is it Lucas wiring?raggedy1 said:has anyone tried the 65w +80% bulb? just wondering how much extra heat is generated and whether our wiring and housings can handle it. i'm not too worried about the wiring as much as i am the housings (10 extra watts should be handled by current wiring, right?).

Daniel Stern has a long article against PIAA bulbs where he goes on to explain how you cannot get 85 watts of light out of 55 watts. He really trashes PIAA.
So what's the difference when Osram claims to get 50 percent more light out of the same 55 watts compared to a standard bulb???
I've used PIAAs in the past and was always satisfied. Stern claims "I" was being fooled by the different color temperature produced from a coating, and that this different color has me thinking I'm getting more light compared to a standard bulb. Well I've used PIAAs in 3 different cars (3 different types and grades of PIAA bulbs and they never had coatings that I could detect) and was always satisfied that they produced more light than stock bulbs.
So now I'm using Osram Silverstars in my Elise. I believe they produce more light than stock bulbs. So how can Osram produce 50 percent more light than the OEM bulb? Is is because the bulb/filament is more efficient?
Ok, I'll buy that theory. But if it's true for Osram, then why can't PIAA be producing a more efficient bulb???
I've spoken and had email exchanges with Stern. He is very opinionated against PIAA and HID retrofits. He practically belittled me for using PIAAs in the past!
just some late night thoughts....
Because some of that is marketing. They produce 50% more than some "legal" lights. There is a range of allowable light that can be generated. Osram SilverStars are manufactured to tighter tolerances to produce at the very high end of the allowable range - which can be 50% more than the light of a poor bulb that's at the low range.raggedy1 said:So how can Osram produce 50 percent more light than the OEM bulb?

I've seen the blue-coated bulbs, and all they accomplish is filtering out some of the colors from the useful light.raggedy1 said:maybe early PIAAs were coated blue - back when this whole blue light/hid thing hit the market? I remember seeing some blue PIAA lights but don't know for certain that they were accomplished via a coating. I'll assume they were since that's what Stern accuses.
TimMullen said:For those wanting better lights for their Elise, and but not wanting to go the HID "retrofit kit" route:
I recently bought some Euro spec Osram SilverStars from a vendor. I bought a pair of H1 and a pair of H7 bulbs to replace the stock bulbs in the Elise. I worked out a deal and got both pair of bulbs and shipping for $65. I asked the guy (Peter) if he was interested in making the "special" pricing (it's lower than I found anywhere else) available for the rest of the Elise forum members, and his response is listed below:
I propose several options:
1. $65 Osram SilverStar +50% more light duo H7/H1
2. $63 Osram cool blue* 4000k H7/H1
3. $72 Osram SilverStar H1, Osram +80% 65 watt H7, 2100 lumen
*The Osram cool blue 4000k is the euro version of the US spec Sylvania SilverStars (blue bulbs).
I would like to have money orders. If people want to do pay pal, please add 2.50 to cover their fees.
Obviously I got the first option (option 1), but option 2 could be chosen by those that want the blue color (but less light), and option 3 sounds like it might good for anyone wanting to push the wiring a bit for the extra light.
If you are interested, contact Peter at [email protected] (website - coming couple of weeks - www.mckeige.com ) and let him know that you read it on the Elise List.
I'll post pictures of the light output compared to stock when I install them (hopefully this weekend).
Your right it's the same low beam and a 65 watt high beam in place of the stock 55 watt bulb.Steve said:Option 3 is the Option 1 low beam with a higher wattage high beam, right?
Did you do anything to beef up the wiring? Or is the higher wattage not a concern?
My car is sitting out the winter, so I'm not in any hurry, but I do want to do something about the lighting.
An increase from 55 Watts to 65 Watts is a only 10% increase by my math. As for the heat, I will be keeping a close watch on the housing. No problem so far!Ground Loop said:The plastic housing, however... I'm not confident it could dissipate enough heat to handle hotter bulbs. A 50% increase in wattage could be more than it can handle, especially with the car standing still. All the metal parts are fastened to the clam, so there isn't a lot of metal there for a heat sink.
