nerdsforprez Posted September 11, 2015 Please forgive me if this has already been asked before, but i am working on a project that compares PF lights with a third party that I already use (lifelights.com). Now, I know that the third party lights are already brighter, but I am looking @ other characteristics. Real quick, does anyone know (more or less objectively, but per speculation) how many PF lights I can connect to one PF battery box without dimming? I want to connect 4 pairs (8 lights) to one battery box, but want to know if it will dim. I have tried it will nominal dimming....but want to see if I can get others' input, and also see if adding that many lights will too quickly drain the batteries. Thanks!!

MaxSupercars Posted September 12, 2015 (edited) Info text direct from Lego website: "The LED lights consume very little current – you can drive several hundred light units at the same time" Source: http://powerfunctions.lego.com/en-us/ElementSpecs/8870.aspx Lego LED lights consume very little current (about 2mA)... Source: http://www.philohome.com/pf/pflights.htm For comparison here is power consumption of PF motors (no load / stalled): - M motor: 65 mA / 850 mA - L motor: 120 mA / 1300 mA - XL motor: 80 mA / 1800 mA Source: http://www.philohome.com/motors/motorcomp.htm So as you can see power consumtion of Lego LED lights is negligable, can almost be ignored and will not drain your batteries... ;) Max...

nerdsforprez Posted September 12, 2015 Perfect.... thanks Share this post Link to post Share on other sites
Edwin Korstanje Posted September 12, 2015 Best nerdsforprez, MaxSuper had already explane it very good, only problem is how many room you have for all the connectors from the PF lights . Share this post Link to post Share on other sites
nerdsforprez Posted September 12, 2015 I will likely be posting something soon. It is for a completely functional build. If fact, although it will be included in photos, it will be edited out. So I have lots or room for the many connectors b/c I am not constrained by looks or space. Share this post Link to post Share on other sites
