H4 conversions, 5.75" Rounds revisited once again

[txrocco at sbcglobal.net (Patrick Bureau)]

Yes I know about those, I beleive Ben Harper has demonstrated those light
last cincy they are just awesome.
I am investigating some of those, found some 12/14v 35w landing aircraft
lights (5.75") producing MEGA light..

->In the 70's my friends used to swap their high beams (round) with
->aircraft landing lights.  Amazing they were about the same size
->but you didn't want to be looking at them when they were turned
->on.  I don't know where they got them from.

->Im my continual search for the lenses that will be handle to
->handle my 100/130w H4 and 100w H3/H1 Rallye Bulbs, here are some
->revised and new results. My testing has been based on 2 types of
->Headlights, Round 5.75" and Square 4x6" as well and the result I
->enter below Applies as stated by type tested.
->
->Stay away of the following lenses if you are running anything
->above 55/60w bulbs
->
->Crystal Headlight series
-><http://www.streetbeatcustoms.com/sealbeamcon.html> (4x6 & 5.75"
->lenses), the reason being simple, at 100w continous use, the
->polymer casing though a thickness that should handle a lot of
->heat, and the polymer lenses that I had hopes would resist
->chipping and cracking from road hazzards, turned out to be weaker
->than expected at true high wattage lights. after 3 weeks use the
->inner polymer ring holding the flat edge of the H4's simply
->cooked and burned slowly, imagine cripsy burned black plastic. I
->rate it a 2/5 , because fitting was less than perfect, and beam
->pattern seemed to diffuse the light everywhere more than on the
->road after 30 meters.
->
->The JC Whitney have a replacement H4 Glass and Metal housing
->Lense,(5.75"
->Lenses)<http://www.jcwhitney.com/webapp/wcs/stores/servlet/Product
->Display?catalogId=10101&storeId=10101&langId=-1&productId=234753&m
->ediaCode=ZX&appId=385869> had hopes about this product as well,
->and would reccomend it for a standard 50/60w application, the
->glass lense has a decent pattern on the road, and is a great
->upgrade fversus the Sealed beams, the look remains stock, and I
->liked these alot as they fit like a glove, unfortunatly, the
->lense curvure being identical to a seal beam, and the H4 being
->longer in lenght than a sealed beam bulb, this places the hottest
->point of the bulb (tip) the closests to the middle point of the
->lense. and yes you guessed it with 100w/130w bulbs, it took me 2
->days to crack both lenses in 2 parts.
->I rate this product a 3/5.
->
->Peter Scirocco, A List member was selling used 4x6" lenses for
->H4's, product I jumped on , as the price was more than fair but I
->was and remained a little dubious at first, the makes of the
->lenses I has never heard of not could produce any real
->information on the companies that mmade them, I expected them to
->fail, as I have been starting to beleive that I was not to find a
->cheap solution. Wel the lenses were "Maxtel" and "Cluteroche"
->this last one made in france, impress me a little more confidence
->as we all know europeans use true wattage bulbs not 50/60w that
->try to produce X amount of white light to imitate 80w bulbs or
->higher. Well I give these 2 makes a big 5/5 they resisted my
->100w/130w bulbs without as much as a twitch.. the patterns we
->very good, a really good upgrade on the 4x6 sealed of the
->Scirocco MKII's I give these lense 4/5 simply top notch generic
->lenses. Peter do you still have some more ??
->
->Hella 71456/71156 Lenses (5.75"), expensive, but impressive,
->their design as signature of engineering, bought a new set off
->Ebay for 150$ (2 H4's 2 H1's), the first things to notice is the
->steel, much thicker at the eyes view, the casing being much more
->polished in finish than others I have seen so far, Their
->lenses... Well I know why their lenses can sustain the heat of
->the high wattage bulbs I have... they simply use a flat lense
->that is actually "Spaced" out from the metal casing thus the
->front lense is about 1/2" father out front... permitting it to
->remain cool even under the heat of high wattage bulbs, Yes I know
->many may know or not know this, and now will be in the
->scirocco.org archives to be found :) easy rate this a 5/5. too
->bad their cost is prohibiting, otherwize everyone would have them
->on their cars.
->
->There are a few More I have decided to try, simply because at
->this point I have tried so many of these lense, that I feel
->compelled to continue testing..
->
->more to come on other lenses in the future, looking for those
->(Projector types maybe someone has the web site again?) at this
->time, if someone has them on, a review would be appreciated by
->all I am sure.
->
->cheers
