Episode 98: Quasar Science Double Rainbow's (RR50 and RR100) 

can't wait for episode 100!!!

Grip Tips is Back!!

Quasar Science??? Sounds scary, like it's from outer space aliens! I'm gonna have to watch this one on mute, with my monitor turned off! Seriously, there look to be a lot of great features on the light - maybe paying for some you'd never use - like all those mounting holes on the back. Until tube lights come up with some real brightness, they're just a novelty, to me. The light fixture looks good, and I like the rubber pieces on the ends. AC/DC is a must, as I'm sure YOU would agree. hehe

He's back! He's Back! Great to see you are posting gear reviews again. Love how in depth you get on these reviews. How do these compare to the new Aputure INFINIBAR?

Thank you for this video!👍🏻 Weird thing is that I got a 4' Double Rainbow unit a while ago but had spotted some serious problems with its abnormally weak blue channel in RGB mode, which caused -- 1) its pure blue looking a lot more violet than any other RGB fixture's pure blue (including Quasar Science's own original rainbow line) 2) its cyan preset looking far more bluish-green than greenish-blue (or something in the middle) since the light's green channel is so much stronger than its blue channel (more than 3 stops brighter), which wasn't a problem with the original Quasar rainbow tube's cyan preset. 3) very noticeably ungradual stepping in its overall brightness (or even flicker-like) when displaying rainbow pixel effect in 48 pixel groups (as opposed to my other pixel tube fixtures' rainbow effect that can transition into/out from blue a lot more smoothly), although the issue is slightly less visible after lowering the number of its pixel groups. 4) just the nearly unusable level of dimness in its blue channel in general, cuz I don't see a point in using this "100w" tube for blue light when it can be almost overpowered by two 5w Aputure MC's or easily overpowered by one 40w Aputure T4c tube's blue light. I first thought that I simply got a faulty unit, but after spotting the exact same problems in the subsequent two replacement units from Quasar Science as well as in the demo unit at my local film gear retailer I've come to believe that it's actually a common problem with this whole product line, despite how perfect every reviewer I've seen on RU-vid claims it to be. So I'm just wondering if you happen to also experience the same issues with your units or if you think I'm just looking at it wrong?🤔🤗

Ay, 3:55 that's powerrCON TRUE1 to you there!

That connector looks like just a locking barrel connector. You don't show the end of the connector and they don't list the type online in product info, but it looks like a barrel connector, some of which just come with a locking screw collar, I've never heard a special name for these other than simply locking barrel.

Happy St Patrick's day!!! I see green! LoL

2:30 Sad Boi! 😢

Good review, unfortunately for QS in Europe, Astera have knocked them out of the ballpark! The only thing I'd say about this fixture over an Astera is that it makes for a better looking practical light in shot. Keep the videos coming mate.💪

4:05 Probably is a 2/3 Pin Lemo connector
