To change the bulbs in an older Sun Quest Pro 16SE tanning bed, first, ensure the unit is unplugged for safety. Remove the acrylic panels carefully by unscrewing any fasteners or lifting them off, depending on the model. Next, carefully remove the old bulbs by twisting them out of their sockets, then insert the new bulbs by aligning them properly and twisting them into place. Finally, replace the acrylic panels, secure them, and plug the tanning bed back in.
The bulbs are changed on a Sunquest Pro 16SE tanning bed by unscrewing the side panel and sliding out each bulb. Replacement bulbs are then put in and the panel replaced.
