Do you think this flood light is legitimate?
I’m looking to light up an area about 100 meters x 100 meters. It will be attached to the second floor of the house, possibly at the upper part of the gable.
There’s a 100 watt version but I think I’d rather try this one before I spend that much.
Any other recommendations in this output range at this price or better? Must be a reputable seller.
Cool… I hadn’t searched ebay yet since I was waiting for recommendations. I would want to stick to reputable sellers.
This one comes in at $30 less for the 100 watt version and half the price for 50 watt! Also, it’s even local! Looks to be the same light. Only problem is no warm white (If I decide to go with that tint)
Looking forward to more feedback and suggestions!
Thanks Flomotion
EDIT: Here’s the same 100w for $119
Leddna charges shipping on that product I believe. I was looking at the 10w and 20w one but bought it on eBay instead. Can’t remember the shipping cost be it was considerably more.
That is a good buy, and It is a US seller, go buy it!
EDIT: Mod it for 18650s in series, then Review it on BLF!!!
Just a few things to consider. High powered LED’s are great at illumination, as long as you’re standing behind the beam. If you happen to be anywhere in the spot, they can be absolutely blinding and distracting, as well as completely destroying your night vision. Every time you blink, you’ll see blue dots. I have several 10 watt versions coming my way. The idea being: to distribute the light over a wider area to get better coverage without the annoying retina burns. My area is fenced in and only about 50’ x 120’. The lights will be placed around a perimeter for even distribution. Price per watt/lumen isnt that much of a difference if you go with large units or several smaller ones. From what Ive seen in other pics, they look very well heat sinked. If you need to illuminate a longer range, then you’re probably stuck with buying larger floods. IMO, an array of lower powered floods will be far more pleasing to the human eye (especially guests) than 1 or 2 high powered ones.
If I dont like the output, I’ll mod them in strings of 7 with XM-L’s @2.5-3A in series, and power each string with one of these:
http://dx.com/p/24v-3a-iron-case-power-supply-silver-ac-110-220v-124507 I have 3 on the way to play with.
I have a keychain remote that controls 3 separate wall outlets so I can turn them on/off by zone. 21 light fixtures sounds like a lot, but its still just an afternoons work to hang and wire them to AC mains. Tearing them down and modding them for XM-L might be a bit more challenging, but certainly not beyond most of us.
I’ll go with either the 50w or 100w once my dad gives me the green light.
We just talked today about finally rigging some flood lights on the two sides of the house he’s always scanning for critters. Then he’ll use a fixed thrower or a good FTT for checking areas beyond the reach of the flood light.
FlashPilot,
Any time he’d be operating these flood lights all persons (he and my mom) will be in the house so no worries about blinding anyone. The house sits on 40 acres and is surrounded by state and federal land on two sides and very large parcels on the other two. You can’t even see another house from theirs.
Having multiple lower output flood lights would be ideal for dispersed output but he would rather avoid the installation and aesthetics. As long as one powerful light will do the job then he’d be content with that. After all, he’s already happy enough with the flashlight he’s using so a 50w or 100w flood light that he can simply activate with the flip of a switch would be a huge improvement.
It sounds like youve found a great solution. Let us know how it turns out. The eves on my home & work shop are deep and slightly raked, so they will easily conceal the small 10watt versions.
Good luck.

Available in warm also but only 20 watts
Since they all seem to be the same I feel more confident going with an ebay seller. Fortunately, the best deals come from local sellers 
Now I just gotta get the old man to agree so we can move forward on this project. He’s retired but still has plenty on his plate with his antique restoration hobby.
I agree, I think youre probably going to need at least 100-150 watts to sufficiently cover an area that large. Youd probably be better off considering HPS in your situation. It will also be far more reliable and cost effective in the long run. You can often find used complete fixtures on craigslist.
IMHO, if you want new, take your father to the local hardware store and pick out a reliable name brand high pressure sodium or other HID type outdoor lighting fixture. Many are reflectored and can be gable mounted. Any reputable brand will last for years and provide efficient parking-lot style lighting (high lumens/efficiency with great coverage). The ones on the exterior of one of our warehouses have been in service for over 10 years without a single failure. They burn from dusk to dawn every night and keep on going… typical performance.
I want to clarify that I’m not intending to light up every square meter at 90k lux 
I just meant the light would simply reach a 100 x 100 meter area. The DRY would already do that and I expected to improve on that with a 100w LED flood light.
I thought about HID or HPS but we would want instant max output since it’s merely acting as a critter spotting light. That’s the reason I’ve stuck with LED. Would I have an option outside of LED regarding this criteria?
I use a 60W DIY work light conversion and it covers my backyard quite good, 150’ x 150’ ish. Way in the back you can see good enough so you don’t trip on stuff. Within the first 50’ you can see good enough to do work.
I have a similar 10W cool white version bought on Christmas from Wallbuys(under 6:money_mouth_face:. This thing is really build cheap, I opened it up and there was a 3x3W driver in it, earth ground wire not mounted, led with a big drop of grease underneath and hold in place with reflector which was mounted with only 2 screws. But the glass is really thick.
If you put this on a flat area it is bright enough to find your way on a big area, but its not near as bright as a 500W halogen.
'Another resource', that just happens to be your website in your sig. Awesome.
You can post pretty much just about anything you want in the commercial sellers' forum, you know. Nobody is going to fall for the 'hey guys check out this cool new site I found!' spam.
Thre is the 500 watt halgen: $10 10,000 lumens. The 600 watt tota :$140 25,000 lumens. Or a 1000 watt growlight 130,000 lumens. The 40,000 lumen metalhadides for around 100 to $130.
I use as painter lights. Far prefer the 130,000 1000 watt metal halide withewingrelector. I measure about 14,000 lux at 5foot 8 inch from wall. But generally, I can light 1/2 of room at a few thousand lux, 1000 lux is minimal for painting. To get an idea of how bright this is, well, a 500 watt halogen stuggles toget 500 lux at 5’8”, while a cloudy day is 30,000 lux. The real world 500 watt halogen probably struggles to get 200 lux for a few linear foot of wall, when positioned in a practical manner. A shady side of house can range from 700 to 7000 lux, below 700 lux one should wear a headlamp For painting. This is a far greater need for lighting than navigation or grasping for things.
My price point is $100 for 20,000 lumens, for a compete light with lightweight stand that puts light at eye level. I won’t be excited until these get 40,000 lumens for $100.
My eye is on these lights, but too immature yet for primetime.
