*The Relax scene is 56% brightness. Lumens calculated by multiplying brightness at 2000K (342 lm) by 0.56.

And then for the gen 3 A19 white only bulb:

SceneColor temp (K)Brightness (lumens)
Bright2700840
Dimmed2700~252**

**Dimmed is 30% brightness. Lumens calculated by this formula: 840 x 0.30

How bright are Philips Hue light bulbs?

Philips Hue offers different ranges of brightness in its smart bulbs so that you can get the perfect amount of light for any room in your home. Use this guide to learn more about lumens and smart bulbs, how to convert from lumens to watts, and how to choose the right brightness.

What are lumens?

Lumens measure how much light the human eye can see coming from light source — the brightness of a light bulb, for example. The higher the lumen rating, the brighter the light appears. This measurement is different from watts, which indicate the input power of a light bulb rather than its light output.

Model 1600 : Up to 1521 lumens

The brightest smart bulb from Philips Hue, this range comes in WhiteWhite ambiance, and White and color ambiance. Light up larger areas of your home, such as the garage or kitchen, with bright light for functional tasks, or dim down to set the mood. This range comes in standard A60/A19 bulbs with E26/E27 bases.

Looking for 100 W? If you want a bulb that’s as bright as a 100 W incandescent bulb, this is your pick.

Model 1100 : Up to 1055 lumens

This range offers powerful light in WhiteWhite ambiance, or White and color ambiance that fully illuminates medium-sized spaces, such as hallways — yet can still be dimmed to a low glow. You’ll find this range in standard A60/A19 bulbs with E26/E27 bases. 

Looking for 75 W? When converting lumens to watts, this bulb is the equivalent to a 75 W bulb.

Model 800 : Up to 806 lumens

The most common Philips Hue brightness, the 800 range of Philips Hue bulbs are available in WhiteWhite ambiance, and White and color ambiance. You’ll see this in the standard shape (A60/A19) and base (E26/E27). 

Looking for 60 W? This bulb is equal to how many lumens are in an incandescent 60-watt bulb.

Video Recording

I am looking for a simple audio / video recording solution that can help me to record computer screens with audio.

I am planning to use OBD software. It’s free and open source. Here is a good tutorial on this tool.

download from here; It’s free.

https://obsproject.com

Set base resolution = 30fps, video will be crisp. I am leaving it to default.

OBS file extension is mkv. We need to remux to get MP4. The reason mkv is default, a lecture of 2 hours terminates after 1 hour then we would have the video up-to the point of failure. If we set default to MP4 then risk of loosing 2 hour lecture is very high. Leaving it to default. You will be Happy doing remux as a second step.

OBS start and stop buttons are visible. We can edit it in editing software or we can use shortcuts to start and stop the video. We can add Hot keys if we want. The path is Settings -> Hot Keys. Add your favorite keys here; Press

ALT + F2 = Start/Stop

ALT + F3 = Pause/Resume

#-1. To resize video of me, click on Video Capture device, press ALT key and resize. This will crop the image.

#-2. To record a specific area of screen, Click on Display Capture, Press ALT and zoom in to screen area. This will record that screen area.

#-3.   I can add a logo by dragging and dropping inside recording screen. I can make it smaller or larger.

#-4. To add a border around my face, add color source that match up with my logo. Add a color source.

#-5. To hide source from video, simply click (toggle) on the eye and my video or color source will go away.

#-6. To lock items, simply click on lock and now all of my sources are locked.

#-7. To have a cleaner interface, click on video, logo and color and make a group. Press shift, select sources and select “Group selected items”. Name them “Logo and Video”. This helps organizing my resources a little bit better.

#-8. This is trick. I am explaining and doesn’t want my face to show up. Click on Scene on the top. This will just show the desktop. When I am done with full desktop and wanted to bring back my face on the desktop, I can click on my focused scene “Proxmox performance – IPERF3”.

#-9. When I switch screen from scene to scene, it makes a hard cut. What if I want to add a transition? Click on Scene transitions and pick “Swipe”.

#-10. I don’t want OBS to shift my scene. Create following hot keys. Alt + F5.

#-11. I can add audio filters for example “Noise suppression”. This can help to suppress the noise of dog or lawn mower outside.

#-12. I can transform my resource. Click on the group and you can see transformation there.

#-13. We can re-arrange UI. To reset UI, click on View and Reset UI.

#-14. We can create profiles. Profile will store video specific scenes, for example “YouTube profile” etc.

#-15. Studio mode help us to preview without recording. The left side is live recording and right side is preview. We can make changes to the right side and when done click to swipe it to live view.

Now comes Video editing part;

There is another open source audio / video editing software, DaVinci Resolve. Here is the URL

https://www.blackmagicdesign.com/products/davinciresolve

This can be installed using admin account but wouldn’t be visible to user’s other than Admin. To make it visible to say Shahzad user account, copy admin profile to a user-defined folder e.g c:\video\blackmagic folder. Open folder and run it from there. took me some time to figure out this work around.

The best thing is to use your iPhone for voice recording. Laptop voice sucks. In my simple case, I don’t need to buy any voice recorder.
