I got a led light given to me that is a 24v light and im looking to wiring up a step up box and slapping it on the front of the quad. The light is retail 495 bux Cat happy so id love to make this work.

Here is the specs, what size of step up should i use?....cant find the watt specs tho.

Its a speaker flood led light 7150 model

for step up i was looking at this think this will work???

Thanks alot guys Rockerdude

This should work well! Step up unit meets all your criteria and more! I would put in-line fuse on 12volt input of 6amp rating! Of course all connections should be soldered and heat shrunk! Thats an insane amount of lumens!!

Thanks glen ill make sure i solder and heat shrink it all and a fuse inline of course.

It should be pretty bright ill try and get some pics

 

[glenvolb]

Make sure light is turned off otherwize you will nuke the camera lens lol!

lol ok

thats an 80's song, I think

Your specifications showing it draws 3 amps @ 24VDC is 72 watts only. I imagine that 10 amp or 240 watts or at least a 6 amp minimum DC to DC converter is a good idea to handle possible peak inrush currents. It should work I'm thinking. For comparison in the amount of light, your standard 110 volt AC house hold flood light is about 1500 lumen or VEL=1500

lol holy crap im going to blind everything lol....wyo do you know what kind of draw on the charging system it will create?....hoping not a lot

 

[glenvolb]

Your led is rated at 24v 3amps . volts times amps equals watts or 72watts. Input voltage is 12volts therefore current will be 6amps equalling 72watts! I suggested starting with in line fuse rating of 6 amps but you may have to bump it up to safely as high as 10 amps to satisfy in rush current, line losses,and internal losses in step up transformer! I recommend # 14 wire min ,better yet #12stranded wire to limit these losses! To answer your ? 6amps draw is roughly what you are adding to charging system!

Glenvolb gave you the correct answer, approximately 6 amps not considering losses in the DC to DC converter which may be no more than a 1/2 amp or less.

This link below you can refer to for wire properties showing the wire gauge required to handle a known amperage. A good link to bookmark. The voltage drop calculator is pretty handy also. Using that data shown there under the power transmission column, you should at a minimum probably use 12 ga wire for the 12v side and you could get by with 14 ga wire for the 24v side and not experience too much voltage drop and handle the current. Either 14 or 12 ga wire on both the 12 and 24volt circuits will work too. My self I'd use 12 ga just because it's stronger and would be less prone to break with vibration.

Um see specs, 85% efficiency so I would plan on at least of few % less for efficiency when you add in conductors and connectors not to mention efficiency is bound to drop as the converter ages.

Thanks guys i got it all wired up how you suggested....here a little pic its the one in the center. Im not sure why its yellowish tho?...maybe its not getting enough power?
