DIY fluorescent LED bulbs provide customizable lighting alternatives for photos, video


    Along with clamp lights, another option for continuous lighting are LED fluorescent tubes.

    Adam from Droi Media did a couple video tutorials in 2019 showing how to make your own light tubes, as well as a mount and dimmer for them. He estimates the costs for the lights at less than $25 a foot.

    Many of you are probably thinking that sounds pretty stiff since you can get a 4-foot LED fluorescent tube for about $63 at a warehouse hardware store. And you'd be right, except for two things: 1. That's just the tube and not the mount or the way to power the light; and 2. You have to buy a 4-foot light.

    Adam's plan allows you to customize the size of the light to fit your cases, and they don't require all the other major hardware you need to power them.

    Basically his design involves wrapping LED strip lights around a wooden dowel, attaching wires for the power supply and inserting it in a frosted tube secured by screws through the end caps and hooked up to a power supply. The hardest skill in the whole thing appears to be soldering wire.

    He also shows how to combine them on a mount with a dimmer switch. It's a great addition for your video or studio photography kit, and being LED, which can also run off batteries, used in the field as well.

Night-photography lighting in your pocket

    The folks over at Digital Photography School had suggestions on how to use your cellphone for dramatic night photos.

    In the article, it suggested using the LED lamp on your smart phone as a key light for portraits. It throws adequate light on the subject, while at the same time preserving the ambient light. It works better than flash which tends to create a harshly lit image of the subject against a nearly pitch-black background.

    This is not the first time someone has suggested this. Jared Polin over at FroKnowsPhoto.com has also advocated this technique for years. The best example is his photo of a meetup in front of the Kolner Dom in Cologne, Germany.

    But the DPS article acknowledges that there is a problem with this technique. The LED on the phone is not the brightest light, as it's a single bulb. That means you have to hold the phone pretty close to the subject and possibly boost your ISO to boot.

    But there's a way to shed more light on the subject without breaking the bank. Harbor Freight has 144-lumen led flashlights for less than $4 that can put out more light than a phone. I keep a few of them around my house (I usually pick them up when I get the coupon to get one free) for emergencies, but I think I might add it to my photo bag as well.
