Hi All, This is a UVB COMPACT question, I know there will be many different ideas about distances and outputs etc, some use tubes, others compact and there are the MVB crews... But my main question is, if a bulb is titled a reptile UVB bulb (output of 10.0) can you trust that it is, and that changing said bulb EVERY 6 months keeps you in a safe zone for use regardless of brand? Are there bulbs that are marketed falsely and even positioned in a low line enclosure will give off no benefit and risk MDB etc.? For example, please see three different types below, should these (within reason and enclosure position) all output a UVB rating of 10.0 as stated for at least 6 months safely? Or is it buyer beware, expect a vet visit in 12 months because cheap is indeed nasty? https://www.ebay.com.au/itm/2X-10-0...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 https://www.petcity.com.au/reptile-one-compact-uvb-10.0-26w https://www.amazingamazon.com.au/repti-glo-compact-10-0-13w-uvb.html Many thanks all.
