Looks like they're getting 20Watts for 800 Lumens and 50Watts for 1700Lumens

I know that the headlight bulbs that were in my Civic were 55Watts and seemed like only 1000Lumens or less of light, I stepped up to 100Watt bulbs and got maybe 1.5 times brighter, so maybe around 1500Lumens or less out of the bulbs.
Compared to ~1500Lumens @ 100Watts for a filament bulb as compared to 1700Lumens @ 50Watts, it's a good trade off. The only problem would be stepping up the Voltage since the 1700Lumen LED ran on 18-20Volts. It's not too difficult to do so really though, it's just that at nearly $100 per LED array and fabrication time, the LED alternative is quite pricey.
