Gear Review – BioLite HeadLamp 330


The BioLite HeadLamp 330 is one of three headlamps that the American company BioLite currently has in its range. It is available in four different colors, ocean teal, ember red, sunrise yellow and midnight gray. The HeadLamp 330 is equipped with a permanently installed 900mAh lithium-ion battery, which can be charged very easily using the micro-USB port. In order to ensure the best possible weight distribution and a good wearing comfort, BioLite has installed the battery on the back of the head.


The BioLite HeadLamp 330 can shine with a maximum luminosity of 330 lumens. The headlamp achieves this when the White Flood mode (100 lumens) and the White Spot mode (230 lumens) are switched on at the same time. The White Flood mode has a wide light cone for close vision with a light range of 16m. The White Spot mode has a combined light cone for long-distance vision with a light range of 75 meters. The HeadLamp 330 also has a red-light mode (Red Flood) and a white light mode (White Strobe). BioLite uses a very breathable material for the headband, which ensures good wearing comfort during every activity.

Water resistance



With a weight of only 69g, the BioLite HeadLamp 330 is a real lightweight among headlamps. In addition, the HeadLamp is classified with the water protection class IPX4, which means that it is protected against splashing water from all sides and can therefore also cope with a small rain shower.

Review – Burn Time

In order to measure the burn time of the BioLite HeadLamp 330, we measured the lux value over a period of time with a micro-controller. We carried out these measurements at -10 °C, 0 °C and at room temperature (approx. 20 °C). The temperatures of -10 °C and 0 °C were generated in a Dometic cool box. Each test was carried out with a fully charged battery and at the brightest light mode. Slight deviations in the measurements are due to the experimental setup, which was not carried out in a laboratory.

The graph above shows that the BioLite HeadLamp 330 clearly loses its luminosity in the first few minutes after being switched on. After that, the headlamp levels off and gradually loses its luminosity over time. After just over three hours, the luminosity of the BioLite HeadLamp 300 drops to 0. There is no discernible difference in the burn time between the tests conducted at -10 °C, 0 °C and room temperature.

Review – Luminosity

In order to be able to compare the luminosity of the individual lighting modes of the BioLite HeadLamp 330, we took pictures in the dark that record the luminosity of the various modes. We attached the camera to a tripod so that we always had the same angle for the pictures. This also enables the luminosity of the BioLite HeadLamp 330 to be compared with other headlamps such as the Petzl Actik or Silva Scout 2XT. On the comparison pictures you can make your own opinion about the luminosity.



The BioLite HeadLampe 330 is a headlamp that is very comfortable to wear. The very small lamp at the front and the battery at the back of the head balance the weight very well, so that you hardly notice the headlamp when you are wearing it. When it comes to luminosity, the BioLite headlamp is at the forefront and the burn time is more than solid.
