I would recommend a SOLA, with red LED. I love it. The model I have 600, is now discontinued, and while affordable options are available, including the bigblue. I've got the bigblue lights too; however, I highly recommend you go with the light in motion SOLA product. It's very reliable and you won't go wrong. There are no hotspots and it's built like a tank. Nothing to open, just plug and play.
If you set your focusing light to red, your camera will focus and the finished image will come out just fine. My SOLA still works and it's been put through lots of tests since 2010 when I first got it.
Hope this helps.
