I done a quick search on Google, Ebay etc, but did not find a lot of info.

Anyone aware of good reliable LED security lights - the kind with motion detector ?

Alternatively, how about replacement LED bulbs for exisiting lights.

I like my LED flashlights so much I just got to get some LED security lights. My current mains lights use 350W, and I think I could get the same light for 50W of LED technology - just gotta find it !
 
Are you talking about building your own LED security light off of an existing one? Because I doubt any motion sensitive security lights in the general market have high end white LED's. They would most likely be a bundle of 5mm LED's and would not be very bright. If you want, you can take an existing security light and assemble a series of SST-90's in replacing the existing lights. It would probably consume more power than the LED array normally does.
 
Now you're getting all technical on me :huh:

I seen some LED 'bulbs' advertized that you could just screw into existing security lights. About 25W power consumption from what I remember. No indication of brightness. Seen reports they were not durable, and failed after 20hrs (advertized as lasting tend of thousands of hours)

Wondered if there were any better products out there. All these security lights sucking 350W each gets expensive
 
I'm starting to get confused. Your saying that the existing security light is 350W, and the aftermarket ones are 25W, right? This helps save power.

Do you have any links to the ones that you found? Also some links to the security lights you currently have would be very helpful.
 
Don't know the brand of teh one I'm using now - it takes 2 x 175 Watt halogen bulbs (350W total)

I was browsing Google when I found a couple of LED replacement bulbs. They had bad reviews, so I did not bookmark.

Here is a link to one I just found on Amazon (this is a fluerescent type, not LED). It uses 26 Watt and gives the equivalent light output of a 90 Watt bulb. Clearly, I would lose half he light output, but use only 1/7 the power.

I was thinking that the LED versions should give more light output for the same power consumption (as the fluorescent) and would have the additional benefit of quick (instant) start up (kinda essential in a motion activated security light)

Perhaps we need a few more months of development before we get a viable LED security light.
 
I have 4 - 2 x 175 Watt bulbs each. That comes to about 1500W power consumption if they all run together - about 20c per hour to run if you account for taxes and other charges. They come on a lot due to animals passing by in the night. If they run for an average of 2hrs per night, then that equates to $146 per year (2hrs is a conservative estimate)

So based upon this, if I can get bulbs that are just 25W, then I save $125 per year. And if they come on 4hrs per night then I save $250 per year.

The halogen bulbs don't last long and are a pain to change (up ladders). So that would be another advantage of a longer lasting alternative product.
 
No idea on either. Generic security lights and bulbs that you burchase at hardware stores. All I remember is the 350W for two bulbs.
 
Below is a link for the LED security lights I am using. We have 2 of them and are very happy. We started with one in the front....and liked it so much that we bought the second one.

I've actually replied to 1 or 2 other posts from people looking for something similar, you can probably search for those posts too.

FYI - the review on Lowe's website for the light is mine. I am telling you this because it is the only review on it and I don't want you to think it's a second person with the same opinion. We are very happy with it.

That thing looks pretty sinister - 'surrender people of earth' :thumbsup:

If those were 16 3watt R2s you could hurt somebody. Likely 1watters though.
 
Right! The led's are in 3 separate modules, the 2 side modules can be aimed independently. So, they can all face the same direction or you can aim the outer ones more to the side. The light is very white, it doesn't look blue.

I don't know if they are 1 or 3 watt leds......but I'd love to put one under the knife & install some XPG's.:devil:
 
Finally, a somewhat decent LED 120vac outdoor security light.
Specs on it from energy-star website: 34.8 Lm/w, 38.1 watts, 1373 Lumen, and 3500k. Not too efficient but what would you expect for gov't measurement work!!!

16 2-watt LEDs and 6w lost in the transformer/driver????

Its begging for some 'real' LED swapping!!!

Lowes/utilitech claim that it can replace a fixture with 2 90watt bulbs. But, a single 90watt PAR38 outdoor floodlight has 1300 Lumens. So, I see that LED light as equivalent to a 'single' 90watt fixture.

You'll probably need 8 of them to replace what you have. Got $1200 to spare?

Sometimes its easy to retrofit a housing for LED, CCFL, CFL, LVD.... when you know the housing type or the bulb type. I'd rather try to fit 8 LVD bulbs (23 or 40w) into your housing at $50 each, if possible. Does your light use the normal e27/e27 socket? larger e39/e40(streetlight) socket, or is it one of those quartz tubes?
 
I did this several years ago, and it's easy to do. We were having trouble with kids breaking into our garage, and I wired the bulb socket with a simple screw in > standard plug adapter, then to the stereo on the porch. When the motion detector was tripped it turned the stereo on full blast, which was sufficient to wake me up and 'take care' of things.

For flood applications it would be much easier to just use a big Bridgelux or Semi Array.
 
For some reason I did not get email notification on this thread.

Those Lowes lights are $130 each at my local store (40 miles each way). I would need 4 to replace the 4 units I have now. So I'd be out about $500 and get lower performance - payback period of seveeral years.

Perhaps this technology is not quite mature enough yet. If I stick with what I have then perhaps in a couple of years something better will be available
 
Donk,

I have 4 CFL fixtures that I bought from Lowes, at the store, they are not listed online. They have 65 watt CFLs in them (=300w halo's). They are $40 each, that may be a good option for you. I don't like the light they put out, certainly bright enough but too wide spread for me, high color temp, and the CRI is terrible. For now they work for me, but I want to build my own LED lights with lenses to focus the light sort of like 12v halogen MR 16s. Love those, but they eat up too much power, halogens.

Thanks

I was at Lowe's tonight and saw this item. The package said 1900 and some lumens. They also have a different Utilitech that's 2050 lumens IIRC, for about $70... item 205683. So for considerably lower price it's a bit brighter. I'm debating about getting one.
 
Thanks for the update, we'll probably see more of these in the near future

Any indication as to power consumption ?
