Im long overdue for a light change and have been doing some bulb shopping. I am a huge ATI fan and my past three bulb configurations have all been ATI. Before that was Geismann and before that was mix of Reeftec/Sylvania.
With the current price of ATI, actually most "hi end" lights, i find it very hard justify paying that for bulbs. Most shops have dropped the cheaper brands and force LEDs on every customer. So i began looking at cheaper bulbs because i'm still not sure if i'm ready for LED. I pulled out an old sylvania bulb to check colour spectrum before ordering anything. When i placed it next to one of my old ATI's something struck me. Id heard a rumour that most bulbs are made in the same factory ad that the PAR of the blue sylvania is almost exactly the same as that of ATI Blue Plus..
That's when i discovered the Sylvania Marine Star. Ive never herd of it nor seen it in any marine shops, possibly becasue3 its a cheapo bulb and i have an almost unnatural love for ATI. This light sounded uncannily similar to my favourite ATI bulb, the 15000k Coral Plus.
Here is the spectum of the ATI Coral Plus:
And Sylvania Marine Star:
Yes, they do look a bit similar. ATI graph has been smoothed and its y-axis is much higher, but then the peak on the sylvania graph clearly extends above the upper limit of its axis. How about i merge them:
Are those two lights any different? Are the slight differences artifacts from the merging process? Are the apparent minor differences even significant?
