    36 Volt - 900 Lumen LED Stadium Lights

    I don't know what happened to my previous message I guess it accidentally got caught in our conversation somewhere! Anyways I'd appreciate it if you could give me some feed back on my idea! So I plan to use a 24v drill battery and wire 7 of these LEDs in series http://m.ebay.com/itm/5-x-LED-3-Watt-Cool-Clear-White-Star-Bright-Wide-Angle-High-Power-LEDs-3w-w-/151187143805?_trkparms=aid%253D222007%2526algo%253DSIC.MBE%2526ao%253D1%2526asc%253D20150519202348%2526meid%253D85ca3f1e7a344f2da881623acc8cb078%2526pid%253D100408%2526rk%253D5%2526rkt%253D25%2526sd%253D151171352633&_trksid=p2056116.c100408.m2460 that would leave each LED with just over 3.4v each which is right in the middle of their reccomended voltage.

I think the battery I'm going to use is an off brand replacement for a dewalt 24v https://www.amazon.com/gp/aw/d/B00760WJ0G/ref=mp_s_a_1_11?ie=UTF8&qid=1477831550&sr=8-11&pi=AC_SX236_SY340_QL65&keywords=24+volt+drill+battery because of the price. I think the resister you reccomended in the instructable still will be the right one (correct me if I'm wrong). Do you mind also providing a new link or explaining how to disassemble the battery in order that it is usuable? The links do not work. Thanks again for everything

    I'd probably use this brand though since it has better reviews https://www.amazon.com/gp/aw/d/B00IOCCDBK/ref=pd_aw_fbt_23_img_2?ie=UTF8&psc=1&refRID=QB817GKA3TYX9K7WQVMT

    Another thing I could do probably is use 1 of these for each LED I have https://www.amazon.com/gp/product/B01COPLDMM/ref=abs_brd_tag_dp?smid=A3MH3MAWW32XOH this is probably cheaper than the drill battery option anyways. What do you think?

    I think I'm going to avoid the quad star because of the high price. As you can probably see, I'm trying to work around a fairly tight budget for each pole. Thanks for the idea though. I've got a plan laid out and it would be great if you gave me your opinion on it. I would use these as my LEDs http://m.ebay.com/itm/5-x-LED-3-Watt-Cool-Clear-White-Star-Bright-Wide-Angle-High-Power-LEDs-3w-w-/151187143805?_trkparms=aid%253D222007%2526algo%253DSIC.MBE%2526ao%253D1%2526asc%253D20150519202348%2526meid%253D85ccf6e45d4e43f3bf736958eef57af6%2526pid%253D100408%2526rk%253D5%2526rkt%253D25%2526sd%253D151171352633&_trksid=p2056116.c100408.m2460 and I'd use 7 of them.

Like I said before, I'd power them with a modified 24 volt drill battery. At this set up would you still go with a 1 ohm 10 watt resister? It's been a while since I've done a project where I've had to calculate the resistance needed, so I'd appreciate it if you could help. Thanks again for everything

    What do you mean by 4 Star LEDs? Thanks

    If I had a pad of paper in front of me, I could do the math, but if I only put 8 Star LEDs on 1pole opposed to 9, would the amperage allow me to get to a smaller and cheaper battery? If so what would you reccomend?

    Maybe these? https://www.amazon.com/gp/aw/d/B00ZWOYV7C/ref=mp_s_a_1_3?ie=UTF8&qid=1477621172&sr=8-3&refinements=p_85%3A2470955011&rps=1&pi=AC_SX236_SY340_QL65&keywords=3w+led+emitter&dpPl=1&dpID=41mYat3sEBL&ref=plSrch

    Thanks for the help and quick reply despite the age of this thread. I'll take a look into those. Oh, I'd like to compliment something in your design that I do not think a lot of people caught. I think it is a great idea on how you put the aluminum angle. I see that this forced all the light from the LEDs down onto the field. This won't be a problem with clamp on lights, but without that design, you would lose light upward. Great job and thanks for all your help.

    Sorry to bother you so much but I appreciate all your time and effort. Similar to in LEDs, there have been huge advancements in batteries too. I have an application similar to yours at a local youth football league that could use something. What kind of battery would you reccomend today, and would it be any cheaper that the $150 drill battery? Thanks again for your time, it will be put to good use!

    but if I wasn't going to go with the clamp on lights, and I would opt to use something like the 3 star LEDs, what would you reccomend there that double be wired to 110v? Thanks

    Thanks for the great DIY. I have been looking for something like this for wiffle balls in the yard. I have a few questions though. 1. What kind of LED's would you reccomend going with now with the advances in LED technology? 2. Do you think I could get these LEDs in 110v so I can use them on house voltage? The reason I would like to do this is so that I can get the light directed down onto the field from higher than just a normal halogen work light stand. Any ball hit high at all gets lost in the sky because there is no light up there. Also, I think I can get a brighter light and a more efficient fixture with LEDs opposed to the halogens. Thanks for your time.
