We normally use Principal LED's QWIK MOD 3 bulbs to light up our 6 inch sign cabinets, but to try and save money we decided to give them a try. Of course we will not put them in any closets. shows that the Principal's LEDs are noticeably brighter, but the viewing angle is where they really outshine this product. Other reviews list the blue cast you can see in the picture. The cost of the main LEDs is a little over double the cost of these modules, but I think we'll use fewer main LEDs to get the same result. Notes: Both LED strips - 20 Rextin and 25 Principal - were connected to the same 60W LED driver.
