Aputure B7c Bulb – First Look

Aputure B7c Bulb - First Look

Handling existing lighting features in a location aka “practicals” just became easier with Aputure’s launch of the new B7c bulb (formerly called the “RC”) designed to turn consumer lamps into light sources suitable for professional TV and Film. I took the Aputure B7c bulb into the field for several projects and the full writeup is below.

One of the first things the gaffer team and I do when we arrive at a “real” (as opposed to studio) location is we change out any existing bulbs. Over time home owners and renters change out dying or dead bulbs and they morph into a mishmash of different brands and different color temperatures and the results are pretty ugly on-camera. In the past we would simply have a few high CRI consumer bulbs and swap them to allow for dimming and, at the very least, a consistent look to all the practical lamps in a scene.

Where things start to become tricky is with dimming or color control from bulb to bulb or with a “gag”. For our purposes I’m defining a “gag” as a flickering light in a horror film or a short circuiting source on a spaceship etc. Every gaffer has their own tricks for accomplishing the above and occasionally a gag might require hiding in an uncomfortable spot just out of the shot — not ideal.

The $70.00 B7c bulb from Aputure solves several problems related to the use of practicals and it can be introduced seamlessly into your on-set lighting workflow. Arrive at a location and swap out all practical bulbs with the B7c and you’re already headed toward a better looking scene with a variety of easily controllable and unified (in terms of color) bulbs.

Check out the above shot for a digital branded piece I DP’d for Nerdist.com/2K Games. This was my first time working with two B7c’s and the results look good. The full video shot on Canon C300 MK II/C500MK II and Sigma Cine Primes is below:

In fact, the B7c fits a great niche inAputure’s product lineup and the industry as a whole. For Aputure, this is a small feature packed light that isn’t a square (a la the MC or AL-MX fixture) and one that can be used in tons of scenes where the MC works as an on-cam practical in places like a warehouse set or an airport or in a sci-fi film, but that’s where its usefulness ends in terms of placing it in a “realistic” scene. An MC fixture doesn’t work in a film set in the 1940’s, but the B7c would, for example.

For the industry as a whole you’ll be hard pressed to find a competitor in the filmmaker focused LED bulb category beyond Astera’s new $105.00 NYX bulb. Aputure clearly knows this and they went ahead and put together a head to head chart of the feature breakdown between the Nyx bulb from Astera and their new B7c. Here’s the chart:

The above chart lays out everything in a straightforward way, but the clear differences between the B7c and the Nyx revolves around the internal battery present in the B7c and the Nyx has a slight output and larger kelvin range advantage. Beyond that, the B7c has a slightly wider beam angle and on-board intensity and CCT control for about $35.00 less.

I find the internal battery does last a little over an hour and it provides for additional creative mounting options. The B7c does tend to get a little hot when placed in a standard E26 or E27 lamp socket and operating at 100% for some time, but it’s nothing like the hand melting Tungsten hot lights of old. Aputure does note that the heat build-up can extend charging times.

In terms of output you’re still working with a 50W Incandescent bulb equivalent here, so for 360 degree steadicam or gimbal shots you will likely need to hide some lighting in the ceiling or outside windows depending on your exposure, but you could certainly key an actor with the B7c if the lamp is placed close enough to your subject. It’s also important to keep in mind the type of lamp shade you’re using in these scenes and you’ll want to work closely with the art department to nail the look/output of a given lamp shade. Testing this before you arrive on location, as always, is important.

Lots of control options available on the Sidus Link app. Image Credit: Graham Sheldon

I’ll leave you to decide which bulb is better on paper, but if have already invested heavily into the Aputure ecosystem with Sidus Link bluetooth connected fixtures then it’ll be a hard sell to decide to gravitate to the Nyx bulb at this time. The same is true for Astera — if you already have a bunch of their popular Titan fixtures then the Nyx bulb might make more sense to keep things streamlined while on-location.

Having used both the Sidus Link and the Astra app I’ll say that I personally find the Sidus link app to be a little more intuitive to use out of the gate. Astera also has you purchase a separate $400.00 CRMX transmitter to connect to many of their lights, but the Nyx bulbs do only need bluetooth control — something to keep in mind with that ecosystem.

Currently charging is limited to using an available household lamp and charging to 100% takes about 2-hours per bulb. This isn’t an ideal charging solution for every production of course (carrying a house lamp for charging in a G&E van is weird or should they be in the art van?), but Aputure promises an 8-light charging case (pictured above) is coming next year priced at $699.00 in the US. Budget allowing — the upcoming charging case looks like the way to go in my opinion for ease of use from location to location in professional production.

Conclusion:

For the type of work I do the B7c is an easy purchase for me and I plan on being one of the early folks on the pre-order list. Given that this is such a new product category the comparison shopping takes about five minutes and for me, the B7c bulb fits in very well with my existing Aputure fixtures.

**I’ve reached out to Astera and I’ll update here if I’m able to do a head to head comparison with a Nyx bulb.

The 160 degree angle does not work for most lampshades (look at the “Internal batteries!” Image at the top of the article) and the size seems to make them useless in most northern European designer lamps. Cheap oldschool tungsten incandescent bulbs are still the best solution for me, different color temperature is rarely a problem (of course same type incandescent bulbs which have burned at about the
same time), as opposed to LEDs and fluorescent lamps which have given me a lot of problems.

Hi Mike,

Regarding the “internal batteries” image this household lamp in that image has the bulb sitting too high. For optimal light coverage in the whole shade I would go with a bigger shade and a lamp that has the bulb socket sitting lower in general. Definitely worth testing in advance.

That’s an Aputure MC in a lightshade in the background. Looks fine to me…

I agree; I’m pointing out that a light with a smaller angle is fine. Also think it’s hilarious anyone thinks these are expensive for lighting kit!

Overpriced when you can get tungsten LED equivalent for under $5.00.

Hi Steve, I’ve had all sorts of quality control in terms of matching color and flicker issues at different camera frame rates with LED equivalents in that price range. I’m happy to spend a little more for the peace of mind personally.

How about the size at the middle and top? Does the BC7 fit into household lamps. I know the base is the correct size, but after that it is a whole lot wider. I certainly have a few fixtures in my apartment in which that build would simply not fit at all.

Hi Jamie, I tried the lamp in five or six different fixtures and had no issues. Absolutely lots of variety here in terms of household lamps, so worth testing before arriving on location.

I agree. It’s a luxury item.

Hey Steve. Good luck with your sub $5 bulb and consistent temps between bulbs, no flicker, color/effects options, ability to match other lighting, and the use of a practical without power. You just have yourself a great time.

What about the Philips hue?
+Small size
+Much lower cost 25$
+mesh

– short range but meahable
– hub with Ethernet only

? Flicker free?
? Stability?

Hi Jonas, Aputure actually made a comparison chart with the Philips hue as well, but I didn’t include here because I don’t see them as a direct competitor personally. I own a few Philips hue bulbs and you’re exactly right about the connectivity being an issue and I’ve seen flicker at different frame rates with those, but didn’t do an exhaustive test since they’re more consumer focused anyway. The aim for Philips isn’t crazy high CRI either, so that’s something to keep in mind.
