Yes Jer, the led on top lights up the upper reflector which is reflecting downward, and the bottom led reflects on the bottom of the reflector which will reflect the light upward. Hence high and low beam.

That's pretty awesome! I wonder why these brighter bulbs aren't in the motorcycle kit? Wonder if they would split the package?

I was going to go for the Xenon projector fitment as another member did, but I like that given the single-bulb nature of the bike, I can swap the LED for a regular bulb should anything go wrong..

I take it this is what you're thinking of installing? And the fins on the back, I assume for heat disapation is what you're concerned with? Or am I looking at the wrong bulb? I'm not sure that 1800LM on high beam is that much more then what we have.
Think there is clearance for them cooling fins?

I was going to do that too, I did that to my old bike was a lot of work but worth it, I did dual bi-xenon projectors, made my own custom harness. 35w 4300k HIDs that put out 3000 lumens each. Now I'd rather just put these new bulbs in and have no ballasts to worry about no harnesses etc. It puts out more light, uses less energy than the stock bulb and it's plug and play. Sure the heatsink in the back is a little big, but I'll figure out what to do when the time comes or if someone orders one here and installs one before I do.

The bike LEDs from Lifetime are lower wattage than the automotive units. They have a plain heatsink, the auto ones have a fan in there too.

So, I'm not sure that the H4M would be bright enough. Certainly not as bright as that pair on a Toyota truck. Wonder if the regular H4 would fit in the Strada headlamp housing?

Actually I'm tempted to get a set for our Mazda 3 - but it looks like I'd need two pair. Ouch.

Found something else interesting. A manufacturer of LED bulbs was doing a test between halogen, LED and HID in reflector and measuring the effective lumens to the ground/wall.

"A halogen bulb, 22w LED headlight bulb, and 35w 5000K AC digital HID kit were placed and tested in a reflector housing headlight assembly. The same light meter was capturing the halogen bulb at approximately ~650 lumens, 22w LED headlight bulb at ~1200 lumens, and the 35w HID kit at ~1500 lumens. "

These kits that LifeTime has definitely has HID range of lumens to the ground.

Ive just been surfing a researching. You can find some reviews of these lights on off-road forums and elsewhere. Nothing but positive reviews! All say much more light than halogen, and that is has the same cutoff as the standard bulbs, so no blinding people or getting flashed at.

However, all are using standard car kits, not the H4M..

So what's the deal? Does the H4M bulb from LifetimeLED fit?

Also, if the bulb is sealed airtight in the headlight housing, where does the heat go that the heat sink is dispersing?

I was thinking of getting the HID retrofit kit, but that's at least $150 plus install costs so this would be a lot cheaper and easier.

When I look at test results I always consider the source (aka 'follow the money"). What wattage and make of halogen bulb did they test? Very convenient that they left that out.

My searching shows a standard 60/55 H4 bulb with ECE approval is rated at 1650/1000 lumens, the DOT version at 1590/980. "High efficacy" versions are available with the same watt ratings, up to 1895/1148. I note that DOT certification would include these lumen outputs. The manufacturer is responsible for testing, but if they are found to be cheating it can result in a safety recall.

If that's not enough, you can go up a few watts to a "Rallye" H4 at 70/65W without changing the wiring, giving 2000/1350. There are even more powerful versions, but they carry "Can damage plastic lamps" warnings.

The Lifetime H4M is rated 24/18W and 1800/1400 lumens. Sounds like quite a bit of work for not much benefit.

OTOH...I'm a retired mechanical engineer, and one of the sayings I've learned to believe is "Specifications are lies made up by marketing departments!"
