Portable woods lamp is an advanced clinical diagnostic equipment, mainly used for the diagnosis of skin and hair diseases. Its working principle is mainly based on ultraviolet illumination technology and fluorescence reaction principle. The Woods lamp penetrates the surface layer of the skin through 320~405nm ultraviolet rays, and has an effect on the internal pigments, fungi and bacteria.
There are differences in the ability of different types of skin lesions, fungi, bacteria, and pigment cells to absorb specific wavelengths of light. When the long-wave ultraviolet light emitted by the Woods lamp hits the skin or hair, these substances absorb the light and produce different fluorescent reactions. By observing these fluorescent reactions, doctors can determine whether there are abnormalities in the skin or hair, such as vitiligo, melasma, fungal infections and so on.

The Difference between Portable Woods Lamp and Traditional Woods Lamp
Traditional Woods lamps are usually larger in size and relatively heavier in weight, and are more suitable for use in fixed locations, such as dermatology clinics, laboratories, and so on. Portable Woods lamps are designed to be compact and lightweight, easy to carry, and convenient for users to use in a variety of environments, such as home, outdoor and so on. And the traditional Wood lamps rely on AC power supply, the use of which needs to be connected to the socket. Portable lamps are usually powered by rechargeable batteries and can be used for long periods of time when fully charged. Both the IBOOLO DE-215 and DE-315 have built-in batteries that can be recharged and used repeatedly for up to 6 hours on a full charge.

Application of Portable Woods Lamp
Woods lamp is highly accurate in detecting fungal infections of the skin. Different fungi produce different fluorescent reactions when exposed to the Woods lamp. For example, lichen planus will show yellowish-white fluorescence, while lichen planus will show bright green fluorescence. The Woods lamp is also useful for detecting bacterial skin infections. For example, ringworm will show a coral red fluorescence and acne will show an orange fluorescence. Hypopigmented and depigmented lesions, such as vitiligo, will appear as bright, bluish-white patches under the Woods Lamp, contrasting with the surrounding normal skin.
Woods lamps also have a wide range of applications in the skin care and cosmetic industries. Under ultraviolet light, areas of skin pigmentation become more visible, helping doctors to assess the nature of pigmentation abnormalities and whether they are potentially at risk for skin cancer. In forensic science, the irradiation of the crime scene by Woods lamp can detect potential body fluids, traces and other key evidence, providing strong support for the detection of cases.

Key Factors in Selecting a Portable Woods Lamp
The IBOOLO DE-215 has 5 365nm UV lamps and 15 white lamps, while the DE-315 has 10 365nm and 10 405nm UV lamps. Both portable Woods lamps provide uniform illumination and can be used for accurate diagnosis of fungal skin diseases and pigmented skin diseases, allowing doctors to observe the fluorescent reaction on the surface of the skin in order to determine the development of fungal infections or skin diseases such as vitiligo.The DE-215’s white light mode can be used to observe the morphology of superficial skin lesions. The DE-315 405 nm wavelength is used mostly for use with ALA fluorescence imaging of BCC and AK.

Portable Woods lamp VS. Dermoscopy
Woods lamp is mainly utilized for special ultraviolet wavelengths to detect fungal skin infections as well as pigmented skin diseases such as ringworm in dogs and cats, vitiligo, florid chaff rash, etc. Dermoscopy, on the other hand, utilizes the principle of optical magnification to magnify skin lesions and help doctors observe the fine structure of the skin surface, such as the shape, size, edges and other characteristics of vitiligo. Traditional Woods lamp function and portable Woods lamp function is almost the same, but the volume is huge, and need to connect the power cord to use.
In the outpatient clinic, due to its simple and quick examination and low cost, portable Woods lamp is suitable as a preliminary screening tool for skin diseases, especially for some fungal skin diseases.

Tips for Using Portable Woods Lamp
Before using the IBOOLO Portable Wood Lamp, remove the protective film from the lamp head and wipe the lens. Then choose a relatively dark environment for the examination to ensure that there is no external light interference in order to obtain more accurate UV irradiation results. Place the Woods lamp close to the dermatologic lesion, the distance is usually 5~8cm, and observe the skin condition through the magnifying glass.
Under the Woods lamp, vitiligo generally shows blue-white fluorescence with clear borders; Propionibacterium acnes in acne will show orange-red fluorescence; ringworm can be seen as bright green fluorescence; and yellowish-white fluorescence can be observed in ringworm during the active phase of Malassezia furfur infection.
In daily use, pay attention to the protection of the lens of the Woods lamp to prevent friction and scratching. At the end of each observation or before the observation, clean the lens in time. And regularly check whether the ultraviolet lamp bead of Woods lamp is aging or damaged, if necessary, should be replaced with a new lamp bead in time.

IBOOLO Woods Lamp Detailed Review
IBOOLO has launched two models of Woods lamps, DE-215 and DE-315, which are very popular among customers. The next step is to introduce the difference between the two models, so that you can make a better choice.The battery capacity of DE-215 and DE-315 is 2000mAh, the magnification is 4.5 times, and the window is 50mm.The main difference between these two models is the difference between the lamp beads, which can be said to be the difference between the light modes. The DE-215 sells for $49 and the DE-315 sells for $79.
The white light mode of DE-215 is mainly used for observing the texture of skin surface and lesions, while the 365nm UV mode is mainly used for detecting fungal dermatosis, pigmented dermatosis, bacterial dermatosis and so on. While DE-315 focuses on UV mode and provides two bands of UV light, 365nm and 405nm, so users can choose different bands according to different needs. The 405 nm wavelength is used mostly for use with ALA fluorescence imaging of BCC and AK. The presence of ALA uptake in skin lesions will fluoresce with a reddish hue.
