Are BL-FP280A and BL-FU280A the same lamp?
Yes, both are alternative part numbers for this identical 280-watt lamp, as are H1Z1DSP00004, DE.5811100.173 and DE.5811100173. Different brands and resellers apply different codes to the same physical part.
Does this listing come with a housing?
Yes. This is a complete module — the 280-watt lamp fitted into its housing — so it fits directly into the projector without needing to transfer the bulb from an old unit.
How long is the rated life of this lamp?
It is rated for 2000 hours of use. Once your projector's lamp-hour counter nears that figure, or picture brightness starts to drop noticeably, it is a good time to plan a replacement.
What should I check before ordering a replacement lamp?
Match your projector's exact model number against the sixteen listed here, or compare the code on your existing lamp against 5811100173, BL-FP280A, BL-FU280A, H1Z1DSP00004, DE.5811100.173 or DE.5811100173 to confirm you are ordering the correct part.
