    Aircraft Landing light as a singular high beam? 28V??

    Considering doing a high beam intake on the driver side and thought, why not make the remaining single high beam nice and bright which lead me to this

    Its a 450W bulb that needs 28V ... however I am not smart in this arena (any arena?)

    How would one go about powering this? Relay? LMK

    Possibly using a step-up converter like this one? https://daygreen.com/products/12v-to...=9811280363567

    (Disclaimer: I have no idea what I'm talking about.)

    The rated 25-hour lifespan for that bulb is hilarious.

      It won't be very bright run at half voltage, but at least it'll last longer than 25hrs. 10A+ boost converter in a hot engine bay would be ridiculous. The real problem is that's a 7" bulb with a much tighter beam angle than a sealed beam.

        LOL I searched 5.25" and pulled that up...

        How about this one?!? Seems like it will be a tad small but might be a good try, especially for the money

          How long do we really have our high beams on? 25-Hours is 1500 minutes, so that should last pretty long. Especially for >$10/ each

            it's crap for that job. it's a show production light, the beam is not suitable for the road. it's great if you plan on dying in a head on.

            edit: i work in show production.

              The reviews are from people who have used it ... and if it assists in airplanes landing, it cant be that bad right?

              I think the beam might be narrow... so thats the downside I see, but its also really bright. Anyways, this is why I am asking here. I am looking for a single high beam that will be more effective than what I currently have.

              Any input?

                A broadcaster in China mounted a 500,000-lumen flashlight on his car to get revenge on drivers who turned on their high beams.

                    they listed it as a par which is not the quite same as an acl. pars are generally for a wider dispersion wash of light. an acl will have more throw in a narrower beam.

                    edit: were you looking at the par56 or the 36? 36 is probably closer to your needs. also i'd look for one that has a scatter pattern, not just a spot. we run 500w par64s for front stage wash.

                      if you want to run headlight intake, you could switch your lowbeams to a dual filament style, such as the morimoto retrofits people are selling or the holley retrobrights, then technically you wouldn't need either of the factory inner highbeams

                        A lot cheaper than I was expecting.
                        I'd just throw some round auxbeam/similar cheapo LED in there, assuming it's for light output and not looks.

                          This is definitely an option but once wiring is required it becomes a nightmare for me haha...

                          I rarely ever use the High Beam, except to alert 'sleepy' drivers so I am hoping if I'm losing one light to still have a 'nuclear' option to alert them.
