Indiglo 5 1800 lumen LED light close to Kickstarter funding goal

Australian designed 1800 lumen light claims to be brightest single LED bicycle light

As the days get increasingly shorter, it’s almost time for lights for the morning and evening rides and commutes. Bicycles lights have gotten brighter and smaller over the years, and the Indiglo 5, currently seeking Kickstarter funding, is claimed to be the brightest single LED light with a whopping 1800 lumen output. There are brighter lights of course, but most achieve their output with multiple LEDs.

The Indiglo 5 pumps out a claimed 1800 lumens from a single Cree MT-G2 LED with a broad beam, multiple modes and all wrapped up in a waterproof aluminium casing measuring just 110mm long and 45mm in diameter. It weighs 190g.

The inventors behind the Indiglo 5, Lesley and Simon, industrial designers and cyclists from Australia, have worked on developing a beam pattern that employs all this brightness usefully, casting a wide spread of light across the road rather than all those lumens concentrated in a small hotspot 50m down the road. They also claim a high CRI (colour render index) with a cool white light being emitted which they claim provides better clarity for the human eye.

There are various modes, including a pulse mode that is said to resemble a heartbeat (a steady beam is also simultaneously emitted) and is aimed at ensuring other road uses spot you.

The Indiglo 5 features an internal battery so no leads to worry about. They claim the 5000mAH battery is good for between 45 minutes and 12 hours, depending on the mode. The battery can be removed so you can take spares on a longer ride, handy for an 600km Audax say, and booster batteries can also be plugged into the light for additional burn time.

They’ve developed a range of mounts, from a simple silicon wraparound mount to a dual mount that is compatible with a Garmin Edge computer. The inventors have also planned for the future. If you upgrade to a newer Indiglo light in the future, they’ll recycle your old light or even refresh it with the latest technology in their ‘product stewardship program’.

The Indigolo 5 costs from $95 and there are a range of options available. They are seeking $75,000 funding and have currently reached $69,706 from 343 backers. There are just nine days to go so if you fancy supporting them, now is the time to do so. If they successfully hit tehri funding goal, they aim to start production in December. Check it out at

3 hours max is way too short

IF they can make a "dual mount" like that to fit Exposure lights I'll take it!

Hi Guys, thought I'd pop in and say hi and provide a bit move of an insight. The 5 is the commercialisation of a light that I developed for my own use and is perfect for my needs. The guys I ride with all wanted one and were the first to pledge on KS, so I owe it to them to get this right otherwise my life won’t be worth bugger all.
We are constantly refining the optics and have moved well on from the unit demonstrated in the KS video. Regarding legality, we are based in Australia where there are no regulations, either way, 5 can be run on hi mode (1200 lumen). The boost mode can only be accessed by pressing the power button for 2 seconds whilst the 5 is already on, so it won't happen accidentally. The Hi and boost modes are only for use in dark, unlit areas that are typically free of other traffic such as where I ride (Adelaide Hills). We have on offer an antiglare bezel that cuts off light above the horizon if you feel its needed and depending on how you intend to use it.

Would be interested to see how well that works, if you have pictures. Having tinkered with a similar approach myself it never really produced satisfactory results. Certainly a simple hood is guaranteed not to solve two failings (on the road at least) of torch-style beams: the placement of the hotspot and the wasting of half the output.

There's the Exposure Strada, but the "dip" is just a torch-style beam made elliptical, so it suffers the same failings. I excitedly bought a Luxos as soon as it was announced, purely on the basis of its "floodlight" mode, but that turns out to just add a couple of nearfield LEDs, so - disappointingly - is totally pointless.

I did have a conversation with Kerry from K-Lite about building a custom unit without standlight, which could be wired in alongside a German lamp and be switched on/off from a switch on the bars when moving quickly enough to power it, but I decided the expense of the additional light and the faff of building a tidy switch were both a bit much.

I'm not sure whether StVZO actually prevents building a switchable main beam. If it does then there's no chance of the Germans making one, and since none of the British companies seem to want to produce a proper road beam I can't see them building a road beam and a switchable main any time soon.

Would be awesome, though. The dip is great 99% of the time but there was one winter I was doing a lot of long night rides and by February I was feeling like I had tunnel vision.

Still, this winter I have the Luxos and a Cyo Premium, so I'll at least have a much larger beam to play with. Might even be enough to quell my desire for a main beam completely...

They've worked on the beam? Maybe, but it looks like flat glass,a symmetrical reflector and a forward-firing diode, which still means a symmetrical beam. Which, on the road, means wasted light, less than ideal distribution, and dazzled oncoming drivers.

When is the rest of the world going to realise the the Germans have got road beams nailed, and actually produce a proper reflector?

There's a gap in the market for a German-style beam with additional main beam that can be switched on and off by a remote switch, but unless I've missed something, this just looks like yet another glorified torch.

The light is neither here nor there for me tbh. Lots of bright lights on eBay.

That dual mount is genius though! I was putting my light on the other night and had to slide my Garmin mount along.

Somebody was thinking here!

gthornton101 | 9 years ago

I work in lighting design (although not specifically bike lights) but to echo most other peoples' thoughts - the optics on this look shocking. An up to date, high power, high efficiency LED chip completed ruined by putting an old fashioned torch reflector on it. No good for road use at all.  102

Also, doesn't UK road law limit lights to 1200lumens (regardless of optics)?  39

Accessibility f... | 9 years ago

Yet another light that'll infuriate anyone who's coming the other way and who has to shield their eyes from the stunning glare it creates.

I've said it before, I'll say it again. Buy a light that conforms to German standards, like the Philips Saferide 80. That way, you'll see exactly where you're going, and everyone coming the other way won't be annoyed to feck about it.

Gkam84 | 9 years ago

That type of mounting system is S***, hit some rough roads and your light is coming out, very similar to the exposure of the same size, which jumps out of its mount aswell.

I'd just get a cree light from ebay for super cheap and it will be just as bright. The only issue with most cheap lights, they come with an external battery.

RobD | 9 years ago

As much as I don't like to put something down before given it a chance, I think I'd rather spend a bit more on an exposure or similar that's gone through various versions and developments and a lot of customer feedback. It looks like they've thought out the design well, and the mounts look pretty good, but I'm a little unconvinced

kie7077 | 9 years ago

Only 80-90min @ 1200? they must be doing something wrong, my volt1200 lasts 2 hours on high or 17 hours on low.

Why risk money on a light you may never get when you can just buy one from the shop?

mrmo | 9 years ago

I assume it is a high power torch with no special optics to actually make use of that 1800Lumens?

TheSpaniard | 9 years ago

Just go for one of the Chinese ones on ebay instead, they're about £30 and do the same job.

I did, a couple of times and guess what - they fell apart pretty quickly.
