TIPS:For save your time and cost,

these leds have been sealing-in the 20mm heat sink pcb,and We also choose to use the better Environmental Protection Material，tin),

Features:

1. Only for Royal Blue (445-455nm)and 660nm red light and Full Spectrum 400-840nm led bulb ,they can be used for Plant Growth Lighting.

2. The 3w bulb can be used as 1W bulb.

3. for brightness，5W>3W>1W4. 5W（4pcs chip,4 in 1）,3W(single chip),1W(single chip)

5.View angle：About 120-140 degree,

6. 20mm heat sink PCB(UP TO 1mm thickness),the leds have been sealing-in.
