Anbody have the light-up (LED's) TNG Enterprise picture?

I was given one of these light-up (via a few LED's) Enterprise pictures, but it did not come with a power supply. Does anyone have this item and can they tell me the voltage _and_ the amperage the LED's require?

(from ancient experience, I don't want to over-amp any LED's again, as they are ROYAL pain to change due to their size! *grin?*)

If it's battery operated and 12v or less than it should be okay to use the replacement bulbs sold for strings of lights.

It's not battery operated, and it uses (straight) LED's rather than LED bulbs of any sort. And from experience, LED's are very susceptible to over-amperage. If I recall correctly, don't xmas-like LED bulbs encase the actual LED's? (been at least a decade since I saw one here)

I still cannot determine if it's supposed to be 9v or 12v, much less the all important amperage (aka: "mA" on a typical power adapter).

I was hoping someone had one and could take a look at the stats on their power supply leading to the picture.

I don't have the picture of the Enterprise but I have one of a lighthouse that was made about the same time as the Enterprise D pic. The output on the adapter is
12V DC 800mA. It only has 3 LEDs so YMMV.

Thanks! That gives me a rough idea! (the Enterprise-D picture has around 40 LED's). did these come out in the 90's?

What little I know about LEDs is that you generally have to wire a resistor in-line with them to get the right juice going into them. There are a number of LED wiring diagram calculators / generators online, where you enter the voltage requirements of the LED and then it tells you how to wire it and what resistors to use. Then it's just fun with solder and a trip to Radio Shack.

This is a mass produced, sealed product. The only way to access anything that could be soldered, is to destroy the picture (but the scenario picture you paint, is where I learned the hard way, not to over-amp LED's ever again).

Re: Anbody have the light-up (LED's) TNG Enterprise picture?

For anybody else in need of this info in the future (well, it COULD happen!), here it is over 2 years later and I've found out (but not tried yet) that what I need is and adapter with the following specs...
input: 120VAC 60Hz 10w
Output: 12VDC
300mA
Class 2 Transformer
Positive Center {ie. + ---0)--- - }

(The original adapter is a Model: WD1E3006PTP

Note the amperage of 300mA (Gary Mitchell's 800mA adapter mentioned above probably would've smoked these LED's! *ack*)
