Quoted from Mr_Tantrum:
I just wanted to give a shout-out to Comet Pinball https://www.cometpinball.com for their great customer service. I know there are other good LED suppliers, but IMO Comet is the best. Not only do they have great products, but their support is exemplary. Having been in service oriented industries for most of my career, my perspective in business is that things will go wrong. What differentiates the bad from the good and the good from the great, is how they treat their customers and how they address issues when they arise. Comet has always communicated well, takes a customer focused approach to business, and continues to offer great and innovative products.
Comet is and will continue to be my sole source for all things pinball lighting, and I encourage everyone who can use their products to give them a try.
Not to mention that Comet has a wide selection of LED's you won't find anywhere else. I swear by their twin SMDs, and their Matrix light strips are invaluable if you are going for some dynamic lighting.
