Cyclops H4 LED Headlamp Bulb PREWORD: This review is of an old model LED that is no longer sold. Reach Cyclops Directly: Cyclops Performance LED Vendors thread http://advrider.com/forums/showthread.php?t=839163 www.cyclopsadventuresports.com 1-800-624-0278 Introduction: Let me begin by saying I'm not affiliated with Cyclops Adventure Sports nor any other vendor. I am simply an average guy installing and reviewing this product. I had high hopes for this LED bulb. I first learned of the Cyclops product via ADVpulse.com. They ran a fairly extensive review here and did a great job of capturing how it can improve the stock KTM lighting in the 990 Adventure model they tested with. I decided I would reach out to Cyclops and see if I could get a test unit for both of my motorcycles - Honda CB500X & Honda CRF250L. After an initial email response from Cyclops I did not hear back from them. I decided I would risk the coin out of my own pocket and purchased a H4 LED unit a few days later for testing. Total price was $63.59 with a $6.00 forum discount and $9.64 USPS shipping. I selected normal USPS shipping and assumed I wouldn't see the LED for at least a week. To my surprise it was here in just a few days. Impressive! You can tell this company really takes pride in their product even before you open the box. All of the packaging had the appearance of a top-notch product. Attention to detail was quite evident. Inside the box more of the same. A rather complex LED bulb system with integrated fan and slick wiring harness is very tightly secured inside foam packaging. You also get some generic paperwork and a slew of H4 adapter plates. Prying the bulb from the foam you feel it's dense and reassuring plastic shell. Anyone who's changed a halogen glass bulb knows it's a procedure straight out of a bomb defusing movie scene. The Cyclops LED bulb softly begs you to try to break it. I restrained myself. Stock Halogen Bulb: I had to make do with what I had so setup in my "dark" garage. I decided to initially install the Cyclops bulb in my 2014 Honda CB500X. The motorcycle was on its centerstand with the headlight 8ft 10in from the wall. This was as far back as I could get it. The top of the stock halogen pattern was measured at 2ft 10in from the ground. The temperature(color) is approximately 3000k-4000k (yellowish). Light output is refined and exactly where the Honda engineers intended in terms of seeing the road but not blinding oncoming traffic. You can see the light is being emitted from the top of the reflector section (low beam). Cyclops LED Bulb: First you need to remove your stock bulb and figure out what adapter plate you need to utilize on your LED bulb. A quick side by side comparison told me which to use. Using a philips head screwdriver, you remove the metal base on the bulb for shipping and reattach the adapter plate needed for your application. Now you're ready for installation. The Cyclops LED bulb is hefty. It took some time to figure out how to wrangle the bulb into the CB500X's housing. There's little to no room between the forks and the bulb's home. To complicate matters you have to slip the wire spring in between the fan and the bulb plate while making sure everything lines up just right. It took several tries but I eventually had everything in place. Next, you need to cut the stock rubber boot to accept the new fan assembly sticking out from your LED bulb. I made short work of this with a utility knife of the sharp variety. The whole procedure took maybe 30-40 minutes. Truth time. I turn the key to see what kind of daylight this thing can artificially muster up. I'm impressed and let down all at the same time. The light output certainly seems increased but the beam is nearly 2ft higher from stock position and doesn't spread like the stock halogen does. This is exactly what I feared. From reading other posts, and looking at photos of other installations, it appeared to me that the Cyclops LED bulb was aimed far higher than stock bulbs. This helped give the impression that there was more coverage from the light. Also, the temperature(color) is definitely higher, probably around 5000k-6500k(white/blue). It gives the impression of a HID bulb. My best guess is that the LED units also push light across a portion of the lower reflector that creates the high-beam effect. Edit: Confirmed that this bulb doesn't line up correctly with the factory reflector and does reflect off both low and high beam sides at all times. The Cyclops LED bulb pattern doesn't have a clear cut-off. I approximate the top of the pattern between 4ft 2in and 4ft 9in. This is almost exactly 2ft higher than the stock bulb pattern. The Cyclop's pattern also appears biased to the left and a bit more narrow. I'm unsure if it's due to me installing it improperly or perhaps manufacturing quality control. Here's a quick side by side comparison of the stock pattern vs the Cyclops pattern. You can see the stock pattern extends right past the electrical outlet on the passenger side and goes well beyond the driver's side piece of tape. In comparison the Cyclops pattern is more center oriented not reach as far driver or passenger side. It's also fair to note that the white-balance and exposure are higher for the stock bulb because the Cyclops bulb was so much brighter. After adjusting the CB500X's housing down as far as it would go I still couldn't get the pattern to meet the stock height. I believe it's close enough that I won't severely blind on-coming traffic but I fear I've ruined the advantages of the LED bulb now. Fair to once again note that this system is sold for off-road use only and isn't approved by the Department of Transportation for public highway use. Judging how the Cyclop's LED beam appeared after a direct swap and no adjustment I can certainly see how it could help an off-road application. I look forward to taking the bike out after night fall to see how variables have changed. The CRF250L and CB500X share the exact same headlight housing so I plan on standing them next to each other for an impressive side-by-side comparison. More to come!
