②Bottom,③Top side,④Top inside,⑤Filter ring inside). And assemble the lamp block in reverse
order of 2).
Hint: When fixing Front heat sink, adjust its angle by rotating it so that the lamp cartridge does not rock on
the flat top.

ignition property and luminance.
2) It is not good to apply too much heat sink grease. This may cause lamp ignition failure. Apply
the grease so that the metal part can be seen under the grease.
3) When you apply grease, do not contaminate the top of the bulb and IR cut filter with the grease.
4) When you attach Front heat sink, pay attention to IR cut filter. Do not remove it. Do not
contaminate it with a finger print and so on. Do not scratch it.
