OK, I remember this one. As I look at the specs it specifies "Non Weatherproof"
The current draw is not bad at 115ma. That could go all night (1.4watt).
Output on it is spec'd at 155 lumen. It is in the "OK" range. It should be able to hit 240 lumen with that current. Did you take pics of how you mounted the tie wraps etc?
Or how you avoid shorting the components on the back side out?
With some hermetically sealing compound applied and a way of stabilizing/attaching the festoon to the LED substraight This is not a bad choice at all. Vibration issues and shorting due to moisture are then alleviated.

For truly supper bright the one I posted earlier is the hands down winner (800 lumen) of all I've seen but it draws a bit more than I'd want, but it's good to go for outdoor use.

The challenge under the hood is getting as bright as you can and not have to worry about the hood being open a long time. The UPCB-xWHP30-FES does that. Its only is lacking moisture resistance and the use of tie wraps for installation integrity.
And yet it may be just fine over time.
Good luck with it.
