At the rear of my house I've got a 60 ft( 18 metre) garden. Currently I've got a PIR controlled 400/500 W halogen light which lights up most of the garden. It's duel controlled via PIR and an over ride switch. I've now had to replace a lamp, and have now decided that at my age ,climbing ladders to change a lamp is something I should leave to younger folk. So perhaps it's time to look at LED lamps. but looking round, I'm baffled at the array of LEDs available. Current lamp is 8700 lumens, but there also seems the light colour to take int account.

So can anyone suggest the equivalent LED wattage to be comparable to my 500W 8700 lumen light.

Here's a 100W LED flood from CPC offering the same lumen output - https://cpc.farnell.com/v-tac/vt-40101b-5966/floodlight-led-100w-6500k-black/dp/LA07147

 

I’ve got one of these and it lights up our large driveway.

I replace all my halogens round the house with LEDs. Not expensive ones either. I did have one that didn't last very long (few months) but the rest have been fine.

i've noticed that CPC seem to do a lot that fit the price vs power output. Looking into the problem, I'm now wondering if perhaps fitting a 50W unit at house and another in the shed ( bottom of garden ) might be a cheap alternative. Both with PIR.

Aspman- I've done likewise in the kitchn, heaviest light usage in the house.  We had two 4 lamp GU10 X50W ( TOTAL 400W) units , with constant lamp fail. As an experiment, I bought 8 5W poundland GU10 lamps . In over a year none have failed, as opposed to almost constant fail of the 50W big name lamps.  Light output has increased. Kitchen usage now is 40 W with all lamps blazing.

Been completely LED in my house now for over 4 years...large 4 bed detached and all my lighting combined is sub 200w

 

The higher the number the bluer the light becomes, good compromise is around 3500k

We have a total of 63 mr16 and gu10 downlighters in our house that when we moved in were nearly all 50w thanks to the previous owners...   Now they are nearly all led.

 

In terms of your garden, if you can get power to the bottom of the garden ID go for multiple lower wattage pir floodlights to illuminate the various different bits as you use them as opposed to the whole garden as one.

Same. I changed the kitchen over from 6x 60w bulbs (big old orrible brass fitments) to some cheap round flat panet LEDs from amazon. They were about the same size as the old fitments so I didn't need to patch the ceiling but clean white and only about 4W each. they've been great no problems in 3yr.

 

Other bulbs are all LED as well, I normally go for 'warm white'. But I have a few cheaper daylight bulbs as well for utility etc.

Another idea I'm looking at as I've power to the garden shed at the bottom of the garden. ( 2.5mm armour cable to shed). At one time I had an idea of syncing a light on the shed to the one on the rear of the house. But the light on the rear of house is a dual purpose light. it's PIR controlled, with an over ride on the PIR, so that it can be switched on via a switch on the rear wall .
