[QUOTE="nickt, post: 686101, member: 4923"] I can't help with the question, but be aware that led Christmas lights can be hard to shoot. Depending on how they convert the 60hz AC to DC (half wave rectifier vs full wave), the lights will flicker briefly at 120 times a second or they could be totally off for half of the AC cycle. With the cheaper half wave lights it is easy to catch a shot with the lights totally dark. That is because 60 times a second, they turn off for 1/120 of a second. Some higher quality light sets might have less flicker. You can usually spot the cheaper ones, if you scan your eyes across them quickly, you can see a very noticeable strobe effect. As a side note, led house lights flicker too, but usually at a higher frequency. They have a more sophisticated power supply but you can still catch them dim or at strange colors. [/QUOTE]
