Field Lighting. Advice needed

[tillytime]

I'm looking to buy a light to illuminate my field. But there is sooooo much option. Biggest question is what bulb?
Criteria:
Needs to light up to 10 meters (ish)
Be manual controlled (Not PIR sensor)
Run off of battery (car) or solar
Around £40 - either one full price or two cheaper


I have tried a 80 LED solar PIR light (which was rubbish) - the sensor didn't span far enough, and the light wasn't very bright. I did adjust all of the settings!


Please help ..... what should I consider

Thank you.
Triple chocolate cookie for anyone who actually knows what I'm asking!!!!

We use the normal security lights which you have on your garage etc. Not sure exactly what kind they are. They are on a sensor but we have put them at the top of a long pole right at the gate and they go on when the horses come to the gate and wait to be brought in.
