Discussion Overview

The discussion revolves around the feasibility of using 120V floodlights powered by car batteries in a remote area. Participants explore the compatibility of halogen worklights with DC power and the potential need for additional equipment like inverters or generators.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about connecting car batteries in series to power 120V halogen worklights, noting the short duration of use.
  • Another participant expresses uncertainty about the effects of applying DC power to AC lamps and suggests using an inverter or generator for 120VAC output.
  • A participant mentions having a 400-watt inverter and questions whether new bulbs would fit in existing light housings, indicating a desire to utilize available resources.
  • Another participant recalls having automotive lights available, suggesting a possible alternative to the original plan.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to power the lights, with multiple competing views on the use of inverters and the compatibility of different types of bulbs.

Contextual Notes

There are unresolved questions regarding the electrical compatibility of DC and AC systems, as well as the specific requirements for the halogen worklights and inverters mentioned.

Who May Find This Useful

This discussion may be useful for individuals interested in DIY projects involving portable lighting solutions, particularly in remote settings, and those exploring the use of automotive components for alternative power sources.

I am trying to do a project in a remote area but I need bright lights. I already have 4 car batteries and 2 tripod halogen worklights from home depot (http://www.homedepot.com/h_d1/N-5yc1v/R-202066789/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053"). Each light is 500 watts so at 120 volts which would be 4.12 amps. Could I hook up these batteries in series to AC lights? I only need light for about 10 mins so I don't need that much juice. Any advice would great, thanks.

I don't know what will happen if you apply DC to those lamps.
They do sell Halogen lamps with 12VDC ratings (automotive purposes). If you want to run 120V lamps, I would suggest an inverter, or a generator with a 120VAC output.
 
I do have an inverter however its only rated to 400watts. Would these bulbs that you sell fit in these lights or is it all new housing. I wouldn't mind buying new bulbs, I was just trying to be resourceful and use what I have.
 
i didnt even think of auto lights, slipped right passed me. I do have a bunch of hellas floating around the garage.
