If the question is what is the upper limit - Its not a straight forward answer and depends on a lot of factors and use cases here. Bottom line - 145/100 is seriously an overkill even if that thought has crossed the mind. Last edited by paragsachania : 20th August 2014 at 20:58. | |

| ![]() 145/100 is going to generate a hell lot of heat which wont be good for the headlamp components. New relay and wiring kit wont be enough. There are other components in a normal headlamp that will not take such high temperatures, resulting in many problems such as reflector coating damage, smoking of headlamp lens from inside due to fuming plastic components, ruining the headlamp on the long run, etc. These damages are definite. But on the short run he wont face these problems. About upper limit, it depends on the tolerance and durability of the headlamp assembly right. So it's hard to say unless tried and tested in that particular type of headlamp. But anything above, say 80 watts is going to heat up the electrical terminals so much that it increases the resistance of the contacts which reduces the efficiency of light output. So there is no point adding so much more wattage unless for special purpose (not normal road use) in performance lighting components (not stock headlamps). |

| ![]() And one more important fact is that cost of bulbs + wiring + relay etc are all within 1500-2000 range, but one set of reflectors, i.e Headlight assembly kit will amount to 7000 to 10000 depending on the car. So the obvious fact is that you should stay away from damaging your reflector's chrome insides, even at the cost of foregoing some brightness. Or like some experienced night drivers suggest, go in for Hellas or Rallye auxillary lights on the bumper if you are adamant on blinding the opposition. |

Upper limit depends on what the manufacturer can produce, and that wattage of a bulb which can run without failing early or exploding, which depends upon materials. Till today I knew that the max one could get was 140/100 from GE. Today I came to know of 145/100. This is definitely not required IMO even in the worst conditions. As mentioned by manufacturer, this is best suited for off road use where conditions may be pitch dark and the obstacles can be totally unexpected. On the road, these bulbs are unsafe, unreliable as well as unnecessary. I think straight6 was casually asking about the same. That bulb will fry the altos alternator. |

| ![]() Well I don't think the 20-30 extra watts are going to have a drastic effect on the system compared to the 130's. Besides, in all the years of using these bulbs I've learnt that you can preserve the headlights and maybe others components by not using the headlights when not required. There's no need to use them when the road is brightly lit with street lights, at stop lights or even until its really dark in the evenings. I see a lot of people with their lights on when not really required. Also, if you use the high beam wisely it helps a great deal towards preservation. By the way, I've now got the SX4 Zxi and it comes with cover in front of the bulb so I'm guessing it will help. The Flosser bulbs are not available in India I think but the GE are available on Ebay.in and so are the Bosch 130/100 for half the price of the Philips for a pair.

| ![]() Can someone give an idea about the heat generated in Celsius by a typical 100/90 bulb ? I am not asking about the filament temperature which would come around some 2500 C or more. What I am interested to know is the temperature of the bulb base area metal part which contacts the holder. The reason why I am asking is because I saw this LED angel eyes on ebay which directly fits on H4 Bulb base by double-sided tape. Ebay Link: I was wondering how long the tape would hold on to the base of a 100/90 bulb without melting,since the bulb can get quite hot within a few minutes of usage. Or is there some special heat-resistant tape they may be using which may not melt easily on the hot bulb base? Last edited by VinodDevil81 : 21st August 2014 at 19:39. |

| ![]() The SA mentioned that my Figo's right headlight along with the bulb was damaged in a recent accident. Now, I'm left with a 4 month old single OSRAM H4 nightbreaker plus headlamp. I've searched everywhere online but I'm unable to find an option to purchase a single bulb instead of the usual pack of two. Can anyone guide me where I can find this in Bangalore? And is there's any difference upgrading to the OSRAM Nightbreaker Unlimited bulbs instead. |

| ![]() Guys, is a bulb upgrade possible for the rapid. It has projector low beam and normal high beam. Pls suggest. |

BHPian ![]() | ![]() Here are the pictures of the new headlamp cluster on my Estilo. ![]() ![]() ![]() Sorry for the delay guys! No doubt the throw and focus of the light is proper now. The confidence of driving at nights has gained steeply! Have switched to Philips Xtreme Vision from Philips Rally 90/100W. Hope they don't burn the reflectors now! The old ones had become a joke! ![]() Last edited by nishantdlv : 23rd August 2014 at 01:19. |

No question of burning the reflectors with Philips XV, but these bulbs have a shorter life than normal halogens. So you may keep a spare set in case you travel out of town and do night driving. | |
