The Sperti Vitamin D Light Therapy Lamp delivers high levels of broad spectrum light, including UVB rays. This lamp comes with a few protective features to avoid overexposure. It relies on a rugged body design for top performance and requires shorter therapy sessions than many other sun lamps, but the unit requires extra care to avoid skin damage. This lamp's short therapy sessions make it best for people who are constantly on the go.

This broad spectrum sun lamp delivers something most light therapy lamps specifically avoid – UV light. This particular lamp radiates UVB rays, which are less harmful than UVA rays but can still come with many risks. Soaking in UV rays is also a fast way to increase vitamin D levels and treat certain skin conditions like psoriasis.

However, overexposure to UV rays can damage the skin and increase the risk of skin cancer. For this reason, most sun lamps include diffusers and shields that restrict UV rays. This lamp does the opposite. It supports full UV exposure and mimics the appearance of natural sunlight. To protect your eyes during sessions, this lamp comes with two pairs of protective eyewear. The lamp uses four D/UVF bulbs, which have a lifespan of 1,000 hours. You can purchase a set of four replacement bulbs from Sperti, but be aware that they are relatively expensive. If you'd prefer a lamp that shields you from UV rays, you should consider Day-Light Sky.

Because you only need between five and 15 minutes of sunlight daily to produce adequate levels of vitamin D, Sperti sessions can be as short as five minutes and don't extend beyond 15 minutes. This lamp comes with a short timer with a maximum interval of five minutes. After it reaches the allotted time, it shuts off automatically. This short timer reduces the risk of overexposure and is an easy way to track more advanced treatments.

You can't adjust light intensity with this lamp. Instead, it projects with maximum intensity at all times, and the manufacturer recommends a minimum distance of at least 15 inches to avoid burns. The lamp itself measures 2 feet tall, and it weighs nearly 15 pounds with the lights installed. The unit comes with a removable 8-foot cord. It is flicker-free and has been designed to eliminate buzzing sounds which used to accompany this kind of lamp.

Despite its powerful light levels, this sun lamp does not require a doctor's prescription. The automatic shutoff control and durable construction serve as vital safety features, so you can use this as a therapeutic tool relatively often without much additional risk. Even with these features, the sun lamp produces potentially harmful levels of light and requires extra care during usage.
