Hey does anyone know if the standard alternator in a 1989 Suzuki sierra be ok to handle a led light bar? |

Yes it should have no problem, what size are you looking at? |

I'm tossing up between 2 x 4" or a 500mm bar. Not 100% sure yet |

Okay awesome, you're alternator will have no problem running them. Check out klutched website if you're interested, he's got a good range. viewtopic.php?f=15&t=36987 |

I just installed 2 x 6", 30w (3x10w) for a total of 60watts. thats only an extra headlight. Although I did run them thru a relay, I probably didn't really have to. I wanted to run just a single 20" light, but I decided to make sure the coppers couldn't pick on me. |

Sure LED bars are more efficient and use less power for the same light, but, without knowing the power consumption (wattage) of the bar, any answer is just a guess - 500mm - that's a 20" bar, probably 120W, that's actually more than a pair of standard halogen spotties - my guess is you're pushing your luck. |

I wanted to run just a single 20" light, but I decided to make sure the coppers couldn't pick on me. 60W at 12V is 5A - a typical 12V switch is rated at 3A - that's the first reason to use a relay, the second is to eliminate possible voltage drop over long, small gauge cables - or - to phrase that differently, to allow the use of less expensive small gauge cables for the longer runs, with incurring excessive voltage drop. |

+1 to both of Fordem's posts. People get so carried away with the idea that LED's are efficient, and assume they use no power. I recently saw a 240W LED bar hooked up with speaker wire, at the end of the day that still draws 20A. |

I jumped on what I thought was a good deal at the time but after a month of using a 30 or 36w light bar from him I ended up binning the thing. The mounting system is pretty poor, always rattled loose and had sweet F A adjustment; unless the bracket/bar already sits perfectly level, the thing would point either 5m in front at the ground or you'll be forever spotting possums. I recently purchased a better (albeit still Chinese) bar which mount from the outside. It had better light output and a stronger mounting system for a much better price. Cheers, Alex |

Cheers, Alex if people are buying them hes making pretty much 3 times what he paid for them too so your not getting them cheap anyway |
