This module carries the long numeric reference 5811118924-SOT rather than Optoma's usual BL- prefix, though it is the same lamp Optoma also lists as BL-FP280J. It covers the EH415, EH415e, EH415ST, HD37, HT50, W415 and W415e, a mix of home cinema and short throw variants from the same generation. No wattage or hours figure is published for this part.
If your projector's service documentation quotes DE.5811118924-SOT, BL-FP280J or the plain 5811118924-SOT, all three describe this identical module, so order using whichever code you have to hand. It is supplied complete with housing, ready to fit in place of the old unit without separating the bulb from its cage.

Common questions
Why does this lamp have a long numeric code instead of a BL- number?
Optoma uses more than one numbering system across its range. 5811118924-SOT and DE.5811118924-SOT are the manufacturer's numeric references, while BL-FP280J is the equivalent code in Optoma's more familiar BL- format, for the same lamp.
Does the EH415ST use a different lamp to the standard EH415?
No, the EH415ST short throw variant is listed against the same 5811118924-SOT module as the standard EH415, EH415e, HD37, HT50 and W415 range, so one part covers the whole family.
Is HT50 related to the EH415 in Optoma's range?
Both the HT50 and EH415 are listed as compatible with 5811118924-SOT, indicating they share the same internal lamp platform despite the different model names Optoma used for each market.
Do I fit the bulb separately from the housing on this module?
No, 5811118924-SOT is supplied as a complete module with housing attached, so it is fitted as one piece rather than assembled from a bare bulb and a separate cage.
What does the DE. prefix mean on DE.5811118924-SOT?
It is a regional documentation prefix used on some Optoma parts listings, but it identifies the same lamp as 5811118924-SOT and BL-FP280J, not a different or region-specific version.
This is a complete module — bulb already seated in its housing, so it drops straight in.
