Hi guys, Been following this thread for quite a while and it's great. In my own pvc light I built I've been using a 20-watt 17 deg. MR-16 bulb. The 17 deg. spread seems about right for me, but was just wondering if a Solux 3500K 35-watt 17 deg. bulb would be better. I tried a 35-watt 'GE' MR-16 with a 24 deg. spread and it did'nt seem any better than my 20-watt 17 deg. bulb. Just wondering if the Solux would make the difference? 3500K? 4100K? Thanks
