I use my iPhone as a flashlight all the time when digging around in racks of A/V equipment. I use a blank page in Safari, though. I never downloaded a flashlight app.

I install security panels, card access, fire, and CCTV. I have used my iPhone to light panels while I do the wiring. I don’t have to worry about my phone rolling out and landing on the phone.

I find that going to bed with an iPhone running email (rather than a candlestick, bobble hat and a hot milky drink) means I don’t need to turn on any lights on the stairs, landing and bedroom.

I find myLite great for checking the kids before bed, and I’ve used it to illuminate inside computers too. It is really handy!

One of my major clients is a radiation oncology facility. “The Vault” where people get treated is a sealed room with 8′thick concrete walls. A bit ago, a guy drove into a power pole and took out a whole city block, including our office. Unfortunately, the emergency lights in the vault did not work correctly and a patient, in the middle of her treatment was suddenly plunged into frightening, utter darkness. The technicians hit the button to release the 500lb solid lead door and pushed it open but had no flashlight… my iPhone and FiatLux to the rescue. Woman was relieved and retrieved from the vault.

I tend not to use it much – I have plenty of lighting around here, and I don’t always have my iPod with me – but i’m also in Oklahoma, where the storms come frequently and the power lines are above ground. Last time the power went out, I couldn’t find my flashlight. Rather, my small keychain maglight flashlight had dead batteries, and I couldn’t find the camping lamp that would let me get my work done in the dark. iPod Touch to the rescue! A similar thing happened when I was trying to figure out why my car wouldn’t run right after dark.

I also use it for rewiring my computer setup. I have way too many Macs (and hard drives, and network equipment, and game consoles…) in way too small a space….
