Raidlight Ultralight 1200: 128 g, two batteries included and a boost you can forget

Raidlight has been selling trail packs, jackets and poles for years, but never a headlamp before the Ultralight 1200. The brand from Isère is stepping into a category where Petzl, Silva and Black Diamond have long held their ground, with a simple bet: fewer watts than the market leaders, but two batteries and a top strap included in the box, for an official price of 119.90 euros. RunMorph put the brand's first headlamp through its paces, between the strengths confirmed on the trail (battery life, weight, price) and its measured limits (beam quality, a boost mode that only lasts a few seconds).

Raidlight takes on the headlamp market on a tight budget

Raidlight makes trail packs, jackets and poles in Villard-Bonnot, in the Isère region, and has been selling its running range for more than twenty years. Electronics were not part of it until the Ultralight 1200 landed on its official website in late 2023, where the model is still sold today, with a product page republished in November 2025. The brand had never designed an onboard electronic circuit before this headlamp, which explains a clear-cut technical choice: a single LED rather than the two or three light sources found on high-end headlamps, to keep cost and weight down. The bet is therefore less about raw power than about battery life, lightness and above all price: the box includes two batteries and a top strap, accessories that most competitors charge extra for.

RunMorph tip: already running with a Raidlight Ultralight 12L pack or Raidlight Compact Z Carbon poles on your long runs? The Ultralight 1200 rounds out the kit without blowing the budget, as long as you stick to smooth trails at night.

Ultralight 1200 specifications

One discrepancy is worth flagging: an independent test weighed the lamp at 142 grams on the scale in 2023, versus the 128 grams Raidlight now lists on its official product page. The gap most likely comes from a change to the supplied battery between the two retail generations, but no source documents that change precisely, so keep it in mind if exact weight is a deal-breaker for you.

One LED, two batteries included: what that means under the headband

Most high-end headlamps on the market carry two or three separate light sources to even out the beam. Raidlight went the other way: a single SST40 LED, positioned on the right side of the central housing, next to the button. This choice simplifies manufacturing and lightens the lamp, but it produces a round beam with a dense white center and sparser, more orange edges, a deliberate compromise for a first-generation electronic product from a textile brand.

The housing charges through a magnetic port at the back, with no need to remove the battery or protect a classic USB cover. A three-color indicator shows the charge level every time you switch on or change mode: green above 60 %, yellow above 30 %, red above 10 %, with a steady red light below that threshold. The second battery in the box, swapped by unscrewing the housing cap, lets you double your runtime on an ultra without carrying a charger.

The field test: what independent measurements confirm

Le Comparatif du Trail timed Raidlight's claimed battery life instead of copying it: 16.5 hours measured in 100 lumen mode, 8.5 hours in 220 lumen mode, 4.5 hours in 500 lumen mode and about 3.5 hours at the full sustained output of 1000 lumens, figures judged in line with the official claims and with no noticeable drop in output over the hours. The same test, however, points out the limit of the single LED beam: on winding, rough singletrack, you regularly have to turn your head to see properly what is on the sides, an effort that dual-source headlamps like the Petzl Nao RL demand less of.

Outdoor And News confirms the lamp's lightness and stable fit even on long runs, with one specific reservation: the halo of the beam becomes tiring over time. This observation backs up Le Comparatif du Trail's point about uneven light rather than contradicting it. Both tests also agree on the lamp's most concrete weakness: the 1200 lumen boost mode, supposedly the headline figure of the product page, only lasts a few seconds before the lamp heats up and shuts off for safety.

RunMorph tip: stick to the 220 or 500 lumen mode for regular night training, and save the 1000 lumen mode for short technical sections. The 1200 lumen boost is not a reliable option for lighting a technical descent for any length of time.

The 1200 lumen boost mode: the feature that does not deliver

The product name and its marketing sheet put 1200 lumens front and center, the figure that gives the lamp its name. In real use, this boost mode is triggered by a double click and only lasts a few seconds before the circuit heats up and the lamp shuts off for safety, a flaw independently confirmed by Le Comparatif du Trail. The practical consequence for a runner: the figure on the box matches no sustainable use on the trail, and the output you can actually use tops out at 1000 lumens continuous, with 3.5 hours of battery life at that setting. If you compare headlamps on peak lumens without reading the battery life measurements that go with them, you need to know about this gap before you buy.

Raidlight Ultralight 1200 vs the budget competition

On paper, both lamps target the same runner: a budget-minded trail runner who puts battery life ahead of raw power. The Ultralight 1200 wins on three concrete points: far longer measured runtime in eco mode, 11 grams less on your head, and a second battery in the box, whereas the Ontrail 900 makes you pay extra to double its runtime. On an overnight ultra, that equipment gap matters before you even reach the start line.

Strengths and weaknesses

Strengths

• Measured runtime matches the claims: 16.5 hours at 100 lumens, 3.5 hours at 1000 lumens
• Two batteries and a top strap included out of the box
• 128 grams and a stable fit on long runs
• Magnetic charging with no USB flap, plus a three-colour charge indicator
• Very aggressive price, especially on sale

Weaknesses

• Single-LED beam less even than multi-source headlamps
• 1200-lumen boost mode useless in practice, cutting out after a few seconds
• Halo gets tiring over runs lasting several hours
• Undocumented weight gap between the 2023 measurement and the current spec sheet

RunMorph verdict

For a first headlamp, Raidlight delivers a product that fits its positioning: light, long-lasting and sold with everything you need to get through a full night on an ultra. Independent measurements confirm the claimed runtime, which is rarer than it should be in this price bracket. The 1200-lumen figure, on the other hand, is pure marketing: the boost does not hold, and the single-LED beam shows its limits as soon as the trail turns technical. If you mostly run on smooth paths and budget matters, the Ultralight 1200 is an excellent pick. If you string together technical mountain descents at night, a headlamp with several light sources remains the safer bet.

Overall RunMorph score: 7.5/10.

FAQ

How long does the Raidlight Ultralight 1200 last on one battery?
Independent measurements show 16.5 hours at 100 lumens, 8.5 hours at 220 lumens, 4.5 hours at 500 lumens and about 3.5 hours at 1000 lumens. With the second battery included, you double those figures.

Can you actually use the 1200-lumen mode while running?
No. It kicks in with a double click but only lasts a few seconds before the lamp overheats and shuts off for safety. The power you can really use tops out at 1000 lumens.

How much does the lamp really weigh?
Raidlight claims 128 grams with the battery. An independent test measured 142 grams in 2023, and the difference between the two generations has never been documented.

Is the lamp waterproof?
It is IP66 rated, which protects it against dust and powerful water jets. That is plenty for running in the rain.

Is it suited to a mountain ultra-trail?
For runtime, yes. For technical descents at night, its single-LED beam forces you to turn your head to see the sides of the trail: a dual-source headlamp like the Petzl Nao RL is more comfortable on that terrain.
