I visited the shop personally and purchased floodlight. The person who dealt with me was Tom. He was very help. Unfortunately, you were out of stock so one was posted and arrived promptly. Unfortunately, there were no fitting instructions. I fitted the lamp but struggling with settings for optimal function. I contacted the shop and requested instructions to be e-mailed or posted. I have yet to receive this. Without the optimal setting I am unable to fully evaluate the product. I appreciate if could kindly forward me instructions to optimise setting. Natu Mistry
