Cheap tat or good value?

What are these likely to be like? Cheap tat or good value?

cheap tat gets my vote

 

[Aesgarth]

Cheap tat seems quite likley, can I ask what you want them for? 10 x 100w LED floodlights is A LOT of light. Each one should be roughly equivalent to a 1000w halogen.

 

[123hotchef]

my ebay LED flood light lasted 6 months I need to lake it down and see whats up

I want four for a barn, the others would likely get used in the other barns at some point. That would be, if they were any good. A forum member has sent me a link to some that he's used with success though. More expensive, but a better buy.

get the cheaper ones! that one looks like the one I have! Mine is out side I think it may have passed water somewhere, but in a barn the cheap ones will be fine I reakon

For using in a barn, and only needing 4, I'd suggest going with the cheaper ones. They should be fine and you'll have spares if they aren't. I work for an LED lighting company but we can't come close to competing with that price.

Depending on the height of your barn I might suggest you go with an LED high bay, rather than a flood light though.

 

[reb78]

Oh, ok. What's the difference?

Can you link to something roughly suitable so I know what I am looking for? I was thinking of angling these downwards, so with their flood spread (120 degrees on the one in the tlc link) hoping they'd fill the barn.

You can get LED bulbs that go inside normal 500w floodlights from Screwfix & Toolstation.

Are those a decent solution.

I bought a pack of 6 50W LED lights from ebay and they have been perfect. The people selling these kind of things will be buying them in thousands so get a great deal.

I've looked at buying 12v vehicle ones to put on my tractor and Landrovers, you can get a pack of 10 for silly money and they sell exactly the same ones in the local tractor place for 4-5 times the price

Shamelessly stolen from somewhere else...

High bays, low bays and floodlights are industry standard terms for the more heavy duty types of light fitting. We will outline the main differences and uses below.

High bays are designed to be used in very high areas (approximately 8m and greater) to provide well distributed and uniform light for open areas. The key element of the fitting which will help guarantee the correct light output is the reflectors and optics used by the fitting. A particular consideration for use with a high bay is if it can light vertical surfaces as well as it can illuminate the floor, or working plane. Lighting of verticals is particularly important when dealing with warehouses where items are required to be picked from a shelf. High Technology lightings preferred high bay solution is the Insignia INV.

Low bays work in much the same way as a high bay, but will be best suited to lower mounting heights. The main differences will be in the lamp types selected and the types of reflectors and optics used. An example of a low bay fitting is the Insignia INM

Flood lights are a very versatile method of illuminating areas where a conventional mounting arrangement may not be an option. The flood light will have an asymmetric throw of light which can be angled into the space to be lit. Care and consideration of glare should be taken when designing with floodlights, due to the brightness of the fitting and the fact it may be angled close to horizontal.

A high bay looks Something like this:

Or

And will usually hang easily from a ceiling beam from a chain - which may be a better mounting solution than the bracket flood light mounting.

A low bay looks like

Which is best will be determined by the height and layout of your barn. If you can give me some dimensions I can see what our software suggests on Monday or Tuesday if that's any use to you...

I'm not recommending any of the products I've linked - I don't know what they're like, just to give you an idea.

Personally I don't rate them, I found that mine ended up with corrosion on the terminals and stopped working anyway.

In theory you can run 10 50W LED unit for the same as one 500W halogen

I have a couple of these up in one of our barns....lights it well enough to go in get whats needed and leave, wouldnt want to work in there, but as cheap lights go...I can see to put the tractor away.

These are for stables, so the other half will be picking feet out etc in there.

I tried an LED bulb in a security light, they do not appear to like working with a PIR sensor in the circuit & cause the led bulb to strobe on & off. Had to revert to the halogen bulb

 

[Aesgarth]

I'd avoid those to be honest, all the voltage control electronics and other stuff has to be built into the bulb, and because it's all in a tiny bulb sized package heat dissipation becomes an issue. LED bulbs are great for replacing household bulbs but as you increase the output heat becomes a big problem. Definitely go with dedicated LED luminaires for something like this.


What kind of lights are in there at the moment?

 

[brightspark]

buy cheap and u get what u pay for. get a reputable make with a 2 year warranty and u cant go far wrong unless u like doing jobs 3 times over

I'd argue that a 100w LED floodlight is more comparable with a 500w halogen, granted this doesn't make the LED sound quite as good but as far as illumination level I feel it's a lot more honest.

I've always had to fit an LED of a higher rating than the conversion tables would tell you to use to get a similar level of illumination.

I've a pair of 400w halogens on a stand that really pumps out the light (and heat) but I haven't found an LED equivalent that I'm happy with, for long time illumination I stick to Metal Halide.

Fair comment, and depending on the fitting the truth is likley to be somewhere between the two. If I have a chance next week I'll do a comparison between a 500w halogen and a 30, 50, 70 100 and 150w LED floods and measure light levels at various distances... That will depend on work being quiet though. I'd be interested to see how the facts stack up against the information I've been given.
