So i have a power compact light hood and recently order 2x6700k from AH supply. I read up on an article by Hoppy this the link to the article about lighting that he wrote (PAR vs Distance, T5, T12, PC - New Chart
So as i was reading this article i began to comprehend that reflectors play a big important role and with the new bulbs on the way i decided to improve my reflector. I did some research and found that the best reflective material out there is something called MYLAR. Its much better than aluminum foil. You can find it as tape or sheeting from home depot but is is a little bit more expensive. You can also find it in items such as space blankets or food bags like i did.
Here what i used
Thermal Food Bags $1
Poster Paper $1
Scissors (Who doesn't have scissors?)
All of these items were purchased from dollar tree.
make the proper measurements on the poster paper in order for it be able to fit into your canopy/hood. Make sure to include the "divider" ( which is going to separate your lights. DON'T NOT BEND ALONG THE LINES YET. I made that mistake and regretted it.
After you done making your measurements get your food bag and cut it carefully out. Throw everything out but the mylar sheeting. This is what you will glue on the poster paper.
PUT GLUE ONTO THE SIDE THAT DOESN'T HAVE YOUR MEASUREMENTS. I wanted to do this put completely forgot lol.
Take a credit card and carefully get rid of the air pockets/excessive glue. Then wait for it to dry.
Bend along the lines and put it into your camopy/hood.
One thing i want to mention that there is a big difference in the light. It does go downward towards the aquarium rather than spreading out so i believe this works.
