Diah Multi-Purpose Portable LED Light

Editor's Rating
4.8?
Discovered on 2017-11-14

Add light effortlessly to any space with the Diah Multi-Purpose Portable LED Light. This device is, very simply, a flat piece of paper that turns into a radiant light with a single snap. Clasp the two magnetic ends together to turn it on. Featuring a cordless and lightweight design, you can wrap, hook or connect multiple Diahs to create sophisticated lighting structures. Offering omnidirectional illumination, the unique hollow design of Diah allows light to be emitted in all directions. You can also snap multiple Diahs together to create wider bases and possibly use them as pot illuminators or even chandeliers. Additionally, the paper-thin design allows Diah to pack flat when you aren’t using it, making it easy to take with you anywhere. Just slip it in your bag, and you’re good to go. In fact, Diah only weighs 18 grams per light. Furthermore, Diah provides 48-hour battery life and receives power from two replaceable cell batteries.

@Eric Lee:
Thank you for that detailed review! We're Glad you like it and love the martial arts moves :) Yes, we find that these lights are delicate when it's made out of paper. One major learning is to make sure this light evolves into an extremely durable and water resistant version. Don't worry about that slight pop, the area you speak of intentionally has no glue. This gives the led strip slack when it gets curved into a cylinder and ensures the stress isn't taken on any other part of the strip. It seems counter productive but this set up actually ensures the glue doesn't come off else where. Hope this clears it out for you!
Enjoy them and stay bright!

Got the Diah's last week. Have been putting it through the paces. Works very well. We use it as a mobile nite light so that we don't have to turn on the lights when moving about or use a torch light.(It becomes hands free if your wrist is small enough to wrap a Diah around it!) Lights up enough of the area without hurting the eyes. Very cool design. My rather pragmatic wife was impressed by it (not so much the price).
I showed her it can even act as a bracelet by wrapping 2 around her wrists and she started doing kung fu moves!
However 1 perceived drawback: it feels rather fragile and delicate. Not too surprised as it makes carrying 5 Diahs very light, portable and space saving. When I unfold it, the led strip pops up slightly at the edges but it goes back flat when I press it down. Not sure if that will lead to the strip eventually needing to be glued back. So will see how long it will last.
Overall a very good product and glad to have backed it!

@Henry Cheng: Hi Henry! Happy holidays! Yes we haven't sent out surveys for batch 2 as delivery is in February. We will send it out when we have our second shipment ready to avoid frequent request of address changes. Not to worry though your Diahs will reach by the time promised for batch 2. We are just wrapping up Batch 1 deliveries �

Hi SB Design,
I need to change my reward address. how do I change it?

Review from Kickstarter
@Abhishek: thank you! We're pretty psyched too! We will be sending out the surveys soon. We are currently waiting for the final few backers that have errors with payment to rectify them. We are keeping Tuesday as our final date before we send them out. Keep an eye out for the survey! ;)

Hi, Congrats on getting more than 100% Funding for the project. Just wanted to know when the survey would be out.

Review from Kickstarter
Hi Teeny, Thank you for pointing this out.
We closed the batches that had a hiked shipping costs for countries that previously had lower shipping costs and have managed to separate the cost from the rest of the world. In all honesty, this was an oversight in terms of what we thought we were capable of doing on Kickstarter's backend. Upon reviewing on your insistence, it turns out we could actually keep it the same for select countries and have a flat rate for other parts of the world.

Please feel free to update your pledge to adjust the shipping rates as per previous rates.
Thank you so much for pointing this out. Furthermore, we will be sending an update to these backers and inform them of the changes made. Hope this clarifies your concern. Thanks again!

Review from Kickstarter
Yes, but the first batch also shipped to the US. Why the shipping cost differs? Ceteris paribus seller can charge more based of timeframe but it’s unethical to charge different shipping costs to the same country. i.e. batch 1 & 2 to the US should be charged the same shipping cost, which is S$6 originally.
SB Design
Review from Kickstarter
Hi teeny,
We just closed our first batch of Diahs that you had previously ordered from. That batch was limited shipping to specific countries. After a lot of queries of opening worldwide shipping, our second batch is an umbrella cost for all countries.
Look out for a message in your inbox we will get in touch with you and resolve this matter asap. Thanks!

Review from Kickstarter
Initially when I first backed this project, shipping to the US is only $6, why did it change to $10 ?

Review from Kickstarter
Hi Fumio, thank you so much for backing us!
For this version of Diah we’ve designed it in such a way that the switch is the clasp, so you will need to unclasp it for it be off.

Is there a mechanism to turn off the light in the assembled state?
Do I have to bring it back to flat?

@Eric Lee:
Hi Eric!
First off, thank you so much for backing us!
We're sorry it took this long, but we're happy to report that we've opened up shipping for Malayasia for the small batch rewards of 2 & 5 �
Let me know if you need anything else!

Review from Kickstarter
What? No shipping to Malaysia? But, we're like literally right next door. Fortunately I have friends and relatives in S'pore so I will back it. But still, can you consider opening the shipping to your neighbour?

Review from Kickstarter
For anyone following that exchange, I'll add that the ML2032 is likely a better rechargeable option than the LiR2032 from what I can find. The LiR outputs @ 3.6V which can cause problems if the system is designed for 3V. The ML has true 3V output, and the same or slightly better mAh rating, depending on which material datasheet you check. It also discharges while stored more slowly than the LiR, which is something they have a tendency toward, though obviously not as slowly as disposables. For the record, I'm still backing the project, and I think it's an awesome product I'll be glad to have. Heck, I saw ML2032 chargers that plug into USB ports, so I can finally get some use out of my secondary, 6,700mAh, backup power brick.

@StirFry: *wipes beads of sweat off forehead*
StirFry
Review from Kickstarter
And thank you for being so responsive and open. I hadn't realized just how low the average mAh of the LiR was until this comment. I misread your sentence as meaning that the the LiR had roughly 80% the capacity of the CR, when what you said was 20%. That misreading is what caused me to ask about the circuitry. There's optimization, and then there's magic. :p I still think the LiR2032 will work for my use-case because I should get about 8 hours per charge, but I 100% understand your CR2032 design choice now.
SB Design
Review from Kickstarter
@StirFry: thank you so much for asking these questions though, it helps us brush up why we made certain design and engineering decisions. As you may know it's always a give or take with manufacturing haha
SB Design
Review from Kickstarter
@StirFry: Yes your use cases are what we did as well. We went on a month long road trip to the states and used them quite frequently during the evenings.
After a month one died the rest were dim. And the replacing didn't cost much as the batteries are quit inexpensive. You can however replace them with rechargeable lithium coin cell batteries, our battery holder is compatible for both. To answer your next comment, the difference between the battery capacities are so vast that circuits will make a minute difference sadly.
StirFry
Review from Kickstarter
I got a degree in pure math, and am now working on software; I have an embarrassingly poor education when it comes to the hardware side. Is there any possibility that you could optimize whatever circuitry is involved to eke every bit of performance out of the LiR2032 knowing it's quirks compared to the CR2032? Or does that sort of thing not really make a difference? Or even, it does, but not to a degree that is worth the cost of your time, which has its own value.
StirFry
Review from Kickstarter
I can't speak for all of your potential customers. My use would be for these as portable but still nice looking lights that I could stick in a backpack or briefcase. In between uses it wouldn't be a problem to cycle batteries through the charger (which is, I openly admit, another cost to the consumer) if the light had started to dim the last time I used it. Other people may want to use many lights at once, and that would mean either swapping many batteries through one or a couple of chargers (a process that has to be semi-babysat), or buying a full set of spare batteries so that they can do the recharging with less of an immediacy requirement. Both of those solutions cost, either time money, and the one is the other really. Still, compared to a completely disposable battery, I thought it was worth bringing the LiR2032 to to your attention to make sure that yes it was cross compatible.
SB Design
Review from Kickstarter
@StirFry: We have a question for you though... the downfall to Lir2032 is that it's capacity is one fifth lesser than the cr2032 batteries. So you'll end up recharging it more often than using them. Would it still be a trade off that's worth it to you?
SB Design
Review from Kickstarter
@StirFry: thanks for backing us! And thank you for that recommendation, we're doing a quick check online and the costs are comparatively the same. We just need to check in with our manufacturers to see if there's any cost implications, but you're right we too think we need to make that change.
StirFry
Review from Kickstarter
I apologize; Diah was a victim of autocorrect on my phone.

Review from Kickstarter
Have you tested the Dish with LiR2032? They're the rechargeable version of CR2032 and if compatible more people might be interested. 48hrs is not a long time for a light to then have sub-optimal use and eventually need to trash the battery. Could you test LiR2032 while the campaign is ongoing and let us know in an update about compatibility, how long it powered at full brightness, etc?

Review from Kickstarter
@Christopher Mc Verry: Hi Christopher, Thank you so much for backing us! we did explore rechargeable/energy harvesting methods, however these solutions turned out to be too expensive and heavy for a Cordless, lightweight light.

I wish the batteries were rechargable on the unit through usb/solar.
