Projector Lamp Replacement

[Glassman]

My projector, an Optoma HD27E, has started to show a warning on startup. It needs a replacement lamp.

I can find plenty of options of where to buy but what's not clear is the type of lamp required. I'm not even sure what the projector has in it currently. LED? Incandescent? Metal Halide? Halogen? Mercury Vapour? DLP? I have no idea what any of these mean in terms of performance but they are all listed as compatible.

Which is best?

There may be better options, but you can put your make @ model in here -

Thanks.

What's confusing and very annoying is that even when I try the part number from the manufacturer, all the different types of lamp correspond to it.

Well, you can cross out LED, incandescent and halogen. None of these apply to the HD27. Both incandescent and halogen use a wire filament like the old 40 Watt, 60W, 100W light bulbs. A bit of wire glows in a vacuum. LED should be familiar to you given that LED lamps are common for domestic use. Your projector predates this tech at the original price point.

You can also rule out DLP. This is the image creating technology, not the lighting tech.

What's left then is metal halide or mercury vapour. These are both types of arc lamp. A high voltage causes a spark to form a bridge between two electrical elements.

Really though, all you need do is choose a lamp for your specific model of projector. Yours is the 27E, not the BE, and not the EH.

You want an original lamp, not a generic replacement. This could be an original lamp with an original lamp housing (the most expensive version), or an "original inside" - the lamp is genuine but the housing is a copy. Or, you buy an original bare lamp. This can be the cheapest option, but check prices.

Depending on price, I've always gone for either the bare lamp or an original inside with a copy housing. In both cases, I swap the lamps over. This is a rubber gloves operation. You do not want to touch the lamp with bare fingers.

If it's anything like the Barco high pressure lamps I remember you often don't want to touch it full stop. Admittedly these were high output ones but once they were old they could start to get a bit bulgy and they were inside a housing for a reason.

Amazing, thank you.
