RGB LED Tube Light, 40cm

The 40cm RGB tube light is the tube light in this range with a full published specification sheet, and this page reproduces that sheet for the 40cm model only. The product title also lists 60cm, 80cm and 100cm versions, but their specifications are not published, and nothing on this page copies the 40cm figures across to them. A buyer who needs a longer tube should ask for that length's figures through the inquiry form.

The 40cm tube carries 192 LEDs. Its lamp beads are given as pure white and warm white 3030 beads at 0.5W and RGB 5054 single-core beads at 0.5W. Maximum power is 30W, and the tube can charge and discharge at the same time, which matters on a set: a tube that must stop work to charge will interrupt a shoot, while a tube that runs while charging can stay in place through a long session.

Brightness is stated at two distances, which is the honest way to state it. Illuminance is 1200 lux at 0.5 metres and 350 lux at 1 metre, and luminous flux is 1200 lumens. The drop between the two distances is normal for any light, and quoting both lets a buyer judge what the tube will do at a desk distance and at a room distance, rather than guessing from a single figure.

Colour is where this tube earns its place. Colour temperature runs from 2500K to 8500K, brightness adjusts from 0 to 100 percent, and colour rendering and television lighting consistency are both stated as above 95. The RGB colour range covers the full 0 to 360 degree circle, saturation adjusts from 0 to 100 percent, and the tube offers CCT, HSI and FX modes with 43 scenes. That range makes the tube a colour tool for backgrounds and accents as well as a white work light.

Control comes in three forms: buttons and a knob on the body, a remote, and an app. The remote works on 40 channels across three groups, A, B and C, and carries 16 presets. It uses 2.4G wireless, has an OLED display of 128 by 64, runs on two AAA batteries, and reaches 50 metres indoors without obstacles. The body display is a yellow and blue OLED of 0.96 inches. Groups and presets matter for multi-light setups, where several tubes must change together between scenes.

Charging and run time are stated as 100 minutes to charge and 60 minutes to discharge, on DC 15V at 2A. A buyer planning a shoot should plan around that hour of battery run time, or run the tube on charge for longer sessions. The tube is not presented here as an all-day battery light, and no longer run time is claimed for it.

No minimum order, price, or delivery time is published for this model, and none is stated here. Certificates are available upon request. A buyer who needs a longer tube, a quantity price, or certificates should put the length, the quantity range and the market in an inquiry, so the answer can be tied to the correct model rather than to this 40cm sheet.
