George, as mentioned, the thing to look for with LEDs is how many lumens they output. Also bear in mind their colour temperature (daylight is about 5-6000K, whereas tungsten is about 2500-3400K), so a higher Kelvin reading will give a colder light - although this probably doesn't matter so much for a security light, but it might if you want to match it to other garden lights. We have four 15W LED brick lights installed in two raised beds, and controlled from a timer rather than a PIR - as their wattage is relatively low, we can leave them on during the evening, and the garden looks really nice. They are a bit colder than our PIR halogen up/downlighters, but the disparity in colour actually looks OK. It is worth having more lights, but at lower wattage/lumens than the 500W lights you have put out, as very bright lights cast very dark shadows, which can be less secure (and probably annoys the neighbours too....).
