  • Quasar Science LED Tubes

    I think this has been mentioned here before but I just got ahold of Quasar Science's 4 ft Dimmable LED flourescent bulb. It seems pretty simple but this could be my favorite light that I own. For starters its extremely light. You can gaffer tape it to a ceiling or wall. Mount one or two on a stand with a cardellini clamp. I bought a $10 dimmer on Amazon that goes from 0-100. They make 3000k, 5600K, and bi-color switchable.
    They also fit into Kino Flo bases, and common household fluorescent fixtures.
    Right now I have the one 3000K 4' dimmable bulb, but am ordering 1 more 3000K and 2 5600K. CRI is 95+ btw.
    $75 for the light and 2 pin plug adapter.

    Can you do me a favor and meter for ISO 800 24fps from 3' away?

    I'm curious how the direct T8 replacements compare to the crossfade versions.

        No problem. I'm getting F16 at ISO800 24fps 1/48 shutter.

          Yeah I purchased them straight through Quasar. It's a bit of a process. You have to email them with your order request. They email back a quote about 3 days later. Then you approve and they send a credit card payment invoice. Mine shipped the next day but it took about 5 days to get from LA to Chicago.

              That is actually quite impressive.

              Seems pretty much in line with the crossfades. Which means for the price, you could buy four of these things if you're okay with a set color temp. Or buy two 3000K and two 5600K for twice the output and still have almost as much flexibility.

                this might be a silly question, as a replacement in fluorescent fixtures, do i need a override the ballast and just supply straight 120ac

                here's a more straightforward question, if i built a unit to power these lights, what kind of power options do i need to accommodate for.

                  That's what I was thinking too. Getting 4 seems like a better option. Especially since they're so light.

                    To be honest I don't know a lot about voltage, etc, but I know for a fact that you can just put these in normal fluorescent fixtures if they accommodate for T8 size (most do). Here's a video where Hot Rod Camera explains it in depth: https://www.youtube.com/watch?v=Augk09UI0NQ

                      I ordered a handful of these lights last week after seeing them in action on a short film as both practicals and for lighting talent.

                      Which dimmer did you get?

                          Interesting, Im gonna give these a shot as well. Have you noticed any flicker when dimmed down to 40-50%? Any sort of hum?

                            No flicker, but there is a very slight hum. You have to put your ear right next to the light in order to hear it.

                              Lots of DP's using these lights now, I finally requested a quote for 240v tubes. Hope they are priced about the same.
