Hi Friends,

Follow this step by step guide on how to build your own UVB-NB handheld device. The big advantage of this product is the fact that you can use either 1 or 2 bulbs, i.e., 9w or 18w (2 x 9w).

2- Do not use this guide to produce a device for monetary sale (it is suitable for personal, supervised use only).

Step by step:

1- Buy the following car work light (around $29):

2- Buy the UVB-NB PL-S 9w/01 bulbs, 1 or 2, it's up to you (around $50 each):

3- Remove the acrylic transparent cover of the work light.  For this, you will have to remove 2 small bolts.  After removing these bolts, throw them away, since you won't need them anymore.

4- Replace the original 13W bulbs for the 9W UVB-NB bulbs carefully. It's tricky. You may have to bend the bulb before attaching or detaching.

5- Before the phototherapy session make sure that the acrylic cover is detached , since it filters UVB-NB wavelength. This cover has only a storage protection purpose (attached w/o screws).

6- Wear appropriate UV-blocking safety glasses during the whole session. You can purchase a pair (around $3) at:

7- Good luck.
