Eight Viewsonic models draw on the RLC-108 lamp: the PA500S, PA500X, PA503S, PA503SE, PA503X, PA503XE, plus the PG603X and PS501X. Supplied as a module, the bulb is already fitted into its housing, so replacement means swapping the whole sealed unit rather than handling loose glass.
With eight compatible models sharing one lamp, it pays to read your projector's exact name off its casing before ordering, particularly between the closely named PA503S, PA503SE and PA503X. RLC-108 is the only code we hold for this lamp, with no bare-bulb version listed separately.

Common questions
What's the difference between the PA503S and PA503SE for this lamp?
None for the lamp itself; both take RLC-108, along with six other PA500 and PA503 models. The 'SE' distinguishes the projector variant, not the replacement part you need to order.
Does RLC-108 fit the PG603X?
Yes, the PG603X is one of eight Viewsonic models listed against RLC-108, alongside the PA500S, PA500X, PA503S, PA503SE, PA503X, PA503XE and PS501X. Checking the exact model plate is worth doing given how similar several of these names look.
Is this lamp available as a bare bulb instead of a module?
Not in this listing; we hold RLC-108 as a projector lamp with module only, with the bulb pre-sealed into its housing. If you need a bare-bulb equivalent, that would be a separate listing under a different code.
How do I check which of the eight models I have?
Look at the model name printed on the projector's body or rating label, then match it against PA500S, PA500X, PA503S, PA503SE, PA503X, PA503XE, PG603X or PS501X. Any of these confirms RLC-108 is correct.
When should I plan to replace RLC-108?
Watch for a dimming or yellowing image, a lamp warning icon, or the projector's lamp-hour counter approaching its limit. Any of these across the PA500 or PA503 range is a sign it is time to order a replacement.
This is a complete module — bulb already seated in its housing, so it drops straight in.
