Research conducted at Cijambe dragon fruit farming field, Subang regency, tested the effectiveness of the use of additional light in increasing the production of red dragon fruit biomass varieties (Hylocereus costaricencis). The sample of the research first measured its productivity in the first and second cycles in order to be compared with productivity after being given treatment in the third cycle. The treatment is light emitting diode (LED) induction of 7 watts, 7 watts red, 6 watts red, and 4 watts red. The parameters observed in the flowering phase were the number of induced buds, mortality rate, flower diameter, and number of harvest cycles, while in the postharvest phase ie fruit weight, fruit diameter, fruit flesh weight percentage, skin hardness, fruit hardness, sweetness degree, organoleptic test , and vitamin C levels. The most effective LED induction in increasing the quantity and quality of plants at the flowering and fertilization phase is a 7 watt red LED. The increase occurred in the average number of buds that increased in the third cycle, while other treatments decreased. The increase also occurred in the parameters of the number of crop cycles to four cycles compared to generally only three crop cycles, average fruit weight of 0.625 kg while generally of 0.4 to 0.6 kg, fruit meat percentage of 81.47% while generally only 78 %, vitamin C levels from normal 8 - 9 mg / 100g to 31,35 mg / 100g, and also increase other parameter that is hardness of skin and organoleptik.
