Philips vs. Osram Lamps

Monday, October 27th, 2008

In an ongoing effort to provide the most sensible and accurate data, we’re still analyzing the results of our Philips vs Osram survey. We’ll get back to you shortly!

Brand Name vs Generic

Friday, July 18th, 2008

Why is it so important to buy brand name components when purchasing a high performance lamp for your DLP or LCD television? The answer won’t shock you, but you’ll think twice before buying generic.

First of all, let me preface by saying there is nothing wrong with purchasing generic parts. With some electronic components or consumable parts, generic is the most cost-effective way to go. The same goes for DLP and LCD projection lighting. Generic can be a great for your wallet in the short-term, but you may kick yourself 4 months down the line when your generic lamp goes kaput.

Hg, or mercury, vapor lamps are under extremely high pressure and it all comes down to the manufacturing process. The better the process, the better the lamp. There are two main parts to a UHP lamp, the lighting element, sometimes called the burner, and the reflector. Philips used to manufacture both in Belgium, but as demand and costs grew, Philips started manufacturing the reflector in China. The burners are still said to be manufactured in Europe since it’s a trade secret–and for good reason too since the burner is what makes the lamp ignition possible. For example, here’s a Philips E23h:

UHP Replacement Lamps
Explanation of key terms

Lamp modules – are made up of two main elements: the lamp (or bulb) and the cage (or housing) including electrical connector.

Lamps – are ultra high-performance light bulbs developed by the world leaders in lighting technology working in close cooperation with the projector & rear projection television manufacturers. The lamp (or bulb) is made up of two components: The burner (or lighting element) and the reflector. These are usually manufactured separately often times in different countries) and assembled together to create a UHP lamp.

Lamp module – are housings produced by the projector manufacturers to accurately seat the lamp and enable user replacement (each physically different projector model usually requires its own cage design). Also known as: lamp unit, lamp module, enclosure, cartridge, or housing.

Original Lamps -  are those manufactured by the original lamp developer holding the technology patent (e.g. UHP™ from Philips). Also known as: OEM.

Compatible Lamps – are lamps that are not the same type as the original lamp placed in the projector by the projector manufacturer. Specifications about brightness and lamp life are always based on the lamp system, which is the lamp and electronics that are designed to warrant safe operation and good performance of the system. Non-original lamps could be copy lamps. Also known as: OEM compatible, original Compatible, or aftermarket lamp.

Copy lamps – are lamps produced by unregulated manufacturing companies not holding the technology patents & not pre-installed by any projector manufacturer. Also known as: OEM compatible, original Compatible, generic, aftermarket, or knock-off.

Refurbishing (or re-lamping) – is the process of removing a used lamp from its cage. Also known as: relamping, refurbishing or redeveloping. Refurbished cages and housings usually have nothing to do with the operation of the lamp itself. The cages merely seat the lamp properly, and we recommend purchasing with a used, refurbished, or re-lamped product which is more environmentally and economically  sound. When purchasing new, look for a recycled label. Cages may be recycled and re-developed into a new lamp cage.
