T5 1.2m LED tube light BW-T5-120-16w
Generally speaking, since T5led tubes are not commonly used, there is relatively little information. The following introduces the specific parameters of Langter T51.2m LED tubes for your reference when choosing LED tubes.
1) Length: 1148±1 mm, half plastic and half aluminum, aluminum base plate for heat dissipation. Aluminum substrate width 9.5mm
2) Power: 16 W or 12w, input voltage: AC 100-240V, 50/60Hz External power supply can be done, AC170-265v, built-in linear constant current power supply, mounted on aluminum substrate
3) Luminous flux: 1600 lm±100 lm At present, there are two kinds of lamp beads, one is 3014 lamp beads with 166 pieces, the other is 2835 lamp beads with 96 pieces, the luminous efficiency of the latter is higher than the former. It can also achieve higher luminous flux.
4) Light-emitting angle: >120° Color rendering index:> 70 Ra or 80, color temperature: 4000k±300k or 6000k-6500k
5) Applicable temperature: -10℃~45℃ 9) Surface temperature: ≤50℃
6) Average service life: 30000 H or 50000 hours
7) Power factor: 110V≥0.98 240V≥0.95 The external power supply power factor is relatively high, the built-in power factor is 0.6-0.7
8) No radiation, no glare, milky white lampshade
9) Shelf life: 3 years, according to customer requirements
10) 1.2m led tube size (mm): Φ16*1148±1mm without needle size, plug common, G5.3
11) Product weight (g): 275±5g Packing size (mm): 1235*210*210 Packing quantity: 50 pieces, packed in pearl cotton, resistant to breakage. Packaging material weight (g): 136g
There are many ways to install the T51.2m LED fluorescent lamp: 1. External power supply, both non-isolated and isolated can be used. If an isolated power supply is used, because the power can be larger, it can be one for two or one for three, that is, a power supply with 2-3 T5led fluorescent tubes. The advantage is that if you install the grille lamp panel, you only need to install one The power supply is enough, and the installation is simple. The disadvantage is that the cost is higher. 2. On the other hand, in order to reduce costs, non-isolated power supplies can also be used. Generally, one for one or one for two can be used. When making T51.2m led tube, the way of stringing the lamp beads will change. When driving with an isolated power supply, generally use low strings such as 10-12 strings. On the contrary, when using non-isolated power supplies, generally use high strings such as 20-24 strings. In terms of cost and light efficiency, non-isolation is more cost-effective than isolation. At present, non-isolation can also pass EMC, which is a development trend.
