If that mbrp is first use and you did a good job of cleaning it from the good matches... the mbrp will not be a problem. If the temp of the bulb doesn't raise the contents of the flask too quickly and you haven't gotten the contents too hot, you don't have a problem. If you added some water to start with, and I would have started with almost nine (9) ml of water, you would have been fine if you brought the temp up to about 100C for the first twelve to twenty four hours, then up another 20-40C for the next twelve to twenty four hours.
Everyone has a recommendation, and none of us agree on what it should be. I recommend letting the flask cool, adding 6.3 ml of water, stirring well, adding another gram or so of I2 (since you left yourself with no alternative but to open the reaction up and tinker with something that would be fine if you added enough water at the start and just left it alone) and then using a device called a thermometer to see just how hot you actually get the inside of the flask on that light bulb. If its 105C or higher, fine, let it sit for at least thirty six after it starts bubbling good. If not, find a heat source capable of the heat needed to drive the reaction.
Water is an essential ingredient in this reaction. You either know how to use very clean ingredients carefully with a little bit of water, keeping your eye on the flask damn near all the time until its done, or you don't. Sounds like you don't. I suggest, for those among us with little tolerance for multiple failures on a long learning curve, that you use more water, reflux for longer times, and enjoy success much earlier in your range of experience.
