Guys,

We have another production run on our ditch lights in progress, all but DP 6640 have been out of stock for a while because we sold out the initial production.

We also have LED's available for them, they are a warm white color and come either wired or not.

Thanks,

Anyone have any exact examples of where they got thier LEDs from? Like an exact ebay link on what you used or internet ad link?

Some of these companies that are selling primarily to the model railroad hobby want as much as a dollar each or more for one single sunny or golden white LED. Thats robbery IMO.

I would rather buy some from an electronics supplier and have been doing some studying and investigation on just what type of white looks good for modern diesel locomotives. Seems LED intensity or what ever you want to call it, is measure in a scale of "kelvin" units. A white light measurement. From what I hear, 5000 kelvin units is about right for modern lights. But dont quote me on that. Im still learning here and on a quest to find reasonable priced leds we can use without getting gouged for it.
 


Well, in my other hobby (aquarium fish), we use the kelvin scale when measuring fluorescent lights which also uses the kelvin scale for color temperature.

10,000K is almost blue (corals need the actinic light), where 5,500K is about the color of sunlight and peaks in the red part of the spectrum which is good for plants.

For locomotives, I'd suggest a color temperature of around 3,000K as that is slightly higher than your average light bulb (which around 2,700K)
 
I spoke to the guy on the phone who runs Accurate Lighting about a product question I had a while back. I asked him about what he recommends for modern diesel lighting. I could swear he recommended around 4 to 5000 kelvin for modern diesels. I have been thinking about giving him a call back and getting that information from him again.

Thats for posting that LED link for ebay though. Thats a very good start actually.
 
Guys,

Our specs are 3000 K, low of 2870, high of 3220. These are the SMD 402 which are much smaller than the SMD 602 seen on the auction links.

The product is comparible to the NGINEERING NANO LED, the newer color they have as the older was too blue which is priced siginifantly higher than ours.

I rather stick with 200 for $39 vs 10 for $20. Even though they are a tad bigger they work just as good if not better then the nano 0402 type. I have tried both and the nano ones are great for tight places or N/Z scale models but for anything else I use 0603 or bigger.
 
Ditch Lights

Guys,

Here are samples of our ditch lights, as you can see they are scale. The deck mounted versions (DP 6631/6640) are shown in these images. The cross section of the DP 6631 product is only 1 scale inch. The SMD 402 LED's work best in this application.

Remember that the LED's found on auction sites are just that, the pricing can be a lot higher due to fees, higher bids, and sniping.

We will have a restock for the plastic Pyle Ditch Light used in our DP 6630/6631/6632/6556 in transit by the end of next week.

DP 6640 seen in the last image represents the type of ditch light found on most Canadain units retrofitted during the 1980's. Its cored for the wire to protrude out the back and down into the deck. Compare with the MBE parts.
