MegaUVBLight is a small Tennessee store that sells one thing: the four Mega-Ray self-ballasted mercury vapor UVB bulbs, made in Germany and shipped from Mega-Ray’s US distributor. If your facility keeps reptiles under mercury vapor UVB lamps, we can supply them โ with the paperwork your purchasing process needs.
๐ PO-friendly
Add your PO number in the order notes at checkout. Quotes, W-9s and invoice documentation by email.
๐ฆ Fresh stock, any quantity
We hold no inventory โ every order ships from the distributor’s current stock. Free US shipping and a 6-month warranty on every bulb.
๐ฌ Peer-reviewed data
The BIAZA UV-Tool (JZAR, 2016) rates the Mega-Ray 100W and 160W for all four Ferguson zones โ one of five lamps in its table.
Ordering with a purchase order
- Order online with a credit or purchasing card and add your PO number in the order notes at checkout โ it appears on your order records.
- Need a quote, W-9, or invoice documentation before ordering? Email support@megauvblight.com and we’ll provide it.
- Pricing is the listed price for every customer โ no negotiation required and none available.
Quantity orders
Quantity orders are welcome: a recent 24-bulb institutional order shipped the same day it was placed. Orders placed before 2 PM Eastern ship within 0โ1 business days, and because bulbs come from the distributor’s current stock, they arrive fresh rather than warehouse-aged.

The test data
We only make claims we can show you. UV Guide UK measured Mega-Ray lamps in 2006 and again in 2014, and the peer-reviewed BIAZA Reptile & Amphibian Working Group UV-Tool rates the 100W and 160W for all four Ferguson zones. The measurements, their methods, their stated limits, and the manufacturer’s wattage and mounting-distance table are assembled on one page, with links to the original reports.
