The ultimate light bar series

For nearly a decade, the STEDI name has stood for cutting-edge design and market-leading performance. The ST3303-PRO is a culmination of everything that has made it the globally distributed, sought-after brand born in Australia.

Undoubtedly, the ST3303 PRO is at the pinnacle of the STEDI range. A pure expression of capability and design, combined with brutal performance, makes the all-new ST3303 PRO unmistakably STEDI.

A completely new performance range

Every good story begins with CREE LEDs. That's why we commissioned CREE's XPL HI emitter, which represents a 9% increase in lumen output at the same drive current over the previous model's already great (but now aging) CREE XM-L2. 9% doesn't sound like much, but the key point is that the emitter die size drops from 5 x 5 mm to 3.5 x 3.5 mm. Higher lumen density from a denser source improves the optics-to-emitter size ratio—we effectively increased the optical diameter by 40% without physically increasing it. The result is a massive volume of light and tremendous radiance.

Are you sitting up straight?

Where others stop, we begin. The current appeal is enormous, and quite literally unlike anything else on the market. The 60-LED version draws 36 amps at 13.6V and 40 amps at 12.5V. Do we have your attention yet? Now, without exception, we repeat, you must use the heavy-duty, double-fused wiring harness with two relays (yes, two relays!) that we include with the light. The current is so intense that 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 to handle the enormous current draw.

YOU SHOULD NOT BUY THE ST3303 PRO

It's our most expensive light bar ever produced. You'll have to spend extra money to order a pair of high-quality sunglasses or a welding mask to safely use this light bar at night while driving. If we're being honest, nobody needs a driving light with this level of performance. We only made it happen because the LED geeks on our team insisted, "...it would be pretty damn cool." The type of person who buys a light bar like this has a very strong lighting fetish and thinks it's appropriate and fitting to have to drive a Cummins 6.7L. If you've ever had the privilege of witnessing the performance of our other bars from our lineup, like the ST4K, you'd probably say, "Why on earth would anyone need more light than this?" Well, the ST3303 PRO is just that, more.
