Silverstar Ultra??

WilliamBos · October 12, 2015

Was wondering how much brighter the Silverstar Ultra low beams are compared to my stock 55W H11?

Have run Silverstars before, but not SSU.

Seemed about 20% to me. But the candle that burns twice as bright, only lasts half as long. Short life wasn't worth it to me. Have since upgraded to LEDs.

Thank you. What are you running for LED?

These for the headlights - superbrightleds LED Headlight Kit - H11 LED

These for the fogs - superbrightleds LED Headlight Kit - H16 LED

They're also about 20-25% brighter, but they should last longer than my Sierra.

+1 on what burbs said.

I run these on my bike and while brighter and wider they burn out relatively quickly.

For what they cost id just invest in a cheaper led light bar and call it a day.

Thanks. How long hsve you been running those LED headlights?

Couple of months. I like them. Have driven in both rain and fog - they work great.

Here's a writeup I did on another board...

Well, instead of tacking onto an alread-long thread, I figured I'd start a new thread for my install. I bought the superbright LED H11 and H16 kits for my Denali. Finally got around to installing them.

Installing the headlights was pretty straightforward. Since this was my first time wrenching on the truck, I decided to rip the whole front end apart. Wanted to get a feel for the lay of the land. No clearance issues. The lights plugged in easy and went on the first try. I used some 3M doublesided foam tape to attach the little "driver" boxes to the vertical fender supports.

I expected the foglight install to be a piece of cake - just crawl under the truck and swap out the bulbs. I popped out the OEM bulbs easy enough, but I couldn't get the LED bulbs to latch in. The bulb would engage one latch, but then it would seat to lock the second latch. I figured out that there wasn't enough room for the o-ring on the bulb housing - it wasn't compressing enough to seat into the foglight housing opening. The o-ring groove wasn't deep enough, so I took my Dremel with a thin cutting wheel and whittled the groove to give more room for the o-ring. Once I'd ground down the o-ring grooves a little, the bulbs seated right in and engaged both latches.

So how do they perform? Well, as you can see in the pictures, the lows don't have that sharp cutoff like the OEM halogen bulbs. So I guess I'm now one of those pricks that's blinding oncoming drivers. That being said, I've yet to be flashed by any oncoming traffic.

Light output is probably 25-30% greater than the halogens, and the color is much better. The foglights are easily 2x-3x brighter than the OEM bulbs, but I think the crappy OEM reflector housing keeps them from being truly brilliant. They do throw out some pretty good peripheral light.

Overall, I'm happy with them. I would recommend them, assuming they last as I expect them to. I got these LEDs because the Sierra uses the lowbeams as DRLs. I didn't want to install HIDs, because I know they don't like the constant on/off they'd see in the Sierra. I have HIDs in my Suburbans, and I love them. I'm probably going to pick up another pair of the H16 bulbs to install in the fog lights for my '08 Suburban.
