Review on 💡 High-Performance KATANA LED Bulbs, 12000LM 72W 6500K, H11 H8 H9, Conversion Kit with 360° Adjustable Beam Angle – Halogen Replacement by Jim Escobedo

Another reviewer pointed out that this is the same as the highly acclaimed (and very expensive) Supernova SV4. These are excellent quality bulbs with a consistent and superior beam pattern, MUCH brighter than the original. I can confidently attest that they are indeed the same. I've been using SV4s for 2 years and one of my bulbs has blown (mostly I use them during the day so I spend more time with them but I still expected longer life). I know there are a few models (probably about 10) that perform better than my 2 year old models, but they've been great for me, and these newer models from other manufacturers are MUCH more expensive (typically $150-200 dollars), so I decided to give them a try based on reviews from other reviewers that they are identical to my current SV4s. Thanks to him I saved a lot of money. As they are the exact same bulbs, harnesses, cables etc, they offer exactly the same performance that I've come to expect from the SV4. These are BIG lights that give a much better and easier view at night while driving. I have a deeper field of vision, a wider field of vision, and much more intense lighting around me. At the same time, the radiation behavior is excellent, so I don't dazzle other drivers. It has an accurate limit cut-off with no leakage, which is usually the case with cheap lamps. They are dangerous as they make blind drivers. There are no problems with katana. Can't comment on durability yet, but if I can get the same 2 years or so for 1/4 the price I'll be very happy. If you are looking for a lightbulb with excellent performance at a very reasonable price, buy the Katana.
