Over the past couple years I tested numerous white LEDs for lighting holograms, and I would like to sell the ones which were not used (these were never connected or powered up, except for the 2 noted below). These are all good for lighting holograms at close range (except the blue ones). In my opinion, the best are the 8mm LEDs (first on the list) that I bought within the last couple months. The voltage and current requirements are noted on each package. I've included the eBay item number for most of these where available, but the numbers may be outdated. The price is $60 for the lot, shipping included inside the US, or $75 total with overseas shipping. Payment by PayPal.
