Which LED flood light for this purpose?

Below is a picture of a light in the back of a customer's house. It shines down on their backyard. I am not sure of the wattage or anything else since it's up above the lower level roof.

They are happy with the light output, but the cover blew off and the bulbs were a pain to change since it's high up. So they would like me to replace it with an LED that will give the same output.

This is where I need your help, what size light should I get to match the output? I would appreciate any suggestions for the LED light itself, thanks.

You want us to guess what wattage the light is so we can suggest alternatives??????

It could be anything from 100w to 500w in that type of fitting.

A 100w halogen LED equivalent is around 10w

A 500w halogen LED equivalent is around 50w

I'm still not wrapping my head around this. The 30watt 1900 lumen LED's that I have installed seem like they are at least the same output as a 300watt quartz light. Yet the 76watt lights linked to above say they are equivalent to 200watt lights.

Lumen depreciation and dirt depreciation will significantly affect the performance of a fixture over time.

It's tough to compare maintained lumens, LED vs. incandescent or HID, because they haven't figured out a formula for LED. The 76W vs. 200W comparison is probably accurate based on initial lumens.

Sorry if I sound like telsa but I'm IES trained.

That 76W fixture will probably work fine.

I've ordered 7 of these...

I'll let you know how they work. 27 years at 10 hours a day. :eek: Replace a 150 watt Metal Halide :eek:

They steer these LEDs now days...
'The new 18 Watt LPACK is designed with next generation LED chips and phosphor, precision engineered optics and super high efficiency driver.'

$200 in 99's area of the world. :)

I'm thinking it will be fine. You're not going to hang the 11,000 lumen battleship just to match the quartz. You're replacing a cheap piece of crap somebody bought at the hardware store.

At least Cooper gives you a little bit of photometry and your Allpro fixture gives you pretty good spread at 5 foot-candles, which is perfectly acceptable for outdoor lighting.

Just do it.

I know I am late chiming in here-
I replaced 2- 300w halogen flood lights with the FFLED18 5000k Rab fixtures. They are in the front lawn and light up the front of the house. They then had me replace a few wall mounted with the same lights because they liked them so much.

I love RAB's products. They are expensive, but quality always is. 10 year 100000 hr warranty, who can beat that!
