Are you looking to replace the Blurple light, and did you buy it somewhere that you can feasibly return it to such as Amazon?
Are you looking for a light that will work well for the whole grow cycle? If you're just gonna use them for the vegetative state the two HLG 65 should provide your plants with sufficient light. If you are planning on flowering with those lights, then you will need significantly more light than they can provide. They are nice little lights though that are made with Samsung LM301B diodes. 30 watts per square foot is a good target to shoot for. Your 2x4 tent should therefore use a light of at least 240 watts.
What is your budget, we can recommend a high quality light for you. Some of these lights use the same diodes as the HLG 65 you are looking at.
