Cyclops LED bulb adapter

[Ken Tarver]

Cyclops LED bulb in a tourer or standard.
Did anyone use the 1/8" adapter that came with the bulb?
Make any difference, good or bad?

Yep.  Used it.  Didn't help.  Tried w/o it.  Also no help.  Inverted the mount flange.  No joy.  I could not find a position that would focus that bulb.  Or three other designs similar. The problem is, the reflector is made for a tungsten filiment in a specific size and position. 

But the good news is - there are are at least 2 companies making an H4 LED that emulates a halogen H4 bulb pretty closely.  I just got a pair of them in because I knew why the Cyclops and other LED H4's won't focus - I was waiting for someone to make exactly what they did.  Installed it - almost as bright downrange as my 130/90 halogen, but with much whiter light at 6500° Kelvin.  Really pleased, put them in Jade and George.

This is the one I bought:  https://www.genssiled.com/index.php/product/elite-led-headlight-conversion-kit-6000k-bulbs-8000lm/


Watch this video - explains and demonstrates it well:  https://www.youtube.com/watch?v=O8TVgPqy4u0&t=52s

This one looks to be identical, by Phillips, and at ebay for $30 less:  http://www.ebay.com/itm/Pair-160W-16000LM-LED-Headlight-Bulbs-Philips-H4-9003-Plug-Bulb-White-6000K-Hi-L-/142096084883?hash=item2115962f93:g:tzoAAOSwV0RXvWtI&vxp=mtr

The way they rate wattage is confusing to me. One of the advantages to me is the reduced amps of LED's. But are they saying each bulb uses 80 watts ? Or are they comparing the light output to a 80 watt halogen bulb ?

I'd like to see an actual current measurement. The page says 'up to 8000 lumens' and '160LM/W', which means 50W, not 80W. If 80W, then they would be 100LM/W. At 50W the current would be close to 4A, while 80W would be a little over 6A.

It's not clear to me either.  Also not consistent between companies.  I note they talk about all the lumens a bulb could deliver if all the emitters where on at once - but they aren't all on at once. Also it's not clear what is in the regulator module. I note the heat sink on the inside end of the bulb does get warm to the touch.  I didn't check it after it was run for some time to see how warm it gets, but only had my hands on it while I was aligning the bulb to focus it. The warmth implies watts getting used.  I did not put the light on a meter to measure power draw.  I wasn't real concerned with that at the time because both bikes I put it on have my high-power headlight relay mod which can deliver much more power than an LED bulb could possibly use.

The regulator module is a constant-current source, so the LED elements don't get more or less current when the battery Voltage changes; note also that it will work on 24V systems.

Yep, I think those $39 buckers I found on eBad

may be the ticket for Interstates as well.  

I say this with some hesitation as the last inferior LED bulbs I tried on my IS had inside the bucket fans.  Easy install, but they burned too hot and started spiderwebbing my reflectors.  Went back to the best halogens I could find, Philips +130 H4.  They are a good bulb, but only burn up to 450 hours.  Pulled the trigger on the above bulbs, received today.  With a little cussing over placement of the voltage regulators, I got both of the new Lumiled bulbs in, even using the OEM dust covers -- the cooling fins unscrew so you can install them outside the dust covers, exposed to fresh air.  Hopefully that will be enough to keep the bucket cool.  I really like these bulbs.  They're adjustable, they don't require a fan and they are hellishly bright.  I'm still seeing spots!

I tried those and was getting a dead spot in the center. Went with a LED that has lights on 3 sides, kinda a triangle. Much better lighting and no dead spots. On bright they light up signs 1/2 a mile away. Even during the day in noon sun the light up stop signs.

Nope, no noticeable "dead spots" with these bulbs.  That's their main selling point, they replicate the halogen pattern almost to a tee.  Plus they are angle adjustable.  Yours may differ, but many "360 degree" LEDs bleed light, often into the eyes of oncoming traffic.  Check the YouTube video in MarkTs post above.

That was just my experience with them, they may work very well for you. Just didn't suit me.
