| Q3 |
|
What is the difference between a Philips lamp and another make of lamp? |
| A |
|
The Philips name guarantees a product that meets the requirements of the purchaser as much as possible. This is true not only for the quality of the product and the components used, but also for the price and pre-sales and after-sales service, for example concerning advice about the product and the handling of possible complaints. |

| Q4 |
|
Why is an energy-saving lamp environmentally friendly? |
| A |
|
An energy-saving lamp uses about 80% less energy than a light bulb. This saves fossil fuels and reduces emissions from power stations. The lamp does however contain a few environmentally unfriendly components (a small quantity of mercury). At the end of its life, the lamp must be disposed of as "small chemical waste" (SCW). |

| Q5 |
|
My energy-saving lamps have been failing earlier than the specified life. Why is this? |
| A |
|
If an energy-saving lamp had a lifetime shorter than 1/3 of the average lifetime, then the lamp must be forwarded for more detailed inspection. This applies to energy-saving lamps within 2 years of purchase. A short lifetime is often caused by the lamp being used incorrectly, namely in combination with a dimmer or in an outside fitting with a dimming or proximity switch. You can contact our Customer Service for more details. We will treat this case-by-case. |

| Q8 |
|
Is special disposal required for my halogen lamps? |
| A |
|
Only gas discharge lamps have to be disposed of as "small chemical waste" (SCW). These contain small quantities of mercury. This concerns: Energy-saving lamps, TL, PL, SOX lamps. Light bulbs and halogen lamps are hence not SCW. |

| Q9 |
|
Which lamps emit the least UV output for illuminating e.g. a painting? |
| A |
|
Philips lamps for general use are designed to have as less as possible unwanted UV output. The most critical lamps are halogen lamps, but most Philips halogen lamps use special glass to limit the UV emission; we indicate this on the packing as UV Block. |

| Q10 |
|
Which is more cost efficient, halogen or a fluorescent lamp? |
| A |
|
A fluorescent lamp is about 4 times more energy-efficient then a halogen lamp. The cost efficiency is of course dependant on the purchase price of the lamp, but fluorescent is always more efficient. |
