Frequently Asked Questions

What is the difference between the B-Series and the E-Series UV lamps?

This is one of the most common questions we get on these lamps — here is a clear comparison:

• B-Series (SKU 2218) — Battery operated. Runs on 5 C-cell batteries for up to 5 hours. No power cord required — fully portable and field-ready. Peak intensity: 730 µW/cm² at 6". Single 4W tube. Best for applications where portability or remote use is needed.
• E-Series (SKU 2211–2214) — AC plug-in (corded). Requires standard 120V outlet. Available in 4W single tube, 6W single tube, and dual 4W tube configurations. Peak intensity ranges from 555 to 1,280 µW/cm² depending on model. Best for fixed clinical, lab, or exam room use where consistent power is available.

If you need to take the lamp to the patient or use it in locations without a power outlet, the B-Series is the right choice. If the lamp will stay in a fixed clinical setting, the E-Series offers more wattage and intensity options.

What wavelength does the B-Series emit?

The B-Series emits long-wave ultraviolet light in the UV-A range (approximately 320–400 nm). It is not a UV-B or UV-C lamp. Confirm the required wavelength for your specific application before ordering.

What batteries does this lamp require?

Five C-cell batteries are required. Both standard alkaline C-cells and NiCad rechargeable C-cells are compatible. Batteries are not included. A fresh set of alkaline C-cells provides approximately 5 hours of continuous use.

Is eye protection required?

Yes. UV-protective eyewear is required for both the operator and the patient during UV-A exposure. Never look directly into the lamp during operation. Follow your facility's UV safety protocols at all times.

Is a replacement tube available for the B-Series?

Yes — the B-Series uses a 4-Watt BLE-22B replacement tube. Call us at 866-218-0902 to confirm availability and order the correct replacement tube for your lamp.

Is this lamp made in the USA?

Yes — the B-Series lamp housing and assembly are made in the USA. Bulbs (tubes) are manufactured outside the USA.
