Wattages

What is the wattage on your main front light? If you have a high and low beam option, select the high.

I'm asking this b/c I've set up a 20 watt system (or am setting it up). I have two casings so I'm thinking about having a 50 watt that'll remain off until I'm in need at a bright intersection or something. Can't see me? NOW YOU CAN'T SEE ANYTHING!!! (muahaha)

Most of the common wattages for bulbs fit into two categories. I use a 10W halogen when I commute in the winter; is that 5-10 watts or is that 10-15 watts? Since it's an SLA system that loses brightness as it discharges, I picked 5-10 watts.

50 watts will blind drivers if it's not aimed carefully, and I shudder to think how quickly it'll burn through batteries.

Yeah I switched from 15W (2 categories) to 20W (also 2 categories). If I vote for the middle category I'll feel like I didn't really 'upgrade' my light!

I still wonder about 'effective' wattage too. Dyno people will tell you that 6W aimed along the road will give you better vision than 20W aimed through the air, you know not where. That could be true.

And then there's LED or HID 'equivalency'

Wattage will not tell you how bright a light will be. Wattage it the rate that the power it uses.

I have twin 20W halogens controlled by a lightbrain. It gives me 7,10,20,30 and 40W with the flick of a momentary switch.

The man wants pictures.

Here's some quick pics:

5036. The battery box with innards.
5045. Brake switch
5047. Front lighting arrangement.
5048. Rear lighting arrangement.
5049. Battery/electrical box
5052. Switches. Light/off/horn and LTS/off/RTS

It's too crowded in the garage to get good shots and it's too cold and dark outside right now to get better pics.

I'll do a full workup on how I built this lighting system last December and post the PDF in my signature as soon as the semester ends. I'm busy busy busy busy for about three more weeks.

Yes, it has a keyed master on/off switch. It helps keep curious people from playing with the lights/turn signals or accidentally bumping the switches and thus, leaving the lights on til the battery runs down. It also helps to keep an old doofus like me from forgetting to turn the lights off.

Dinotte 5W LED mounted on the bars, supposedly equivalent to 12-15W Halogen
I also have a 3W Dinotte LED on my helmet.

Two Optronics Housings - one with a 20w halogen for the pitch-black rural portion of the commute (when I need to see), and one with a 20LED MR16 for the streetlight portions (when I just need to be seen.) Running the 20w for the entire hour and a half commute was really killing my 7ah SLA battery.

A 20 W flood, a 15 W spot, a 20 W spot and a 20 W spot on my helmet. 75 watts. I've go another lamp so I could add another 20 W but that would be silly

I'm all over the place with this one... but usually it's the 10-15W range -- LED. Really, you cannot compare wattages... that's a unit of power, not of luminance. And the supposedly equivalent claims are laughable.

That is a kool setup! I was thinking of getting one of those extenders so I can mount multiple lights on it. Although I don't think that particular one will fit on to my handlebars.
No idea how many watts my light is. It is very visible thought, and painful to look at directly from 50ft away or so.

10W hi beam, 6W low beam. I generally use the 6W more than I do the 10W though.
