I have got Cibie spot lamps fitted in place of my STi 'Covers'. One of the bulbs has blown and it turns out to be 12V 100W H2. I can only find 12V 55W H2's at Halfords and various other places I have tried say that 100 watt bulbs are illegal and that 12V 55W H2 should be used instead (everyone I tied has these).

Does anyone know where I can get the 100 watt version from? Is it worth the bother/cost and would 55 watt versions be adequate for the purpose?

Thanks for any advice.

Both Halfords & Motorworld near me have 100w bulbs..try another store, or different member of staff

 

Demon Tweeks do H2 100w (RU480) and 130w (RU491) Ring bulbs.

 

If they are E marked, they are legal, if they aren't, they aren't

Bulb wattage is not linear to lumens output. A 100w bulb probably only puts out about 10-15% more light than a 55w. The extra brightness comes from running a thinner filament which burns brighter, but the downside is they have a shorter life expectancy because of this, and are more subject to vibration failure.

The spring clip type bulb holder Cibie use with the H2 bulb is a poor design and exacerbates these problems.

 

Do you know what bulbs do the PIAA kits use Dave?

 

PIAA use H3. Spade connector wiring connection, much better than H2. You can get 130w H3 bulbs from Halfords

Don't know if they are E marked, and don't care

 

Having tried all the local Halfords and other car accessory shops without success, I finally ordered a 100w H2 from Demon Tweeks. Naturally, I shall only use it during 'off road excursions'!

Thanks for all your input.
