Stedi ST3303 23.3" Double Row HP

We conceptualized a light bar that would be diabolic, something excessive, over the top, a real savage. Then, we went ahead and made it. No other light bar on the market encapsulates 32 x 10W CREE XM-L2 LEDs inside of 21.5” housing – A world first then?


 For almost a decade, the name STEDI has stood for cutting-edge design and market-leading performance.  The ST3303-PRO is an aggregation of all things that have made us the globally distributed, coveted brand born right here in Australia.

Unquestionably, ST3303 PRO sits at the pinnacle of the STEDI offering. A pure expression of capability and design that converges with brutal performance, making the all-new ST3303 PRO unmistakably STEDI. 

Registered Design: 201915829.


Every good story starts with CREE LEDs. So, we commissioned CREE’s XPL HI emitter, which represents a +9% increase in lumen output at the same drive current over the already great (but now aging) CREE XM-L2 found in the previous model. 9% doesn’t sound like much, but the kicker is that the emitter die size drops down from 5 x 5mm to 3.5 x 3.5mm. Higher lumen density with tighter source improves the optic and emitter size relationship – We’ve effectively increased the optic diameter by 40% without physically increasing it. The result is a huge light volume and tremendous beam throw. 


Where others stop, we get started. The current draw is enormous, and quite literally unlike anything else on the market. The 60 LED variant draws 36 amp at 13.6v & @ 12.5v 40 amp. Have we got your attention yet? Now, you must, without any exception, we repeat, you must use the heavy-duty, dual relay (yes dual relay!), dual fused wiring harness we supply. The current is so intense, the 40 LED and 60 LED bars have two separate power cables (yes two separate power cables!) on either side of the light bar, and two separate breathers (yep two!) to deal with the enormous current draw. 


Commission your own striking colour combination with our customizable side caps. Grey and STEDI orange caps are included, and when you get sick of those, green, blue, and red are available to purchase separately. 


It’s our most expensive light bar ever produced. The price is right up there, and so is the performance. You're going to need to spend more money to order a pair of high-end sunglasses, or welders mask so that you can safely use this bar while driving at night. If we’re being honest, no one needs a driving light with this level of performance. We only made it because the LED geeks in our team insisted that: “ would be freakin’ cool”. The type of person that buys a driving light like this has a very strong light fetish and thinks that dropping a Cummins 6.7L in a Daihatsu Charade is adequate and appropriate. If you have ever had the privilege of witnessing the performance of our other bars in our range like the ST4K, you’d probably say “Why on earth does anyone need more light than this” – Well, the ST3303 PRO is precisely that, more.
