lol @ making French fries,,, and burgers too bro! Pricey cos they are Osram dude, the real McCoy smd oslon diodes. From what ive seen them do, pretty amazing & made in uk, boards made by uk M.A.R.L,, big tech company,. but same as you, I aint gonna remortgage to be able to buy one. lol.
The OD version uses the same diodes but less of them per module, hence its cheaper than its GOD brother, but still pricey all the same. Tis a waiting game nowadays for prices to drop or just get a cheaper led that more or less does the same job.
