After repeated discussions with my boss, we have 2 different products can be close to your requirements.
item A:constant current driver IC voltage 90-130V, 9W, CRI70,750LM, this is the most favorable price of US $0.65/pcs.
item B: constant current driver IC voltage of 90-160V, 9W, CRI70,750LM , the price is $0.73/pcs. We recommend item B to our customers, because the voltage can withstand up to 160V, it is very stability and low failure rate, this is welcomed by customers.
We use the constant current driver IC, not RC driver(RC voltage-reducing), if the use of RC driver the costs may be less about $0.05/pcs, but the subsequent use of the process of a large lamp damage probability..
