How do you install a 50w LED floodlight indoors?

Good idea !
There is no reason that the heat from the driver should add heat to the LED's and the box.

And I think this is how we should get by, at least the ones of us that has a interest in fiddling with our equipment.
Buying cheap products and modding them a bit to make them suite our needs, and make them last longer, run cooler, shine brighter,
and make less noise, hopefully.

This is off course totally unnecessary, but please be careful when fiddling with 120 - 230 volts,
I have no desire to see you electrocuted, from my "inspirational influence" at least not yet.

^^^Duly noted sir. And I couldn't agree more with the modding statement. The cheap stuff begs to be modded .

this has me excited
pull the front glass off for better light, pull the back / waterproofing off for better heat exchange, put the driver outside the growroom like a HPS ballast, sexy.

So what really is the light? is it 1 single 50w LED or a bank of 3w lights or 1w lights or crappy small ones
does it actually work as a floodlight AKA cover a decent distance?

If we're talking about mine I've never actually checked the draw and the company I bought them from was just some crap peddler on Ebay, but they appear to be 2 watt diodes in a 2x10 matrix. Each diode is probably running at 1 to 3/4 watts each at best and possibly closer to a half watt. They're shockingly bright for their supposed draw of 20 watts and it is currently growing 12 Blue Cheese clones in 2 liter containers and doing an OK job of replacing 4 x 23 watt 6500K CFLs, though there's also a larger LED panel in the grow cabinet too. It will soon be joined by another one I'm currently using on a few SLH clones so I'm expecting together they will best the CFLs' growth rate, but we'll see. And there is no way you want to cool 6 or 8 of these. Maybe the ones that cost more run cooler but these are good for me for now.

It would be cool if say 2x20W LED floodlight could replace those 4x23W of CFL's
and there should be savings from avoiding buying new ones vs the led floodlight,
especially when the cooling is seriously improved on the LED's and driver.
If only one 20W LED could replace those 4 CFL bulbs then it's amazing.
I used 4x 20W CFL floodlight to veg for some time, great directional light, and very flexible in positioning.

I've just run the numbers as it would look for me if I replaced 4x23W with 2x20W LED



Edit: To be fair to the CFL's I did run it again with 10 years, and at year 6 the LED lamp is finished
if 30.000h is real and make the green line jump up with +1200 on this chart and then continues as before,
but what is the cost of buying 20W LED in 6 years.

Yeah I don't think 1 20 watt LED is going to replace 4 23 watt CFLs today, but I bet you in 6 years it will . Still I'm surprised how well these Blue Cheese clones are vegging, especially running 12/1. I think when I go to 2 LED lights I'll run 18/6 for a while to see what they can do under that schedule.

Hopefully I can mod the lights sometime this week. I still haven't figured out what to mount the drivers to. Yet .

Just seen this on e-bay. LINK

+ Looks to be a silent passive panel. (IP66)
+ Big panel - good coverage

- heat management could be problematic
- Big panel - overkill for vegging a few plants vs. 10-20W led flood.

I wonder what the actual draw is 28*2W or 28*1.6.

Specs:
Led Module : 80W
Outdoor Lighting Product Type: Grow Light
LED Configuration: 28x3W
6x Blue: 435-445nm
10x Red: 620-630nm
12x Red: 660nm
Floodlight Angle : 75-80 degree
Coverage Area: 2m*1.3m
Floodlight Waterproof : IP66-68
Worldwide Voltage: 85-265V AC
Rated Hours: 50,000







I got some white 10W LED floodlights incoming to replace CFL, I first looked into just buying the 10W LED chips, drivers and heatsinks on e-bay
but the cost was 75% of a finished floodlight, so that was OOTQ. A 10W RGB is also on the way for some spectra testing.

I think within a few years/month LED grow light is something you buy at the local Walmart.

Good find Rasser! The thing i like about the floodlights is that they have a really good reflector inside them. that and my leaves can touch all part of the floodlight without heat stress.
