminum base, the BRITESUN is easily movable when in upright position and is not top heavy. It is truly portable, in that it weighs but twenty-four pounds, can be telescoped without being taken apart, and carried conveniently to the bedside of the patient. All parts are brass, heavily nickel-plated—and aluminum highly polished—harmonizing with the finest office or hospital equipment. Will embellish the appearance of any office.”
The BRITESUN was delivered with 100 therapeutic carbons, a protective wire screen—similar to the one in the animation at the top of this page—an adapter, three applicators for localized work, three pairs of protective goggles, and an instruction book. Its price was $200.00.
The most expensive carbon arc ultra violet lamp that Britesun offered in 1927 was the “BRITESUN TWIN ARC” illustrated above. Its brochure claims:
“Just as BRITESUN SINGE ARC LAMP, through its matchless beauty of design and maximum efficiency in Ultra Violet output, won a predominating position in the field of Light Therapy, so is the new BRITESUN TWIN ARC LAMP winning its ‘place in the sun.’
“The day of the modality weak in Ultra Violet emission is past. The ever-increasing demand from practitioners and physiotherapists is for more Ultra Violet power. B RITESUN TWIN ARC LAMP meets this demand because it is a Carbon Arc Lamp of great intensity, producing a constant rich flow of Ultra Violet rays.
“BRITESUN TWIN ARC LAMP incorporates all the latest developments in Carbon Arc Therapy. The new automatic carbon adjustment is positive and fool-proof. After the lamp is lighted, it requires no further attention. The carbons are burned in parallel position, thus assuring an even burning, which is not the case when carbons are in vertical position.
“The BRITESUN TWIN ARC produces an equal quantity of short Ultra Violet and also gives the milder Rays of Ultra Violet and all the Rays of the Visible Spectrum and the Infra Red. This causes a complete relaxation of the tissues and opening of the pores providing ports of entry for desired Short Rays. It is now known that with the deep penetrating Rays of Infra Red running through the Visible Spectrum to the Bactericidal Region, the full benefit of the chemical action for medical therapeutics is secured.
“All the other excelling features of BRITESUN SINGLE ARC LAMP, beauty, workmanship, portability, durability and others, are incorporated in this new model. It is unexcelled for general tonic radiations.
“BRITESUN TWIN ARC LAMP operates efficiently on either A. C. or D. C. without any changes. No transformer or generators are necessary. Merely plug it into your light socket and the lamp is ready for service.
“BRITESUN TWIN ARC LAMP is delivered complete with 100 Therapeutic Carbons, Wire Protective Screen, Adapter and three Applications for localized work, three pairs of Protective Goggles, and its Technique Booklet telling ‘When’ and ‘How to use it.’”

An attraction to carbon arc light therapy as an alternative medicine still appears to be strong. Interested buyers on Ebay recently bid enthusiastically on a little 24-page booklet on CarborayTherapeutic Lamps manufactured by The Cincinnati Automatic Machine Company. This 1928 sales brochure described and provided instructions for the use of its Carboray ultra violet and infrared sun lamps that were suppose to cure tuberculosis, rickets, rheumatism, headaches, infections, impotency, hay fever, goiters, kidney disease, poison ivy, acne and pimples, baldness, anemia, body odor, asthma, and so on. This old stapled pamphlet displayed its carbon arc ultra violet health lamp with an amazing price of $47.78.
