LED Lighting

Our club is considering replacing the lighting on our trap fields with LED's. Another club in the area replaced their lighting with LED's and the target visibility was so bad that they had to put up some of the old lights to make the target visibility acceptable. It was also tried at our club and the lights were taken down and the old units were reinstalled.

Does any have the specifications for LED lighting that was used and provided ample lighting for a trap field.

Thanks
