Get a combination of slip on diffusers for lights you already own and a blf LT1 lantern.
Keep in mind that small lights running on high brightness setting will get super hot.
Head lamps are most efficient as they only put light where you need it, but also most inconvenient/uncomfortable.
For home aesthetic and backup power outage lighting, I really like battery powered fairy light strings, most have simple user interface, OK runtime between battery changes and the distributed nature of the light causes less glare than a single point source.
There are lots of simple light strings using 3mm LEDs that operate off 3 AAA cells. You could power them with 18650 Li-ion batteries instead if you are into simple DIY. A single 18650 cell or several cells in parallel will light the light string for many hours. I know this works because I retrofitted some Christmas decorations that relied on 3AAA cells to operate on a Li-ion battery.
The electricity almost never goes out because we have underground utilities. I have a couple of tent lights and three of those small collapsible lanterns (3 COB strip type) for emergency lights. You would want to put a diffuser inside globe of the collapsible lanterns to reduce the harshness of the light. They are so cheap ($5 on eBay) as to be considered throw away lights. The tent light shown below runs on a single 18650 battery or 3 AAA batteries, has 3 brightness levels, and 60 LEDs for the brightest. I looked at the current price from eBay sellers in China and it costs $5 with shipping. It will light a large tent so would light a small room quite well.
I have quite a few LED lanterns which Iāve bought over the years. Sadly, some of my favorites (Fenix CL20) arenāt made anymore. Iām a fan of the Mr. Beams MB480 lanterns. Runs for 30 hours (high) on 3 D cells. Itās best attribute is the lovely 4000K neutral white light it puts out. It feels far more cozy than the cheap, nasty blue-white lanterns youāll find everywhere else. And when the price is right, theyāre under $20.
I did order the BLF LT1s, but I havenāt received them yetā¦and for the occasional user theyāre overkill.
I am familiar with your problem. There is often a power outage in my area. Our power grids are very vulnerable, primarily due to natural phenomena. Only recently, I found the Presidentās National Infrastructure Advisory Councilās report on āSurviving a Catastrophic Power Outageā (released in December 2018). The information doesnāt provide new explanations but only highlights the problems. I put all the necessary things in a box in case of a power outage. Iām happy with my led lanterns by Vont. These lights hold a reasonable charge and run on batteries. If you put it in the house, it illuminates the whole room. They are safe and solid, a good option.
2000k Fireflies Nov-MU with its diffusion lampshade on is basically a candle. You can even program anduril into candle mode for that subtle candle flicker effect. Very efficient buck driver, especially with the 21x e21a array.
You need 1 lantern for each room of the house, and at least 2 flashlights per room as backups. If you donāt have this many, you are not a flashaholic.
My BLF Q8 makes a fabulous ceiling bouncer at about 1/2 power. The Sofirn SP36 will do nicely, too.
Iāve got an LT1 and usually buy a diffuser if I get a higher power light. Figure it will run longer on lower modes, for longer outages.
Got a Sofirn SP36pro with diffuser and getting an Astrolux MF01 with diffuser soon.
i recommend a nice lantern like the blf lt1 for the living room and a bunch of these flashlights that look like lightbulbs.
i put a bulb shaped light in each room. lt1 where everyone is congregating. lots of regular flashlights to ceiling bounce in coffee mugs.
