The bulb surface temperature may reach a few hundred °C during operation.
Always wait at least 10 minutes after turning off the lamp for cool down before
performing a bulb module replacement.
Caution

from hands left on the bulb may shorten the bulb lifetime.

Thorlabs offers pre-aligned bulb replacement modules for SLS201L and SLS202L
light source. The replacement modules are available on www.thorlabs.com under
the SLS251 and SLS252 item numbers, respectively.

underside of the unit. Using the included 5/64" (2 mm) hex key, remove the screw
closest to the end of the unit from both the left and right sides. DO NOT remove
the screws closest to the fan ventilation holes.
