It's never a good idea to wait until Dell projector lamps lamp blow before buying replacements. People avoid keeping a spare because they think Dell projector lamps are expensive. However, this is false economy - without a working lamp, a projector is just a piece of useless hardware, so why take the risk? Besides, it isn't always necessary to buy branded products. There are unbranded Dell projector lamps that are just as good as the genuine manufacturer's replacement - except they lack the Dell logo and accompanying price tag.
The important thing to ensure when buying unbranded Dell projector lamps is that they are made to the same high standards as the original. This means seeking out a reputable supplier - preferably, someone who sells both unbranded Dell projector lamps and the manufacturer's original versions. This company will value its customers highly, know their products and will be keen on maintaining good relationships with Dell.
The most important influence on cost is the lifespan of the lamp. Depending on the manufacturer, Dell projector lamps can last anywhere from 1000 to over 4000 hours. However, this must be offset against the manufacturing quality. It is pointless buying a cheap 4000 hour lamp if the bulb blows the moment the projector is moved.
Remember, though, that this works the other way, too. Original projector lamps have a finite lifespan - they are designed to need replacing after a safe number of hours by the brand manufacturer. This ensures that old lamps won't damage the projector, but it also means you may get a longer life from an original.
Original Dell projector lamps are high quality products that are designed to last a long time and using these branded lamps ensures your projector model is covered under the manufacturer's guarantee. However, good quality unbranded alternatives can be made to exactly the same stringent specifications. The best way to know what you're getting is by checking the "kite" mark. All Dell projector lamps must undergo strict quality control tests to ensure the potentially dangerous mercury vapour does not come into contact with the outside air, and that users are protected from the dangers of shattering glass. They must also have the density of mercury vapour laid down by Dell.
Although buying online is cheaper than buying offline, don't be lulled into a false sense of security by so-called Dell projector lamps which seem unrealistically cheap. Just as with perfumes and fashions, there are fake projector lamps on the market which use realistic branding and packaging to create "manufacturer's original" products which are nothing of the sort. Invariably they have been made in cheap foreign sweat-shops where safety and quality control is non-existent. It is far safer to buy a quality checked, but unbranded lamp from a trusted supplier.
When it comes to Dell projector lamps, most people play safe and buy the original from a reputable known stockist. However, this often means they take a chance and don't keep a spare. A far better option is to have the manufacturer's original lamp fitted, and then order a low cost non-branded "spare" from a trusted supplier who offers a money-back guarantee. That way, you are covered from all angles.
