I Just checking to see if any one is using the 100 watt halogen H7 bulbs in the low beam? I would like to know if the reflector and socket can stand the extra heat created by the 100 watt bulbs long term or will they melt?
I currently have the 65W rally bulbs. As far as the electrical side is concerned I can get the ceramic connectors and larger wire, I am not worried about that just the lamp its self.


PS, as some of you know I installed Piaa 85W H3 in fogs, they melted $320. lesson on what not to do.

DO NOT USE 100W BULBS!!

Check out Daniel Stern Lighting Consultancy and Supply for info... especially check out the 65W Osram Ultra High Output (2100 lumen, H9 burner on H7 base, race and special-purpose use): $29.40/ea

They are bright and do not cause excessive heat or power draw... no modification needed

100 watts is kinda weak, man. I bought two football stadium lights and mounted them on my Merc. I was dissapointed so I ordered the W5000 Illuminator Blaster (the same shit mounted on Enterprise). The light is so powerful, it circles the earth and i can see the back of my car on a small screen (included). Oh, ya, and they give you a pair of night goggles as a gift.

91 300CE,

I have the 65 watt Oshram Rally bulbs in the car now, as I stated in my first post. I am just looking for anybody that has tried the 100 watt bulbs.

You say "DO NOT USE 100W BULBS" and offer no reason, I am after the answer to the question. What happens if you use 100 watt bulbs in your low beam, long term?

Hey, YM.

+1 on the lens polishing, if yours have some glazing/fogging that will make a world of difference.

I have not used the 100 watt units on the 210, but my last car had pretty poor lights and I put 80/100 DF bulbs in it. The hotter element burned out more frequently and light output was only marginally improved, sort of how a magnifying glass helps reveal flaws; brighter is not always better.

If I were looking for more light on my MB I would replace the entire units with factory xenons or quality depo conversion projector units. If you really want to pursue this path of brighter H7s you could try the xenon ballast kits that are on the market, they operate at are lower temp than stock and if you get a lamp malfunction warning you can add a resistor to the circuit. I have a friend who imports some of the better quality kits for his side business, they were an improvement on his X-box but I have come to appreciate that in this arena quality of light is more important than quantity. That said, I suppose that would be a relatively inexpensive experiment. ;)

Take care and enjoy the ride,
Greg

Sorry... didn't fully read... lol... I pasted the link to DS Lighting for explanation of why not to use high wattage bulbs.

Is that all, My assumption as to "fry the housing" means the bulbs socket and reflector will get hot enough to melt the outer housing, and probably the parts that hold the reflector in as well, true? I am at a point of indecision, with many possible solutions.
I would like more usable light (my W211 bi Xenons have spoiled me) and the HID conversion on my fog lamps is out performing my 65 watt low beams. The options I have are.
1. install 100 Watt bulbs $50
2. install 35 watt HID kit $150
3. install used OEM Xenon $500
4. install Depo w/E55 projector $850
5. install Depo w/E55 bixenon projector $1100
6. install new oem Euro xenon $1600

My lenses are in show room new condition car has 29k and has been outside less than 90 days. I hacked my fog lamps when the piaa 85 watt bulbs melted, you can see first generation hid fog here, http://www.benzworld.org/forums/test/1328919-99e430s.html
Second generation, new lamps and shorter bulb greatly improved the fogs.
Now, I would like to upgrade the low beams, what I want is new Euro lamps but that is more than 10% of the cars value so before I do that, I'll gladly burn up what I have.
