Im using the following to convert my Clay Paky Mini Scans, this is an area I know very very little around, but Ive had a lot of help over on the Blue Room from someone who has done this before, this may (or may not!) help you For the LED im using https://uk.rs-online.com/web/p/cob-leds/1712923/ and the following holder https://uk.rs-online.com/web/p/led-reflectors/1241018/ (which saves soldering onto the COB) and then reusing an old desktop heatsink and fan https://www.ebay.co.uk/itm/HP-DC7700-SFF-Desktop-Cooling-Heatsink-Fan-435265-001-435063-001/171820492521

Hi, from experience a 300w cool white will replace the 150w Hti. In regard to the other comments, a production led fixture will not replace it on a number of fronts, in my opinion mainly because the chips will not last long enough for their cost of replacement. They will always be more to replace, also they are not as efficient as hti and the half life will always be less than stated in spec sheets usually far less and degradation of the phosphor layer and die is slow and not noticed. However if you design a proper fixture, put in the work it will be way better than both. In this instance also try using a 200w chip first to see if it will do what you need, a 300 will need approx 8"x8" minimum fan cooled heatsink pref 10". In my opinion make your own, it will fit the fixture and cost alot less..
