What is the difference in cycle light bulbs between Krypton, and Halogen?

Question

I need some replacement parts for our eurolight cycle lamps. There is a choice of krypton or halogen bulbs, what are the advantages of the two types?

I have had these lamps for years, have never yet had to replace a bulb, but the have storage for spare bulbs.

Answer 1

Krypton bulbs contain pure inert gas which allows the filaments to run at a higher temperature, emit a whiter light, and enables enhanced visibility for a given power consumption compared to Vacuum bulbs.

Halogen bulbs contain a technically advanced mixture of active and inert gases. The active component re-cycles tungsten from the glass back onto the filament, enabling the use of a hotter, brighter filament. They are the ultimate filament bulbs producing the best combination of white light, visibility, and safety. The glass is thicker than krypton and vacuum bulbs, and is hardened to produce a mechanically stronger bulb.

Answer 2

Erm no, don't think you mean that, Krypton is a Noble gas (like Argon, Neon, even Helium) while Halogen bulbs as so called because they have Halogen gases like iodine or Bromine in them.

Halogen lamps have tungsten filaments and can run at higher temperatures than Krypton filament bulbs making them slightly more efficient, but Krypton bulbs can also be gas-discharge (like the tubes in a strip-light) lamps where the gas itself causes the luminescence as it conducts a current.... very bright, very effective

Answer 3

Surely Krypton is one of the halogen group of gases.

Answer 4

Bob P's answer is technically correct, however for small battery powered lights on a cycle there is little difference in performance.

Answer 5

I'd go for the ones that are brightest or the ones that last longest, depending on your type of rides. I go regularly mountain biking in the dark but the dilemna between being seen and being able to see has always been a compromise.
Just make sure you can be seen thats the main thing.

Answer 6

Yeah, but how many men does it take to change a light bulb?

Answer 7

Upgrade to HID (high insensitive Discharge light)
i think they use Xenon gas. Much much brighter and use less power. Modification required.
