Does anyone have experience of this lamp? It's LED 12 - 24v and produces an incredibly bright light. What interests me ( and I'm sure other members) is that it is a cold light and ideal for converting innumerable old projectors. It's not the unit I'm interested in but where to get the LED bulb. Any ideas?

I tried to add this as a link! But it's not working for some reason. Can someone tell me why?

So far with led technology Terry, it is not that there is insufficient brightness to use this new method in projectors,it is just that usually because of the shape and size of led lamps, you cannot get the intensity of the light output from the lamps to focus just where you want it like you can with halogen filament lamps with a cold light mirror.

Yes I understand that with the usual LED's that is probably the case, but I think if you got your hands on one of these you would agree that this particular one could be ideal, especially with a suitable mirror/reflector to direct the beam. I know that some high intensity LED's use multiple lights but this is different because it is a concentrated spot of light which is blindingly bright if you look at it directly. it is comparable to the concentrated spot of light given by the filament of say, a Halogen bulb, - but BRIGHTER! and virtually cold! Amazing. It really is worth investigating further.

Wow that sounds amazing Terry, I haven't seen anything like that yet. I do hope you can post the link or type the full URL.
I would be very interested to look into this as an option for my own pj.
Thanks for posting Terry, sounds great! Cannot wait for further details on here. [Smile]

Is it a portable outdoor spot lamp Terry distributed by Lidl?

If it is, it boasts 620lumens output with a colour temperature of 5k and with a 20,000hr life expectancy and consuming just 8.5watts of energy!!!

Yes that's the one. I tried to copy and paste but it didn't work. Don't know why.

If it will fit it might work well with older non halogen projectors that used condenser lenses to focus the light through the gate.

Lets see if this works Terry.

Its just difficult to tell what the actual lamp looks like and what physical size it is unless someone has actually purchased one of these?

I have a plumber doing some work for me and he has one - which is how my interest started. The dimensions of the casting that it is mounted in is 4.5" x 3.5" x 1.5" deep so if the LED unit itself can be removed you can see that it should be small enough for a variety of uses, especially in the conversion/replacement of old incandescent lamps. It would be great if we could find the supplier of the LED that is used in this appliance. Perhaps we could ask Maurice to research it. He is magic at that sort of thing.

As far as I can see, it does not have a bulb but some form of chip, which may or may not be replaceable.
As a unit it's too large for a film projector.

Thanks Maurice
Yes as a unit it is too large but it is only the chip or LED that is what we could use and if that is only the size of the yellow square in the middle of the reflector then it would be perfect. Obviously there must be some sort of driver behind the reflector, but I can't imagine that would be very big. I think I will buy one, dismantle it and find out. I find it quite exciting because the light output is outstanding for a low voltage led. It has to be seen to be believed.

Have a chat with your plumber and see if he has an instruction book or similar which might give some details of the light unit's components.
If the "bulb" was obtainable separately it would need some kind of power supply.

The simple answer is no he hasn't . But the power supply is a rechargeable battery and the supply is stated as 12 -24v on the unit. The battery merely supplies voltage to the 'driver' of the LED, so a 12/24v 1amp DC supply from a relatively small transformer would seem to be all that is needed. Incredible that a 10watt 12v 1amp led can produce such a bright light. It has to be seen to be believed.

I have also seen this http://www.lyco.co.uk/shatter-resistant-50w-led-floodlight-daylight-pir.html which states that it has the output equivalent to a 400w Halogen lamp, there is a warm white one that is slightly cheaper. One for 16mm projectors perhaps.

I also think I saw a rechargeable one as described above in Faversham market Saturday, I can't remember the price.

Even if this particular lamp does not provide us all with a practical solution to extra brightness over our halogen lamps, there is no doubt about it, it won't be far off before we are all switching to 20,000hr led alternatives that offer huge brightness levels whilst offering very little load on our ageing transformers.
Very exciting to see are these advances in LED lighting technology.

Terry it is a really good point this my friend.

These lamps are really handy and I have used them in the good old Eumig for just checking films through. I put the projector close to a 15" screen and you can get enough light out for print checking. At 99p each (pound shops have them) its a low energy low cost way of saving your best lamps. [Wink]

The LED lamps are getting much brighter most theatres I film in are now tooled up with LED stage lighting.

I have a couple of smallish high power cree torches I bought from ebay, proper Am-tech fully packaged ones that have the single cree LED chip. They run on 3 x 1.5 v AAA bateries and last a very long time.

Best thing is the little front unit with the cree chip in comes off seperately and is quite small, and could easily be fitted in to a lamp house, even better it has a zoom function to allow focus of the light so you could move that until the light is just right for the gate, and I suppose put a liitle white dot or two on the side to mark that place, and just run 2 very small thin wires out to the little self contained battery holding unit that comes out of the torch. No messing with transformers or mains etc.

With it zoomed right down you can see hundres of yards, and less zoomed out still a long way and well lit.

These were £5.99 posted and are superb in thier own right.

I`m pretty sure they would work well.

Best Mark.

They are 3 watt but you can get 5w and 12w as well etc. There are lots of chinesey cheap ones as well. I expect the ones with a zoom are the best for the job.

I`ll just check the front lamp unit does screw off this one, but the majority of these cree types they do.

Following on from Mark's post, this looks interesting as an idea.

I was hoping some of our American cousins would jump on this topic and enlighten us as to what this new LED technology offers. What is this little yellow chip that emits such a bright light? I've seen Cree mentioned with some of the products. Is this the name of the chip used? Whadya say USA?

Thanks but it doesn't address the single chip issue but seems to cover multi LED lamps. I'm more interested in the single 'yellow chip' technology which seems to be the way ahead for projector lamp replacement/conversion.

I would like to find one that will fit my editor, I think most editors could use a brighter light.

You are right Mark our sort of hobby or passion I should say is still evolving, blimey I discovered an auxiliary audio output in the back of an Elf yesterday. Still learning!
