Cali Raised LED 42" Dual Row 5D Optic OSRAM LED Light Bar
Cali Raised LED 42" Dual Row 5D Optic OSRAM LED Light Bar
A 42 inch light bar is where a lot of builds end up once the owner has run a 32" for a season and wanted more. It is long enough to throw light right across the trail, short enough to fit on a midsize truck roof rack or a full-size bumper without hanging off the ends, and it does not need the mounting width or the electrical budget of a 50-inch-plus bar.
This 42 inch LED light bar is Cali Raised LED's straight dual row model: 80 OSRAM LEDs behind 5D optics, rated at 40,000 lumens from 400 watts, in an extruded aluminum housing sealed to IP68. It comes with a plug and play harness, a switch and mounting brackets, so you are not ordering three more things before you can turn it on.
Where the 42" Sits in the Range
Cali Raised build their dual row OSRAM bars in three lengths, and the useful thing to know is that they scale evenly. Every one runs 5 watts per LED and is rated at 100 lumens per watt, so choosing a length is really choosing how much light you want and how much current you can spare. Nothing else changes.
| 32" Dual Row | 42" Dual Row (this bar) | 52" Curved Dual Row | |
|---|---|---|---|
| Rated lumens | 30,000 | 40,000 | 50,000 |
| Watts | 300 | 400 | 500 |
| OSRAM LEDs | 60 | 80 | 100 |
| Approx. draw at 12V | 25 amps | 33 amps | 42 amps |
| Shape | Straight | Straight | Curved |
| Best for | Bumpers, grilles, smaller roof racks | Midsize roof racks, full-size bumpers | Full-width roof mounts, maximum output |
Against the 32", a 42 inch light bar gets you a third more light for a third more current. Against the 52", you give up 10,000 rated lumens but stay straight, which matters more than people expect. A straight bar fits flat bracket and rack cut-out mounts that a curved one will not, and it sits flush on a bumper.
Need it for dust and fog? If you want a bar around this length but your problem is visibility in weather rather than raw distance, look at our 43" amber and white dual function bar instead. White light at this output turns fog and dust into a bright wall. Amber cuts through it.
Dual Row and 5D Optics
A dual row LED light bar stacks two rows of LEDs in one housing, which roughly doubles the light per inch of bar compared with a single row of the same length. That is how 80 LEDs fit into 42 inches.
The 5D optic is the reflector and lens shape around each LED. Cali Raised's claim for it is a wide radius and longer throw, and the practical effect of a good optic is that more of each LED's output ends up going where you aimed the bar rather than scattering upward or into the bonnet. It is the part of a bar you cannot see in a product photo and the part that makes the biggest difference between two bars with the same lumen rating.
About the OSRAM LEDs
OSRAM is a long-established German lighting manufacturer and one of the big names in automotive LEDs, which is why an OSRAM LED light bar is worth singling out. Naming the LED supplier matters because plenty of budget bars do not, and an unbranded diode can be anything. That said, the emitter is one part of the system. Optics, heat management and the driver electronics decide how long a bar actually lasts and how much of that rated output reaches the trail.
About the 400 Watt Draw
Do the sums before you fit it. 400 watts on a 12 volt system is roughly 33 amps. That is a third more than the 32" dual row, and a serious load in its own right.
- Run it on the supplied harness. Do not tap a 42 inch light bar into an existing circuit because it happens to be near the mounting point.
- Run it with the engine going. A parked battery will not thank you for 33 amps, unless you have a dual battery setup and know your numbers.
- Add it to your total. If you already run a fridge, a compressor, a winch and camp lighting, check your alternator and wiring have the headroom.
None of that is a reason not to fit it. It is a reason to plan it. Give us a call if you want to talk through your electrical setup first.
Why It Keeps Working
Extruded Aluminum
The housing doubles as the heatsink, with integrated thermal management to move heat away from 80 LEDs. Heat is what kills LEDs, not hours.
GORE Pressure Vent
Equalises pressure as the bar heats and cools, so it does not pull moist air in past its own seals every time it cools after use.
Voltage Protection
Over and under voltage protection guards against alternator spikes and a tired battery. Instant on and off, no warm-up.
The lens is polycarbonate, which takes a stone strike that would crack glass. Over years of UV it will haze a little, the same as every polycarbonate lens on the market, and a plastic lens polish brings it back.
IP68, and the Fine Print
IP68 is the top of the ingress protection scale. Cali Raised's rating covers dust, dirt and sand, and submersion to 1.5 metres for up to 30 minutes. Worth knowing: the test condition is fresh water. Salt water is harder on seals and connectors, so if your bar sees beach driving or salted winter roads, rinse it and the connectors with fresh water afterwards.
LED lifespan is rated at 50,000+ hours. In practice the wiring, the connectors and the truck itself will give out long before the diodes do.
About the 40,000 Lumen Rating
The figure is a manufacturer rating, and like almost every lumen number in this industry it describes raw LED output rather than light measured at the trail. Real output through any lens and optic is lower, on every brand. We have not independently tested it, so treat it as a fair way to compare this bar against others rated the same way.
What we can say is that the numbers hang together. 400 watts across 80 LEDs is 5 watts each, and 40,000 lumens from 400 watts matches the rest of the dual row OSRAM range exactly. That consistency is a good sign. Not every spec sheet we see adds up.
The Brackets Are Universal
The included mounting brackets are not vehicle-specific. They will hold the bar, but they are generic feet rather than a mount shaped for your rack, bumper or roof. Depending on where it is going, that can mean drilling, spacing or an imperfect fit.
Measure your mounting location before you order. Tell us your vehicle and where the bar is going, and we will tell you whether the included brackets will do the job or whether a vehicle-specific mount is the better call.

Frequently Asked Questions
Will a 42 inch LED light bar fit my truck?
The bar itself is universal and works with any make, model or year. Whether it fits your mounting spot comes down to space. A 42" bar commonly suits a midsize truck roof rack or a full-size bumper, but measure first, because the included brackets are universal rather than vehicle-specific. Send us your vehicle and mounting location and we will check it.
How many amps does this 42" LED light bar draw?
At its rated 400 watts, roughly 33 amps on a 12 volt system. Run it on the supplied harness rather than an existing circuit, and preferably with the engine running. If you already run a fridge, compressor or winch, check that your alternator has the headroom.
Should I get the 42" or the 52" curved bar?
The 52" curved gives you 50,000 rated lumens against 40,000 here, but it draws about 42 amps and needs the mounting width for a curved bar. Choose the 42" straight if you want flat mounting, a lower draw, or the bar is going on a bumper or a midsize rack. Choose the 52" if you want maximum output across a full-width roof mount.
Is it good in fog or dust?
Not especially, and no bright white bar is. White light at 40,000 lumens reflects off fog, dust and snow and throws glare back at you. This bar is for distance and coverage on a clear night. For weather, our 43" amber and white dual function bar is the better tool, because amber scatters less and carries further through particles in the air.
Does it come with a wiring harness and switch?
Yes. It ships with a plug and play single-leg wiring harness with a standard switch attached, plus universal mounting brackets and hardware. If you want a factory-style switch that fits a blank in your dash, that is available separately.
