LED Floodlights

Purchased some LED Floodlights for the back of my house and was really disappointed with the light output as it was compared to a 500W halogen Floodlight but it was not anywhere near that! Does anyone have a LED - Halogen ratio chart ?

Ignore the 'Watts' and look at the lumen rating.

You are going to need about 8000 - 10000 lumens to match your old halogen.

Something like this: http://www.ledlightingandlights.com/outdoor-flood-lights-c4/industrial-grade-flood-light-100w-non-dimmable-led-cool-white-9000-lumens-p11?gclid=CNLs1pjPhbwCFSsKwwodmXQA0w

IMHO, standard halogen bulbs and fittings are so cheap that matching their output in LED would take so long to pay off, it's barely worth it.

It would be about 4000 hours before you make any savings.

I replaced 3 x 150W + 1 x 500W halogen floodlights with 5 x 10W LED daylight floodlights. I'm delighted with the result - the colour and coverage is far superior.

I've seen it reported that having security lights that are too bright (as was the case typically with halogen floodlights) is that you are making the difference greater between dark areas outside of the range of the floodlight and the areas that are lit. This means when you're in the lit area, you can't see into the dark areas - perhaps to see somebody hiding in the shadows.

I changed my single 500watt light to two 10watt LED units. The light spread is much better and I'm saving 480watts (6p) for every hour that they are on. Not only that, I don't expect to get up a ladder anymore to change the bulbs.

The neighbours were so impressed they went out and replaced their halogen floodlights with LEDs as well

We just let the GSD out , lights or not , He would find anyone in the shadows !!

I have had a 500W halogen spotlight outside for ten years, replaced the bulb once. Why mess with a perfectly good system?


Unlike some people, who pollute the street with constant flashes that annoy the neighbours, I put in a separate PIR sensor arranged such that passing pedestrians do not trigger it. It only comes on when somebody come towards the house. My front door porch light has a similar set up, so only when I am standing at the door looking for the key hole does it helpfully come on.


This way, the light bulb hardly ever comes on, and lasts forever. The PIR sensor probably uses more electricity than the bulb over the course of a year. The problem is of course, eventually I will run out of incandescent bulbs. Hopefully by then they will have developed better LEDs. OLED maybe?
