Yay on the radions!!! I also got lucky and found a super nice guy willing to work with me and sell me his. I have 3 gen 3 Xr30. I LOVE them.... now. Like you, I had trouble setting them up. I even told a tech on about call number three, that something that costs so much money shouldn’t be so difficult to use. [emoji20]. Not his fault. I did apologize, but I was frustrated. Anyhoo, not sure if you have to program yours with a usb cable or not (I did), but I got a reeflink to control the vortech and radions wirelessly and it’s SO bada**!!!! Before because the tank and lights are so high, I had to put my laptop on top of a upside down laundry basket on top of a dinner tray! [emoji23][emoji23][emoji23][emoji23][emoji23]. Quite a mess. I agree with you about the preprogrammed settings being too blue. It was a pain to fix with the usb, but with the reeflink I I can take out the blue and lower the brightness. Mine are only running at 55%. Everything is doing awesome except my cyphastrea and the stylo. [emoji37]. I know cyphastrea don’t like crazy light, so they may be too bright. I’ll probably rent the par meter again so I’ll know. Congrats on the purchase! You will be so happy without the bulb changing, too! Lol Sent from my iPhone using Tapatalk
